The rest of this list will not cover the 6152 machine. More information on the 6152 processor is covered in the AOS FAQ posting in this newsgroup. The 6152 model was discontinued by IBM as of August 31, 1990. [ More details about the mysterious 6152 model RT would be intresting. How widespread is it? History? Are any still running? - MW ] There are three versions of the 6150/6151 processor card, and several unique RT models using each version of the card. IBM used the different model numbers to designate different base configurations of processor speed, installed main memory and installed hard disks. Model numbers can be deciving, as some machines may have been field upgraded to different models and/or processor types. The standard 032 processor card was in models: 10, 15, 20, 25 and A25. - 1MB memory was standard, with expansion available, via 1MB, 2MB or 4MB memory boards. - Optional Floating Point Accelerator was also available. - AIX 1.0 and 1.1 (RT version) initially shipped with these models. - 170ns processor cycle time. - The models 10, 20 and A25 were discontinued October, 1988. - The models 15, and 25 were discontinued May, 1990. The Advanced processor card was in 2 different types: The 115 which had 4MB memory ON the processor card, available only on the desktop 6151. The 125 and B25 models which had all their memory on external FAST ECC 4MB memory cards, used in the 6150 tower models. - Memory expansion via 4MB FAST ECC memory boards. - Built in 20Mhz Motorola 68881 floating-point processor. - Optional Advanced Floating Point Accelerator was also available. - These models required AIX 2.1 as a mininum. - 100ns processor cycle time. - Later 8MB FAST ECC memory boards became available. - The models 115, 125 and B25 were discontinued May, 1991. The Enhanced Advanced processor card: Available only with the model 135 and B35 (6150 tower), and with the model 130 (6151 desktop). - On-board 16 MB main memory standard. - Motorola 68881 was removed and the Enhanced Advanced Floating Point Accelerator was made a standard feature. - These models required AIX 2.2 as a mininum. - 80ns processor cycle time. (Much faster!) - Rated by IBM at 5.6 Mips. - The models 130, 135 and B35 were discontinued May, 1991. Enhanced Advanced processors are easily recognized. Soldered directly to the processor board are 20 'SIMM like' memory boards sticking up on about 1/2 of the processor card. All processor cards are installed in the special board slot labeled 'A'. The A## and B## model machines shipped without the native keyboard, and instead used a preinstalled 5080 attachment interface card allowing the RT processor to share the keyboard that was attached to the 5080 graphics system hardware. Via a special interface card, the 5080 lighted program function keypad (LPFK) and dials unit (three variable position X,Y and Z controls) could be attached either to the RT or the 5080 graphics system. Primarly used in a CADAM and CATIA setup running AIX.

[ I would like to see some results from users with later benchmark tests on both the native C and Fortran compilers. Tests with a 135 processor using the last available compiler patches from IBM, and side-by-side tests with the now available GCC compiler for AIX RT would be an intresting addition to this section. I would like to see how those compilers stack up to each other in performance tests. I would also like to see how the RT still stands using some of the newer industry standard benchmark programs. Comparisons against other popular processors now in use would be intresting. This information may be dated, considering that IBM continued to improve the performance of the native C compiler available with the AIX V2 operating system. Comparison running AOS or MACH would also be intresting to see how much difference compiler and OS technology has on overall performance. Challenge anyone? - MW ] Note: These performance numbers are dependent on various factors, including complier update levels, language, Fortran or C, compiler options, and instlled floating point accellerators. Times given are using the AIX operating system. These numbers were obtained from an IBM announcement letter number 188-120 Dated July 19, 1988, announcing the release of the 135 Enhanced Processor. Refer to that IBM announcement for more complete information.

