I can attest to a flakiness of the SDK-85 operation if the pin is not properly selected.
My board had a 8355 and it failed. I replaced it with a 8755A and it was flakey because I
did not change the ROM pin select. After correctly connecting the ROM pin, all worked
fine. I have a SDK board and the manuals if you need any information.

Hi
As was mentioned, there is a different pin on the 8755A than
the 8355 used on the sdk85. Did you check that it was
at the correct level?

Thank you Carl. I did receive a .BIN file of the monitor a while ago
and just recently got it burned into an 8755A. Unfortunately, this has
not fixed the problem-- or, rather, introduced a new problem as the
little machine still does not run at all (frozen or not) with the new
EPROM resident monitor.
So, there is something a little more sinister going on here. Still
investigating...
