Yvonne -
Enclosed the two disks for your BMC computer. The one marked ? O.S. is
the one first described below. I know no more about it than the
following paragraph. I will be interested to hear from you as to how it
works.
This is the weird OS that I was referring to. It
is quite similar to IBM's PC-DOS BASICA but is a
complete operating system. BTW, it uses Z80 code
internally and not 8086/8088. (I've done a
partial disassembly which is how I know this)
The one marked CP/M 2.20/5 is the standard operating system for your
machine. Unfortunately, I believe that it lacks color which yours is
capable of. But at least it should get you up and operating. Following
are the comments from the chap who sent it to me.
This is the CP/M 2.25 OS made by Lifeboat
Associates back in '81. Lifeboat no longer
handles CP/M in any guise so you're not likely
to see any support from them. I got a less than
helpful attitude when I went to them looking for
BIOS source.
If I can be of any further help, please give me a call or drop a note.
