NCR Corporation Date: January 14, 1992 To: PC6300 Users Subject: CLOCK402 Driver CLOCK402.SYS is an installable device driver that supports the date-and-time clock on the PC 6300, 6300 PLUS, and 6300 WGS computers. It has no effect on other computers. Installation Procedures Place the program disk in drive A. At the DOS prompt (C:), type copy A:\*.* C:\ and press Enter. (Most people use drive a:, but you may have another available floppy drive, B:.) Insert a command line of the following form in your CONFIG.SYS file: device=[drive:][path]clock.sys [year]where: drive = drive containing the CLOCK402.SYS file path = directory containing the CLOCK402.SYS file year = determines the base year used in date calculations. For your computer to keep the date accurately, the base year must be no more than eight years before the present year. To install CLOCK402.SYS with a base year of 1989, you would insert : device=c:\clock402.sys 1989 Reboot the Machine and use the Date and Time command to set the current date and time. This should now setup the machine to keep track of the date properly even after reboots. You will have to set the date and time once a year when the year rolls over. *** DISCLAIMER *** The SOFTWARE clock driver may not work correctly with unsupported PC6300 DOS Versions, such as DOS 3.3 or higher, or non-AT&T DOS versions. SOFTWARE applications which load into a memory range that conflicts with the SOFTWARE clock driver may cause unpredictable results. Any SOFTWARE applications which continue to read the HARDWARE clock instead of the DOS clock WILL continue to see the wrong date.

NCR has used reasonable efforts to minimize defects or errors in the SOFTWARE. However, you assume the risk of any and all damage or loss from use, or inability to use the SOFTWARE.
