- ; 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. Then assemble with ASM.COM or equivalent
- ; assembler. Then use DDT to overlay the the results
- ; of this program to the original .COM file:
- ;
- ; A>DDT MDM7xx.COM
- ; DDT VERS 2.2
- ; NEXT PC
- ; 4300 0100
- ; -IM7AM-1.HEX (note the "I" command)
- ; -R ("R" loads in the .HEX file)
- ; NEXT PC
- ; 4300 0000
- ; -G0 (return to CP/M)
- ; A>SAVE 66 MDM7xx.COM (now have a modified .COM file)
