- ; M8RB-1.A86 -- Overlay file for MDM8xx to run with DEC RAINBOW
- ; Communications port. 10/06/84
- ;
- ; This overlay adapts the MDM8xx program to the DEC Rainbow Communications
- ; port.
- ;
- ; 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 an external modem.
- ;
- ; 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 ASM86.CMD or equivalent
- ; assembler. Then use M8CNFG to overlay the the results
- ; of this program to the original MDM8xx.H86 file:
- ;
- ; ASM86 M8IN-1
- ; PIP MDM.H86=MDM8xx.H86,M8RP-1.H86
- ; GENCMD MDM 8080 CODE[MFF0]
- ;
- ; xx in MDM8xx represents the Version number of MDM8
- ; e.g.: MDM830, xx=30
- ;
- ; Now run MDM. Have Fun
