could be thinking too simply for the college years he built them in his
dorm so I'd imagine common off the shelf parts and generally just an IBM
clone. I would think some other similar era computers would also have that
error code.
I started reading another person's post with a similar error on vcfed
forums but I don't think they ever really solved it. There was an attempt
to dump the bios to see what it might be checking (beyond my depth of
knowledge).
I guess that would let you know if it's a bios or other device printing
the error. I assume you've booted it with no addon cards and still see the
message.

Well, I appreciate that people answered my question. I sometimes ask
questions and then proceed to work on it until I figure it out. There is a
THESYS "MULTI/RAM card and that was the card with the password ROM. I
found the dip switch "PW" and turned it off. Problem solved. The Turbo
error #04 is still a mystery, but it does not prevent me from using the
system. I am thinking there's an incorrect but incidental switch setting.
It could be a RAM chip but I have no proof. Chkdsk returns an full 640K.
