Microcode ROM's for the 2100 are 21MX boot roms.
21MX boot roms come in two flavors, the more common being the 24-pin,
1024 by 8 bit bipolar
devices.
Unprogrammed boot roms for the 21MX's are commercially available, but
the programming yield
is not great and they are expensive.

We're working on that. I've found a
stash of old **UNPROGRAMMED** PROMs
and I have a programmer that can program them but I need the correct
plug-in unit for it. Once I find one I think we'll be home free.
Sorry, I don't have any Prolog stuff... I have a Data I/O 29B with Unipak.
So, were the unprogrammed proms you found for microcode or boot roms? If
microcode, for 2100 or 21MX systems (I seem to recall they are different)?
Either way, care to let go of a few if you have a pile of them?
