; 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)
