This looks familiar. My old man works for IBM and from 1986 until about 1992 I had an XT 370 sitting in my living room. Very similar to this but had a 10 MB hard drive, was only capable of a 4 color CGA, This one came with 128k ram but we had an expansion card to bring it to 640k. It must have weighed 80lbs.

We also had a 2800bps modem connected to it with a receptacle for the phone hand set, complete with a touch tone generator attached to the mouth piece to enable IBM dial-in.

In 91 we added a PS/2 mod 60 laptop and PS/2 Mod 80 to the collection. All running OS/2, very expensive and very close to useless.

I forgot all about these things! These were poor sellers at best due to their incompatibility with full height cards (as Mr. Powell stated below). We used to leave most (if not ALL) of the case screws out and 'adjust' the cover to accomodate them! Just like the AT, you need a setup disk to get into the BIOS settings since the BIOS does not have the software built into it.

I worked for an IBM dealer from '84 to '87. When the XT-286 came out, we had problems with a lot of the expansion cards. The AST Rampage for example was a 'full height' card designed for the 'new' PC-AT machines. Because they'd squeezed the AT motherboard into an XT chassis, they Rampage's were about 1/4" too tall to fit. We had to quite literally use a plane to take off as much of the top of the Rampage's PCB as possible to make it fit!!