ANS/Merit could probably give you more details on when this switchover occurred, but I believe that November 1992 was one of the official changeover dates. ==**==**==**==**==**==**==**==**==**==**==**==**==**==**==**==**==**== Submitter: (Gerald Oskoboiny) Last night I was reading "Computer Wars" by Charles H. Ferguson and Charles R. Morris (ISBN 0812921569, Random House, 1993), and it has the code names of the RT and other projects. I forget most of the details, but it is very interesting reading. It explains how IBM had RISC technology in 1968 but mismanaged it until the disappointing RT was released in 1986. As far as "history of the RT" goes, this book explains it all. ==**==**==**==**==**==**==**==**==**==**==**==**==**==**==**==**==**== Submitter: mike@neutron.amd.com (Mike Johnson) Newsgroup: comp.arch Subject: Re: First Commercial RISC Computer That's Research OPD Mini Processor. OPD = Office Products Division. ROMP was originally designed to be used in office products, primarily text editing systems such as the IBM Office System/6 and DisplayWriter. The architectural work started in late spring of 1977, as a spin-off of the T.J. Watson Research 801 work (hence the "Research" in the acronym). Most of the architectural changes were for "cost reductions," such as adding 16-bit instructions for "byte-efficiency"--a main concern at IBM at the time. The first chips were working in early 1981. The delay from architecture to working chips was caused mainly by building two models of the chip in TTL: an emulator that just executed the instruction set and a nodal-equivalent model that was more-or-less an exact duplicate of the chip (about 6000 7400-series DIPs plus a number of IBM bipolar gate arrays and static RAMs). The delay was also caused by two major revs to the architecture: one change to a 32-bit architecture from a 24-bit architecture (I'm serious), and another to support demand paged virtual memory (the implementation supported out-of-order loads, so precise interrupts were hard to come by). ROMP was arguably the first working commercial RISC. The arguments would be over whether or not it was a "true" RISC and whether or not one could count it as a commerial product in 1981, since it didn't actually ship until 1986. *This* delay, in my opinion, was caused by overly ambitious software plans, in the form of porting an IBM version of UNIX to a virtual software layer called VRM (Virtual Resource Manager), rather than porting Berkeley UNIX directly to the hardware. The path from having hardware to developing VRM to porting UNIX and then getting VARs to write applications was just too long--a problem that IBMs resources couldn't overcome. I was the first member of the ROMP design team--something I credit to random chance rather than any personal expertise (my graduate work at the time had been in digital control systems). ROMP was a good way to learn microprocessor design by learning what *not* to do. I understand that ROMP was also used in an IBM laser printer, but I don't have any first-hand knowledge that this is true. ==**==**==**==**==**==**==**==**==**==**==**==**==**==**==**==**==**== ------------------------- H.2 - What types of processors were made? There are 2 basic types of machines called an RT. The tower model, IBM machine number 6150. The desktop model, IBM machine number 6151. There exists a special version machine that used the same processor, available only to educational sites that is a hybrid IBM PS/2 model 60 with a special mirco-channel board version of the 032 processor, dubbed as a 'crossbow' board. [project name? -MW] That machine was IBM machine number 6152. The 6152 ran only the AOS operating system downloaded from another IBM 6150 or 6151 also running AOS, via a lan TCP/IP interface (either Token-ring or Ethernet). Later versions of AOS could be loaded directly on the 6152 once larger hard disk drives for PS/2 became available. The availablity of support for VGA adapters in the X11 releases was because of the existance of this machine. I am not sure the 6152 machine can rightly be called an RT, as the only interface boards used were the same as used in PS/2 machines. This version may be somewhat rare, and I havserial numbers BELOW a selected value were a different upgrade. However, the upgrade announcement letter (187-022) does NOT mention a planar upgrade in its text. The only planar problem I know of was with REAL old model RT's not working with ethernet adapters.. here is a cut of the 6150 model hardware information..dated Feb 26, 1991. ================= start cut of IBM info =============================== Hardware Requirements: The Baseband Adapter will plug into any model of the 6150 and 6151 system units. Software Requirements: This product requires that the RT AIX Operating System Version 1.1 (59X8994) be installed. Limitations: The Baseband Adapter must NOT be plugged into slot 8 on the 6150 Models 020, 025, and A25, or slot 5 on the 6151 Model 010. Planar must