; M7PM-1.ASM -- PMMI overlay file for MDM7xx - 11/11/83
;
; 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 PMMI S-100 modem board.
; Much of the information contained here is not in the main file.
;
; Edit this file for your preferences then follow the "TO USE:" example
; shown below.
;
; PMMI users should set PULSERATE to its proper value.
;
;
;	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
;		-IM7PM-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)
