HP 2100S microcode blanks?

[Bob Shannon]

I do!

I've actually got the HP plug-in card and programmer to program these
parts.  I also have a paper tape of the prom burner diagnostics, and the
interface manual for this set.

I can try to dig out the info, or I can loan you the whole set.  If you wish
we can arrange a trade if you want to own this stuff.

The 2100 microcode rom burner can also be used to burn 21MX boot
roms, so there is a chance that they are the same parts.
