I'll send you a private email as well.

Good :-)

Okay, thats what I thought, but wasn't sure.

Oh I see. Okay, this computer is of a caliber, and old enough, so that
MOS memory wasn't taken for granted, like it is now. This would be like
some of my old audio equipment that boasts of its transistors :-)

Oh, I didn't know that. Do you know of any pictures on-line?

I have been kicking around the idea of buying a rack, actaully. Does
the BA213 take anything special to convert to rackmount? Does it use a
different bezel, or no bezel at all? I figured if I did buy a rack, I
would put the 3400 in as well.
