This morning I went to a trift store and found an IBM PC that said
"Personal Computer 3270". How rare are these? I've never seen one before.
I have seen AT 3270s but not a PC. This one had a full height hard drive
with IBM logo on it and a full height 5 1/4" floppy drive with IBM's logo.
It had model 5271 marked on the back.
Also a few weeks ago I saw an IBM AT that was marked "Personnal Computer
AT Store Controller". What is it for? I've never heard of one. The owner
said that he had already "modified it" to make it a regular computer.

I have 2 of the 3271's which are essentially 5160 XT with added network
equipment. Anyone interested in buying one or both?
The AT store controller is again another stock machine with options (like an
Impala with extra goodies is called an SS) in that it was made as part of a
point-of-sale system from a 5170 platform. I sold 50 of those two years ago
after I had gutted certain useless (to the average "Joe") cards and made them
into 5170 AT's. Sears in Chicago dumped them for $10 each and I sold them at
roughly $25 each, in no time flat.

Whatever you do, don't throw the 3270 adapters, keyboard adapters or APA
cards (the card that bridges to the display adapter) away. Those are hard
to come by, and we get calls for them on a regular basis.

Yup, that's a POS box. I think the Albertson's grocery chain here in
Oklahoma still use them. At the stroke of midnight every day, all their
registers go offline for about 15 minutes and the managers and cashiers
scream back and forth at each other. That's the first sign that IBMs are in
use.

I'm sure my 3270pc handles a
"better" quality CGA. It just looks
like EGA, thought it was... It was running a version of Norton
Utes and it was just beautiful turquoise blue set and clear
characters.
I'd have to think this was better than CGA, especially since it
took two coupled long cards to run the video...

No, it isn't PGA. (Although most of the chips on the cards are
likely to be PGAs, in IBM custom metal cans, as I recall...)
The IBM 5272, the 3270PC display, was a very nice monitor. I don't
know the pixel resolution, but I'd guess at 800 x 400.
Unfortunately, AFAIK, it only did 8 colours.
The 3270PC display card did TEXT MODES ONLY - it was aimed at
emulating the 3279 terminal. You could buy two add-on cards for it
that went in the slots either side in the motherboard.
1. The PS card. This provided emulation of the Programmed Symbols
option on the 3279. Very nice graphics, but only as a terminal, not
as a PC (although presumably you could have written PC drivers for
it...)
2. The APA card. This provided support of the All Points
Addressable modes of the CGA. These CGA modes were displayed in the
top lefthand corner of the screen. And the only 8 colours reduced
the capability somewhat as well.
It looked very good, but AFAIK IBM never supported it properly.
Pity. But your description of the 3270PC sounds like
you've got only one
of PS and APA, alas.
Hope this helps
Philip.
I've had a 5272 -23 monitor stashed for some time. Was never able to
get it working on an XT trying various standard cards and drivers,
altho it did display jumbled-up color lines so I figured it must be
the driver. IBM wouldn't/couldn't offer me any help.
From the above, it appears that I would need a 3270pc display card
and one of two add-on cards. If I was fortunate enough to find these
would it work on an XT ?

I'm not sure if you could make the 5272 work for run-of-the-mill DOS apps
on an XT, even with the 3270 cards since the functionality they add is
mostly for the 3270 ws emu. There was a fellow who was doing a fix on the
5272 that made it a standard EGA--IIRC it was just a couple desolders and a
few cuts with an X-acto knife. I lost track of him, but you might try
searching Alta Vista for "5272". If I find him again I'll post his info
here.

Let me know what these parts look like and I'll grab them for you if you

a small red shaft sticking out? Looks like a miniture circuit breaker?) Is
the keyboard adapter external or internal? If it's external, then it's
already off the machine but I might be able to find it if you give me a
