If you put together CP/M from the OEM kit, you used it to make your
customized copy of MOVCPM.
Right. But there was also some application software that did this as well.
Wasn't JRT
the one that got some really bad reviews in Byte or one of the
other magazines? It was some early Pascal compiler anyhow. I can't say
I ever encountered it or ran across it or talked with anybody who had
used it.
I still have my 8" JRT disk. Yes, it was terrible and slow, but what do you
expect from a program that swaps to floppy? They advertised that you could
write programs of any size, not limited by the RAM of your computer. While
it was probably true that you could write programs much larger than
available RAM, the d*mned thing was buggy enough to be useless.
It's the bugs that were reported back when, if I'm remembering right.

I remember one
of the floppies I got with my Osborne originally was
labeled "UCSD P-System" (or something pretty close to that). I vaguely
recall poking around with it once, but it had nothing at all to do with
CP/M, wasn't compatible with anything else at all, and at that point in
time I couldn't see the use of it. I probably still have it somewhere,
and some docs on it too.
Yup, UCSD P-system was its own operating system as well as the
language support. Not a bad implementation for the time, but a world
unto itself. I think at one point IBM even flogged it for the PC.
Apparently. A side-trip into wikipedia turned up some interesting reading on
that, and other somewhat related subjects, before I was too tired to
continue last night. :-)