be at, or higher than, EC A31282M on the 6150 Models 020, 025, and A25, or EC A31283M on the 6151 Model 010. If the customer serial number is 3500 or lower on Models 020, 025, and A25, or lower than 2250 on Model 010, have them contact IBM for an upgraded planar board. There will be an "Attention" card placed in each Baseband Adapter box. The upgraded planar board will be installed at no charge to the customer. ================= end cut of IBM info =============================== [ I am still searching for more complete upgrade information. IBM had some specific minimum planar serial numbers that were required for the faster processors, but I do not have any of that information. Anybody? - MW ] ------------------------- H.5 - How can I tell what kind of processor type is installed? For a quick determination of the processor type, observe the LED digits during a power on IPL. The general sequence for initial 'Power On Self Tests' (POST) codes is: 88, xx, zz, yy, 09, 10, 14 (long), 15, 16, 21, 22 The XX, YY and ZZ LED values will have a value of: XX YY ZZ 01 03 05 = Standard 032 processor. (010,020,025,A25) 1c 3c 5c = Advanced 032 processor. (115,125 and B25) 1u 3u 5u = Enhanced Advanced 032 processor. (130,135,B35) The XX and YY codes stay around the longest, and are easiest to see. A few other codes fly by as well, but try as I could, I could not tell what they were. Other codes can show up, depending on what other I/O boards are found in the system during power up. If any code remains in the LED display for over 5 minutes, a failure had been found with the system during self tests. All LED codes after the code 22 (boot record processing), are dependent on the operating system being loaded into the RT. LED codes prior to the 22 are placed in the LED display by the Power On Self Tests (POST) of the RT planar. Almost all the other LED codes are displayed by Loadable POST (LPOST) routines invoked during VRM initialization and IPL. Obviously systems NOT running AIX with VRM will have different LED codes. ------------------------- H.6 - Where can I get parts for RT systems? [ This section needs more entries, addresses and/or phone numbers. Third party suppliers or used equipment dealers known to deal in RT hardware would be great. - MW ] Parts at this time are still available from IBM. At this time, IBM does not have any announced discontinuance of individual parts. As of September 15, 1993, IBM has announced (letter 193-161 dated June 15, 1993) discontinuance of selling all the different monitors (6153, 6154, 6155, 5081) and some of the external perheriperials (6156, 6192). The 6157 tape drive was discontinued earlier in the year. IBM still offers maintence contracts for RT computers and equipment. IBM parts may be ordered by calling IBM-Direct, 1-800-426-2468. Other IBM numbers: 1-800-426-7378 Service/Maintenance 1-800-426-2468 Supplies/Dealer Referral 1-800-426-3333 Information However, IBMs prices may be a little steep. Some used and surplus parts houses from time to time get RT systems, but not on any regular basis. Lots of times, they are broken up for some of the re-usable parts, and the rest junked. :-( Dickens Data Systems used to make special 8, 16 and 64 port async adapters for RT systems. They also sold device drivers for various SCSI attached devices, including 9-track tape. I am not sure if they still make any of these. ==**==**==**==**==**==**==**==**==**==**==**==**==**==**==**==**==**== Submitter: rrogers@chinet.chinet.com (Richard Rogers) [ I have made a few editorial changes and corrections to Richards submission, mostly phone number corrections or address/contact corrections. - MW ] In searching for a source of RT Megapel cards I put a call out over the net for RT parts sources and said that I would summarize back to the net.

The IBM RT has what is called in the industry a ISA bus. Based on the original IBM PC AT bus in design, the RT has 8 I/O slots in the tower (6150 model), and 6 slots in the desktop (6151 model). Slot 3 and 6 on the tower model and slot 1 on the desktop models are eight bit style slots. Slot 8 on the tower and slot 5 on the desktop model are wired slightly different than standard. Technically, any adapter that conforms to ISA standards would work provided there are appropiate device drivers AND no conflicts with existing adapter registers and bus addresses. The RT diagnostics program disks are unfortunately rather particular about OEM cards that emulate IBM adapters. This can sometimes lead to problems running diagnostics, where the system MAY otherwise run fine with the regular operation system. NOTE: See the OS dependent FAQ list for additional hardware that may be supported by that operating system. The information and part numbers shown below generally reflect AIX usage. Feature code numbers and part numbers, where known, are shown in parenthesis like this (#feature,partnum). Part numbers DO change with EC (Error Correction) changes and production run changes.

