This translation follows the same principle of using overlays
to adapt MDM8xx to different hardware environments as was so
successfully done with MDM7xx.
The procedure to adapt MDM8xx to specific hardware has changed
somewhat due to the facts that DDT86 cannot be used to overlay
H86 (HEX) files and no SAVE command beeing available in CPM86.
The Procedure is now as follows:
Required Files: MDM8xx.H86 (xx is Version Number)
The Main Program in Hex Form.
M8GP.A86 (The General Non-Specific
Overlay.
or
One of the available Overlays
for your hardware.)
After Editing your Overlay Source File to conform to your
Hardware environment, proceed as follows:
ASM86 M8GP ( Assemble the Overlay File )
PIP MDM.H86=MDM840.H86,M8GP.H86 ( Append Overlay to Main Program )
GENCMD MDM 8080 CODE[MFF0] ( Run GENCMD to produce MDM.CMD )
Now you can run MDM.CMD
The Translation was MAINLY done be hand as XLT86
( DRs 8080 -> 8086 translator) is virtualy useless with large files.
Various routines had to be changed to work properly with CPM86 and
MPM86
