From: Marco Papa <papa%USC-CSE@USC-ECL.ARPA> I would like to know whether anyone on the net has information about the I/O addresses of the Clock-Calendar chip of the Microsoft SystemCard. The documentation that comes with it is absolutely terrible. It just says that "the SystemCard clock/calendar is similar to the IBM system clock". A call to Microsoft Product Support Department produced nothing since they cannot disclose this information. A very different policy from AST that documents thoroughly everything about its hardware. I would like to use the SystemCard with PC/IX as Herm Fisher's astclock program in the info-ibmpc library. The I/O addresses I am looking for are as follows: counter - seconds counter - minutes counter - hours counter - day of the week counter - day of the month counter - month counter - year (-80?) Thanks for any help. Marco Papa ARPA, CSNET: papa.usc-cse@csnet-relay UUCP: ..!randvax!uscvax!papa
