Depending on the memory board, the 72-pin simms could be. 30-pin simms on

You might try cleaning the contacts on the simms with IPA before you try
swapping them though. I found that 9 times out of 10 that would take care
of things. I still clean memory module contacts for this reason, and it
really does make systems more reliable. Even brand new modules can have
dirt and oils on their contacts.
I've just hacked away at the Dallas RTC chip
and grafted a new battery
onto the top - I'll know in a moment if it works...
Well, it's promising on the battery front, but then the setup floppy
(which was in the machine when I found it) went bad. I wrote a new one
from a downloaded image, but then the machine suddenly coughed up a
memory error during a power cycle. Maybe it's cursed.
If they're just plain 'ol 72-pin simms, I *may* have a generic x86 PC
which uses them, and which I can borrow from. I'll try reseating what's
in there first though, just to be sure.
