I am trying to create a qterm overlay for an Apple //e which uses the Microsoft Premium Softcard //e. This is NOT an "original" Softcard; this model has its own 64K and built-in 80 column card. I need to know how to call the ROM bios to read a byte from the Apple's memory, and how to write a byte to the Apple's memory. Unfortunately, we do not have the Programmer's Guide to this card, and nowhere can I find any overlays (for MEX, IMP, MDM7, etc.) that could be used as a starting point. This is a weird card -- it does NOT share Apple memory (with offset), like the original Softcard. If anyone can find this information in the Programmer's Reference, or from any other source, please contact me via email. Any hints appreciated. Thank you. tbopp ------------------------------------------------------------------------------- Tom Bopp INTERNET:tbopp@uhunix.uhcc.hawaii.edu Dept of Chemistry BITNET:tbopp@uhunix University of Hawaii UUCP:{ihnp4,uunet,dcdwest,ucbvax}!ucsd!nosc!uhccux!tbopp Honolulu, HI 96822 VOICE:(808)956-7463 FAX:(808)956-9508 -- ------------------------------------------------------------------------------- Tom Bopp INTERNET:tbopp@uhunix.uhcc.hawaii.edu Dept of Chemistry BITNET:tbopp@uhunix University of Hawaii UUCP:{ihnp4,uunet,dcdwest,ucbvax}!ucsd!nosc!uhccux!tbopp
