TITLE 'ZENITH 100 OVLY'
; M8HZ.A86 -- Zenith 100 overlay file for MDM8xx. 09/28/84
;
; This overlay adapts the MDM8xx program to the 2661 EPCI serial I/O
; chip used in the Zenith 100 series.
;
; 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.
;
; Edit this file for your preferences then follow the "TO USE:" example
; shown below.
;
; TO USE: First edit this file to chose your options.
; Then assemble with ASM86.CMD or equivalent
; assembler. Then use M8CNFG to overlay the
; the results of this program to the original
; MDM8xx.H86 file:
;
; ASM86 M8HZ-1
; REN M8OVL.H86=M8HZ-1.H86
; M8CNFG
; GENCMD MDM 8080 CODE[MFF0]
;
; Now run MDM. Have Fun
