anyone here help? If it is the onboard RAM, is ther anyway I can
bypass it? The
Classic will boot and run fine, except 95% of the programs I open will
pop up
with an address error System bomb.

First thing that comes to mind is a virus. Yes, v-i-r-u-s. The nVir
could do funny things sometimes. You've gone through so much testing
that I have no better candidate for the moment. Get Disinfectant 3.7.1
(on another machine of course) and run it from a locked disk after
booting from ROM, at least to exclude this possibility. If you don't
have the Disinfectant option, try to get a known-clean Utilities disk
of any flavour of 6 or 7 you feel fit, lock it and either boot from it
or the ROM disk and format this HD. Nuke and pave. That should clean
everything off (if I am not right, correct me please). Check your
floppies for viruses that may have spread from any floppy or from the
new HD. Good you have at least one boot volume that can't get infected,
the ROM disk.
I'd go that way because a virus attack would explain every symptom your
system shows. Bad onboard RAM would explain part of it, but with that
I'd expect system crashes at any system activity at least as often as
bombs when starting an application. The RAM test is good, and AFAIK the
RAM soldered to the mobo can't be bypassed, so the only way to check
this is swapping the mainboard with a known-good one. You tried to
exclude other reasons for erratic behaviour of the mainboard by
thoroughly cleaning it, but some exotic things like carbon fiber or
iron file dust contamination are practically untreatable by every
cleaning method below dishwasher-level.
I had two instances of nVir attacks, one in 1989 and one a year or so
ago when I bought my umpteenth compact that hadn't been in use for more
than ten years, and it had the virus on the HD. Disinfectant is your
friend, and it's free.
So have fun resolving this tricky problem and keep us posted!
