This constitutes a bibliography of some of the references used in creating the PBClone library. They are listed in no particular order. I might note that many of these references contain incorrect information on one point or another and that they frequently contradict each other. Such are the joys of assembly programming. Comments reflect my personal opinions on the text. "The New Peter Norton Programmer's Guide to the IBM PC & PS/2". 2nd Ed, 1988, by Peter Norton and Richard Wilton. Microsoft Press. -- Often contains inadequate detail and is unusually buggy. The little bit it had of value has been superceded by more current works. Garbage. "COMPUTE!'s Mapping the IBM PC and PCjr". 1985, COMPUTE! Publications, Inc. -- An old but still handy reference. The memory map, port reference, and low-level support chip information are very good. "Programmer's Guide to PC & PS/2 Video Systems". 1987, by Richard Wilton. Microsoft Press. -- A terrific reference on video from MDA to VGA. The example program for putting the Hercules adapter into graphics mode is rather buggy, however. "The MS-DOS Encyclopedia". 1988. Microsoft Press. -- Encyclopedic it is, if getting a bit dated. Still, its coverage of DOS is excellent. Recommended for serious assembly language programmers. "Algorithms & Data Structures". 1986, by Niklaus Wirth. Prentice-Hall, Inc. -- Terse text with rather ghastly Modula-2 source listings. One of the few places where sorting and data structures are covered even moderately well, however. If you need to do sorts or b-trees, it's a mandatory text. "The Programmer's PC Sourcebook". 2nd Ed, 1991, by Thom Hogan. Microsoft Press. -- An astonishing collection of data and tables. With comprehensive scope but no depth, this reference can tease by providing insufficient detail. Still, a priceless work. Get one immediately. "Microsoft MS-DOS Programmer's Reference". 1991. Microsoft Press. -- Although books by Microsoft Press seem to have an unusual number of bugs, they are usually otherwise excellent. This one stinks. It lacks vital details, contains many serious bugs, and offers smugly hypocritical advice on program design. I haven't seen as much info on the DOS 5.0 National Language Support elsewhere, though, so it may make a tolerable last choice if you want to go international. Don't say I didn't warn you. "Sound Blaster: The Official Book". 1993. McGraw-Hill, Inc. -- Not as complete as one might like. Most of the book is concerned with idiot-level end-user stuff. An appendix details the hardware interface in an ineffectual manner, and the SB software drivers in a manner which is mostly sufficient for technical folks.
