- ; M7C3-1.ASM -- CP/M Plus overlay file for MODEM7. 11/19/83
- ;
- ; This overlay adapts the MODEM7 program to use the auxiliary device
- ; in CP/M Version 3.
- ;
- ; You will want to look this file over carefully. There are a number of
- ; options that you can use to configure the program to suit your taste.
- ; This file places particular emphasis on using the Auxiliary device
- ; properly configured under CP/M 3.
- ;
- ;
- ; 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 MAC.COM or equivalent
- ; assembler. Then use SID to overlay the the results
- ; of this program to the original .COM file:
- ;
- ; A>SID MDM712
- ; CP/M 3 SID - Version 3.0
- ; NEXT MSZE PC END
- ; 4300 4300 0100 D3FF
- ; #E M7C3-1.HEX ("E" loads in the .HEX file)
- ; NEXT MSZE PC END
- ; 031E 4300 0100 D3FF
- ; #W MDM712.COM,100,42FF ("W" writes the modified .COM file)
- ; 0084h record(s) written
- ; #G0 (return to CP/M)
