; 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

; 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)
