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.
