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.
