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.
While I'm at it I might as well post my plea for the programming module
aagin.
I picked up a couple of Pro-Log M900, M920 and M980 programmers lately.
I want to burn some BiPolar PROMs and I need a Pro-Log PM 9048 "Intel
Generic" personality module. It will look something like this
<http://www.classiccmp.org/hp/pro-log/person-harris.jpg>. I'm also looking
for other Pro-Log parts and I have parts to trade so if you have anything
that you're willing to part with send me a list. Here's more pictures on
my Pro-Log stuff. No text or descriptions yet, just pictures.

How available
are contemporary replacements
and/or new old stock for the ICs?
The bus driver IC's (DTL if I remember right)
are scarce... BUT... there are
so many 21MX's still in production use, most cards are plentiful, as are
thus dead cards with bus chips that can be snagged. Microcode and boot roms
(blank) are not impossible to find, but a bit scarce.
more problematic.
