[vcf-midatlantic] Looking for Help to make a MP/M Disk Image

After a lot of effort I repaired a Systems Group 2800 S-100 computer by
tracing the electrical faults related to old caps and a 7805 regulator. Now
it boots to the hard drive.
The system boots up and asks PASSWORD PLEASE-
I have tried various passwords but none work.
I found a binary of the MP/M OS that came with the SG 2800 here:
(search page for "Systems Group System 2800")
Is there anyone here who can make me a bootable 8" disk by using this
In the meantime I am going to see if I can make a generic MP/M disk boot
that will work this system, but it would be nice to get the disk the
computer came with running.
I don't have the skills to use the appropriate assembler, it has been years
since Dan Rogantis's class on building a CP/M (MP/M) disk from a binary of
the disk files. I suppose I could just copy them to a CP/M disk but I
doubt it will boot. If I keep at it I can probably get it to work but I
will accept help if this is an easy project for someone else. Suggestions?
