; M7AM-1.ASM -- Apple ][ with Mountain Computer CPS card overlay for ; MDM7xx.ASM - 11/11/83. ; ; This overlay adapts the MDM7xx program to the Mountain Computer CPS ; card and the Soroc IQ-120 emulator within Apple CP/M. The LSTSTS BIOS ; entry is configured into the PARPRINT driver at the end by Ron Heiby. ; If you don't implement it, printer buffering won't work at all. ; ; Edit this file for your preferences then follow the "TO USE:" example ; shown below. ; ; TO USE: First edit this file filling in answers for your own ; equipment.