How do I make my own RS232 cables compatible for use with AIX? The funny connector on the back of the 6150 labeled 'S1' and 'S2' are the native serial ports built into the system planar board of the 6150 tower models of the RT. This connector is refered to in the IBM hardware manuals as a MODU connector. The 10-pin connector used on the native serial ports, is also used by the fan-out box for the RT RS232 8-port card. These part numbers for the connector were given to me by the IBM support center in Austin, TX for the RiscSystem/6000. The 6000 has the same 10 pin MODU connectors for the 6000 systems native serial ports, and is the same connnector used by the RT systems native serial ports. AMP Product Corp.

While most of the signals are the same, there are four major differences: 1) There is a speaker in the keyboard. 2) The physical connector is not the same. 3) Some of the scan codes are different. 4) Some of the programing commands are not implemented in the AT keyboard. Difference 1 and 2 are managable, but 3 and 4 imply some way is needed to alter the keyboard ROM chips, or basic hardware. [ ANY input on how to hack a keyboard for RT compatibility is gladly welcomed! - MW ] ------------------------- H.14 How do I get a parallel printer attached to an RT? [ This information has been taken from the AIX manuals, if there is a difference for AOS, let me know. - MW ] There are three different ways to attach a centronics parallel printer to the RT. A maximum of two parallel printer interfaces are supported, but only by using a AT serial/Parallel card, jumpered at the secondary printer port address. 1) AT Serial/Parallel interface card. Parallel port primary address = 3BC Parallel port secondary address = 278 2) PC/XT Monochrome/Parallel printer card. Parallel port only address = 3BC No jumper available to disable this port. 3) Megapel card has a parallel interface on it. Parallel port only address = 3BC Swich 1 position 2 enables/disables the port. Shipped disabled from factory. Recent discussions in this newsgroup indicate that clone printer port cards will work with AIX. Personally, I have used both the AT Serial/Parallel card and the XT monochrome adapter just fine to run parallel printers. ------------------------- H.15 What are the switches on the Megapel adpater for? Technicial information on Megapel adapter and display. Switch 1 is located on the display processor card (the one with the 25-pin parallel printer connector on it). 1 Not used.

The amount and type of support for SCSI devices varies by the operating system used. Please refer to the different RT operating system specific FAQ list for more information about SCSI support. The IBM suported SCSI adapter is a 'Differential Driver/Receiver option' with the 'Alternative 2 connector'. The SCSI interface conforms to (then) proposed ANSI standard X3T9.2/82-2 Rev. 17B. Two wires are used for each signal lead in a push-pull signaling method also called 'differential-ended'. Most drives for other vendor workstations and PCs use a 'single-ended' SCSI implementation. What this boils down to is that the IBM SCSI card is electriclly incompatible with a lot of the off-the-shelf SCSI drives. IBM officially supported only one device attached to the SCSI interface card, the 9332 'Athens' disk drive. However, all is not lost. :-) Some vendors do offer their SCSI drives with an optional differential interface. There also exist a couple of manufacturers of 'Differential-to-single-ended' converter boxes. These boxes allow a bi-directional conversion of the SCSI bus and will allow attachment of these single ended disk drives. See the AIX FAQ for more information about using OEM SCSI disks on an RT using the IBM SCSI board. Under the AOS operating system, several people have modified the system to use an Adaptec SCSI controller. That controller uses single-ended devices. [ More information about this Adaptec controller can be found in the AOS specific FAQ list. - MW ]-------------------------H.22 - What do the LED codes mean during power on?

