I'm thinking now that it might be nice to have the monitor source typed in
so maybe I will take on that challenge. ?I've yet to encounter a method
of scanning and OCRing dot-matrix printouts that works so I think that
just leaves typing it in.
I was able to dump the 8355 and reprogram it into an 8755 for an
SDK-85 I have. I should be able to send you a dump for that later
today if someone else doesn't beat me to it.
For the HP 5036A monitor what I did there to create an accurate
monitor listing without completely starting from scratch was to feed
the monitor dump into a special purpose disassembler I wrote and then
typed in all of the comments from the printed listing. That took a
while to finish and verify for correctness. This was the result:

Might not be too bad to repeat that process with the SDK-85 monitor.
