Well, if I can (at best) combine or (at worst) conflate two ongoing
topics... Why not just write an XModem driver for the HP 2100, and
connect to a PC as a BBS? Come to think of it, there are probably
XModem (or derivatives or competitors) protocol drivers for it
already...
On an unrelated topic, did you ever hear of Steve Schmidt? I used
to work with HP 21MX machines. He, in order to make a very useful
department computer at Michigan Technical University, wrote CP/M into
microcode on the 21MX. It was full multi-user, and he implemented Z-80
instructions in microcode, too. Oh, yes, the CP/M call was a single
micro-coded instruction. They used various CP/M commercial software on
it, and were quite pleased.