LED codes displayed while running vary greatly depending on the operating system used. Please refer to the different RT operating system specific FAQ list for more information about these LED codes used.-------------------------H.24 - What is different about the RT I/O slots. What cards will run in slot 8. The IBM RT 6150 and 6151 system units use ISA (AT) style I/O slots, however slot 5 on the 6151 and slot 8 on the 6150 are unique to the RT. Most cards that do not use memory refresh, or DMA channel 7 will have no problem with that slot. Bus timings may be slightly different, from an AT, as I/O accesses are not driven by the processor directly, but are routed via a special bus processor called the IOCC. The 8th slot in the 6150 RT and the 5th slot for the 6150 only have three signals different from the normal PC/AT assignments. Pin Standard CO-proc slot usage My notes.. B19 REFRESH + SPK DRV (Wire or'd to speaker control) D14 DACK 7 - DACK 8 DMA channel is reassigned.. D15 DRQ 7 + DRQ 8 .. ditto The following cards cannot go in slot 8: - AT 512Kb Memory expansion card (no refresh signal available). - Baseband adapter (Ethernet, Ungerman-Bass) [Timing?? -MW] - SCSI adapter ONLY when it is using DMA channel 7... channel 7 is not connected to SLOT 8. These cards require special slot placements: - EGA adapter only in slot 3 or 6 (6150) or slot 1 (6151). - Megapel adapter is two boards sandwiched together, and can only be installed in slots 4 & 5 in a 6150 tower. It can also be installed in slots 2 & 3 (prefered), slots 3 & 4, or slots 4 & 5 (least prefered) in the 6151. [ It has been noted via discussions in this newsgroup that the the later X servers will have problems, errors and timing problems if the megapel adapter is NOT placed in the prefered slots! -MW ] - AT-Coprocessor in installable ONLY in slot 8 of the 6150 tower, or in slot 5 of the 6151 desktop. (That's why it is called the coprocessor slot! :-) - The PC XT mono/printer adapter, is ONLY supported in slot 3 in the 6150 tower, or ONLY in slot 1 in the 6151 desktop. [ I'm not sure why this slot 3 restriction is here, what's wrong with slot 6? Timing? - MW ] IBM Mono Adapters with Part numbers 1804065, 1804073 or 1501667 cannot be used according to the parts book that I have seen. The options book indicates that those part number mono adapters will not operate correctly with an RT. I have had reports that clone monochrome cards also may have problems running in an RT. I have not tried them myself. Any 8-bit card is better off in slots 3 or 6 (6150) or in slot 1 (6151), as those slots are 8-bit only anyway. Save a 16-bit slot for a card that needs it.-------------------------H.25 - How do I run diagnostics. IBM supplied with most RT systems several books, one set of three books are maroon in color, and contain setup, install and one book labeled "IBM RT PC Problem Determination Guide" (RT PD). The Problem Determination guide is usually composed of two manuals in one binder. IBM manual number SA23-2604, and for those users who ordered AIX with their systems, it also contains SA23-2603 titled: "IBM RT AIX Operating System Problem Determination Guide". This binder also contains three diskettes with maroon labels. Volume one of the three diskettes is bootable, and when booted, causes it to examine the system hardware, and place a menu of diagnostic options on the screen. Most of the diagnostics are menu driven and are self-explanatory. The RT PD guide will take you thru any special procedures if necessary. Further problem diagnosis is available in the dark blue book with the title "IBM RT PC 6150 System Unit Hardware Maintenance and Service" Manual# SA23-2605 or Part Number 22F9803. This book contains problem isolation charts, part numbers, installation information and a SRN (Service Request Number) to FRU (Field Replaceable Unit) part index. This book also contains a LED fault code to SRN reference, as well as probable failure part analysis charts. -------------------------H.26 - Serial port cards maximums and limitations. NOTE: The following information is gleaned from the IBM announcement letters and general information sheets. It is the only information I have acess to and concentrates on the limitations imposed by AIX 2.2.1 on the RT hardware, the only announced OS IBM supported for the RT systems. AOS users report that the baud rate limits have