Actually, I do
have an *original* IBM PC. March 82, 48k motherboard
(not the later 64k), SINGLE side 160K floppy, Amdek color monitor.

That sounds about right. I have a second-generation IBM PC, and it can go up
to 256k. I remember being excited that I had the second one, cause the first
had some horrible memory limit and I didn't have the $$$ to shell out for an
AST SixPack or the like. Of which I have several now, of course :)

and three rows of sockets for an additional 48K. this
made it possible to
stuff it with a full 64K of Ram. The second version had 64K chips soldered
and sockets to bring it up to 256K.

I shouldn't be responding to this (I've transferred my
subscription to my home computer) but couldn't resist.
I think the base(A) was 64K and the max(B) was 640K,
apparently because some decision maker didn't understand
the value of powers of 2. Sorry but supporting materials
are not at hand, but I think I can back this up.

JIK someone reads this thread but not the other:
My original receipt (4/2/82) shows I purchased a 48k base unit and
paid $90 for the 16kb upgrade kit.

Amdek's are nice but I have 5 or 6 original green IBM mono monitors out in
storage with my dozen of so PC's and XT's that I ought to put up for sale or
trade sometime while I'm selling off all of these PS/2's I have to find new
homes for. Cash stores much better than computer equipment but if you have
time to tinker with the computers then your outlook is opposite of mine.
Guess I ought to seek new homes for the half dozen Zeniths I have too. But
then what will hold the office trailer down in high winds (grin)
