Remember when 4MB physical was a BIG system?

The most common cause of random errors in my experience is flaky memory.
And the boot-rom RAM tests don't do a decent job of testing anything.
Refresh my memory: is the RAM in the 3/50 socketed or soldered in?  It's
been a long time since I saw one.  If it's socketed, you might want to
try another set of memory, or at very least remove/re-insert what you
have.