been exceeded up to 56Kb by modifications to the standard AOS kernel. I am not sure at this time what the exact speed capabilities and limitations may exist with the modified AOS kernel. - MW * The internal serial ports of the 6150 tower model RT are normally able to run at a maximum of 19.2K bits per second. * The IBM RT 8-Port Adapter is capable of all 8 ports operating concurrently at 19.2 K bits per second. * All 8-Port Adapters installed in a single system unit should be set to the SAME interrupt level for best performance. * For proper software operation, 4-Port Asynchronous Adapters must be set to a DIFFERENT interrupt level than 8-Port Adapters, when installed in the same system unit. * IBM RT 8-port Adapters in the 6192 Expansion Unit should be set to DIFFERENT interrupt levels. Interrupt sharing is not supported between the IBM RT System Unit and the 6192 Expansion Unit. * A maximum of EIGHT 8-port Adapters can be installed on a system. (e.g. 6 adapters in the 6192 Expansion Unit and 2 in the RT system unit) * Concurrent use of 4-Port Adapters and/or PC AT Serial/Parallel Adapters and/or 6150 native Serial Ports with the 8-Port Adapters may result in reduced performance on the devices attached to the 8-Port adapters, depending upon line speeds and device usage. * If a 5080 Peripheral Adapter is installed in the system unit, the maximum numbe-------------------H.20 - What are the characteristics of the various IBM RT disk drives?

I have seen an R70 and E70 side by side, and they are identical, and are 'IBM type 0667' drives! [ Are there some other 'R70' drives out there?? -MW ] Note 2: intrl = Sector interleave value, sects = Sectors per track. Note 3: The MAXTOR documentation indicates that the drive normally has 36 sectors per track, yet all the IBM drive tables and documentation indicate differently. See also the VRM table below. An intresting recent addition is this table I built by examining the VRM utility format program. When you need to reformat a new or non-IBM drive, this utility will place the minidisk partition table and other IBM required identification information on the drive. While you can enter non-standard paramenters, built into the program are the parameters for all the IBM drives. Anybody know the reason for the discrepency? Which is correct?

The "Ported" or Portable Drive adapter was a special version of the standard Extended ESDI controller that had the same identical layout, jumper and pin configuration as the "later" version of the Extended ESDI controler. The one difference was an external connector on the end plate of the card that could hook up the IBM "Portable drive bay" enclosure. The portable controller had the same connectors in the middle, and I suspect that the "portable" controller was not any different from the stock controller. In a non-standard configuration, I have run run 6 ESDI drives by having a standard Extended ESDI controller in slot one and a PORTED controller in slot 2. The portable controller even had to be jumpered to the "secondary" position for installation. I also have tested the card in the primary position (undocumented on the jumper setting in the manual, but it looked JUST like the standard EE-ESDI card!) running the internal E310 drives, and it worked just fine. Part Number, 08F3612. I/O addresses used: [looks like secondary addresses to me! - MW] Drives F, G and H - 0170 - 0177 and 0570 - 0577 DMA channels FIxed disk = 1 or 3 (set by program).

IBM 9332 DIRECT ACCESS STORAGE DEVICE No Longer Available, for ordering by IBM US as of May 17, 1993. The IBM 9332 "Athens" fixed disk drive has models with both IPI-3 and SCSI interfaces. The only version attached to the RT was via the differential SCSI interface. During boot time the AIX operating system has the ability to download microcode to the drive. The Models 240 and 440 drives are intended to be Rack-mounted in a 9309 Rack Enclosure. The Models 250 and 450 are mounted in a standalone enclosure providing cooling and power. The pinout of the SCSI connectors on the back of the 9332 conforms to (then) proposed ANSI standard X3T9.2/82-2 Rev. 17B, In accordance with that standard, the 9332 uses the 'Alternative 2' style shielded connector, wired for differential SCSI devices. NOTE: These are the only model 9332 drives issued with SCSI interfaces. Other model 9332 drives use an IPI-3 interface.

