PC question - test-drb@ccmp.vtda.org

This all sounds like a lot of trouble.

They all had labels on the front you know. The AT had "IBM Personal Computer
AT",
the XT similar with "XT". The only one that looks indistinct was the
original PC which just said "IBM Personal Computer".

Failing that they had labels on the back. The PC was model 5150, the XT
model 5160 and the AT model 5170 as I recall.

 If they are IBM boxes, then the shape will give that
away.  If the box has a
...
 sloped front, then it's an XT.  If the floppy is a
full-height drive, it's
an XT, and if you look inside it will be really obvious, in that the XT
motherboard is confined to the area to the left (as you face the front of
the box) of the power supply.  Most obvious of all, of course, is the fact
that the XT had no 16-bit slots in the motherboard.  XT-types generally had
a floppy controller and a separate hard disk controller.  The AT had a
single controller for both.

Yesterday, at the KS10 move, I came away with two IBM PCs, but I
don't know enough about them to know if they are the AT or XT
models... they both have a 5.25" floppy and a hard drive, and
both have color monitors.

They are both desktop boxes... the monitors were sitting on top
of them.

So, how do I tell...