The Token-Ring card has a 9-pin female connector, and usually a green dot sticker on the metal plate, but not always. The adapter card had two versions, early and late. For both versions, with J1 and J2 to the left, indicates no proms are installed in the sockets shown by the XXX's. ----------------------------------------------------- --- | ... ... +----------+ ... || | J1 J2 |small card| J5 ||=| 9-pinconnector | +----------+ ||=| | XXX || | XXX || early card | XXX YYYZZZ J3 || --------------------------+ +--+ +----+| |_____| |____________| | ----------------------------------------------------- --- | ... ... ... ... || | J1 J2 J5 J6 ||=| 9-pinconnector | ||=| | XXX || | XXX || late card | XXX YYYZZZ J8 || --------------------------+ +--+ +----+| |_____| |____________| | During installation, make sure that the interrupt/DMA level does not conflict with any other card, and that the I/O and DMA address jumpers match, in accordance with the devices settings. Note how the address and DMA settings travel together. I/O range DMA J5 J6 01c0-01cf 5 up up 0140-014f 6 up down 11c0-11cf 7 down up (see note below) 11d0-11df 3 down down (can conflict with serial port 1) The 11c0 address cannot go in slot 8 of the tower (6150) model 25 or slot 5 of the desktop (6151) model 10. DMA channel 7 conflicts with use of the megapel adapter. DMA channel 3 conflicts with serial port 1 (S1) on the planar. Only a problem if you have that port defined via devices, otherwise you can use DMA channel 3. The early version of the RT Token ring card can only go at ONE of two possible addresses. It is recognized by having a daughter card plugged on it about in the middle of the card (sometimes). It also has a J1 and J2 jumpers in upper left and a J3 jumper in the middle of the card along by the gold fingers, and a J5 address jumper only. I personally have never seen the 'early' version of the RT Token card. See page 1-21 of the 'User Setup Guide and Options Installation manual' for more complete matrix of interrupt/DMA conflicts.-------------------------H.37 - What are the differences between the 032, APC and EAPC processor types. The standard 032 processor in the original models of the RT had the following features: * 170 Nanosecond processor cycle time. * 16 32-bit general purpose registers * 16 32-bit system control registers, including: - countdown timer register - exception control registers - interrupt request buffer register - instruction address register * 118 2 and 4 byte instructions with storage, branch, control, and integer math, including multiply and divide step instruction. * Memory Managment Unit with translation look-aside buffers, and address translation including: - 40-bit virtual address. - 256 Megabyte memory segments. - Multiple independent virtual address spaces. - address space size of 4 gigabytes. - demand paging. - page size of 2048 or 4096 bytes. - Memory protection. - Real memory addressability of up to 16 Megabytes. - Hardware assist for load real address The Advanced processor (APC) has these enhancements to the original processor. * 100 Nanosecond processor cycle time. * Overlapped Load and Store operations. * Several instructions are serialized to allow for better memory and I/O operations. * Additional exception control register information. * Instruction prefetch, and 16 byte loop detection. * MMU allows multiple outstanding load and store requests * On board 20 Mhz MC68881 floating point processor. - Trigonometrice and transcendental functions. - Seven different data types and conversions. * I/O interface enhancements. The Enhanced Advanced processor (EAPC) has these changes from the original and APC processor. * 80 Nanosecond processor cycle time. * 16 Megabytes main memory on the processor board. * Faster operation of the MMU. * MC68881 and one I/O chip removed. * Intended to be used with an Advanced Floating Point Accellerator. -------------------------H.38 - Speed and capability of the Floating Point options for the RT computers. FPA, MC68881, AFPA. All models of the RT systems running AIX can run with no floating point hardware assist and provide for simulation routines for floating point operations. The standard Floating Point Accellerator (FPA) contains instructions for general floating point operations, but does not include direct hardware support for trancendental functions (sin, cos, tan, ect..). The model 115 and 125 computers, with the Advanced Processor card include a Motorola MC68881 chip running at 20 Mhz. This chip is faster than the FPA, but not as fast as the Advanced Floating Point Accellerator (AFPA). In genral the FPA is slower than the MC68881, which in turn is slower than the AFPA. The FPA advantange is it can run in parallel with the processor, providing some overlap of operations.-------------------------H.39 - Where can I obtain a replacement battery? The battery located under the front cover of the tower model RT next to the keylock, and inside the case on the desktop unit behind the keylock mounting bracket. It maintains the real-time clock for the system when the power is off. It also maintains the non-volatile ram (NVRAM) contents. The NVRAM contains several items, among which are: the last error record, and the current list of boot devices. ==**==**==**==**==**==**==**==**==**==**==**==**==**==**==**==**==**== Submitter: Matt "C P." Rush Subject: RT batteries through Radio Shack Date: 26 Oct 93 21:10:43 GMT Just in case anyone out there needs to replace the battery in their RT, they can be Special Ordered through your local Radio Shack. Amazingly, the IBM-RT is actually listed in their battery cross- reference, but in case YOUR Radio Shack is lame, the part no. is: CLB-5293/W The painful thing is the PRICE: $15.99. I decided that it wasn't that bad to do a 'date' command every time I booted up. :-) ==**==**==**==**==**==**==**==**==**==**==**==**==**==**==**==**==**== My notes here.. This is average price for a lithium computer battery. The batteries on some RT systems that I have used, have lasted as long as 6 years before needing replacement, others are still going strong, so it is a relatively small price comared to other replaceables. Someone asked: > Are these batteries any different from garden-variety AT batteries? There IS NO one common AT battery. Some are 3V some a 6V. Some are plug in, some snap in more traditional battery carriers. The RT battery (IBM P/N 6299201) for the RT is 6.8 volts! Last I heard, IBM wanted $25.00 US for a RT battery. The Radio Shack battery sounds like a good deal, if it is a proper replacement. I have seen FIRES start in an RT that had an improper battery! At least one user has reported using AA batteries in a traditional carrier. As always.. caveat emptor, user beware, your milage may vary, ect.. - MW.-------------------------H.40 - RT 6157 tape interface card pinout and drive information.> I have a type 6157 RT tape drive here, and I'm trying to find out what> sort of interface it uses. It's the 45 meg 1/4" cartridge drive, and> popping it open revealed a Cipher modem 540 (or 640?) tape mechanism.Depending on the model of the drive, it is either a model 6157 (plain,with no dash) 60 Mb capabile (QIC-24 format tapes) drive or a model6157-2, 150 Mb drive (QIC-120 or QIC-150 format tapes) on write/read.Both models can read QIC-24 only the model 1 (no dash) can write QIC-24. The interface is used with either the IBM RT interface card, or acompatible vendor QIC-02 interface. This is a industry standard interface,so you may be able to find another interface card that will support it.IBM used this drive on several pieces of equipment besides RT systems:6152 (PS2/60), and AS/400 and mabey others.I have never examined the internal works on one, so I am not sure of thepinout of the internal connector used between the IBM 37-pin cableand the internal transport. I have no information on the actualtransport itself. TANDON or CIPHER made the drives for IBM, and lotsof other vendors.The orignal cable terminates in a 37 Pin Male D-Shell connector.

(-Online..ect..) * All grounds in pins 1-18 are attached to internal ground on the interface card. * All DATA interface leads appear to be driven by 74LS640's pulled up to +5v by a 220/330 Ohm DIP resistor pack. Thus... TTL level interface. * Status leads are driven/recived by a 74LS244 constantly enabled. * Input status leads: (From drive to interface) Exception, Direction, Ack, Ready * Output status leads: (From interface to drive) Request, Reset, Transfer, Online * The IBM interface card uses a 8042 mated to a 82S105 for interface controller duties, plus lots of 74LS support chips, plus two TMM 2016 ram chips.-------------------------9.0 Credits, Acknowledgements and other information.X.1 - Acknolowgements and copyright information.This file is provided AS IS with no warranties of any kind as to theusefullness/correctness of these procedures/questions.
