Notes The IBM PC-AT was the first upgrade from the basic PC architecture introduced in 1981 (the XT expanded storage options, but not the processor, bus, chipset, etc.) The first ATs were released with a conservative 6 MHz processor which was quickly upgraded to 8 MHz. The BIOS allowed for the definition of aftermarket hard drives. The AT also introduced the 1.2 MB high-density 5.25" floppy drive which became an industry standard until the advent of 3.5" disk drives.
Related Items in Collection Other IBMs and compatibles including Columbia VP, Compaq Portable, IBM PC and IBM PC Convertible
Related Items Wanted IBM EGA monitor and card.


The IBM PC AT was IBM's second generation PC (if you consider the XT an extension of the original PC). It was introduced in 1984 and included several "new" features such as a 6 MHz Intel 80286 processor, a 1.2MB 5.25" floppy drive and an improved keyboard. The typical AT sold with a 20 or 30 MB hard drive and 512K of RAM.

The CMI Hard Drive

The IBM AT in my collection is one of the most pristine ones I've ever seen. It is immaculate inside and out and even has the original Computer Memories Inc. hard drive (there are very few of these that didn't fail early in their lives.)

The interior of the IBM PC AT

The rear of the unit shows the slot ports as well as the lack of a cassette port.

Rear view of the IBM PC AT without the trim cover in place

With the trim plate in place the rear view is cleaned up considerably.

IBM took an oddball route to adding RAM to the AT. To conserve money and motherboard space they piggybacked RAM chips on the 512K version of the board.

Oddball IBM PC AT RAM

In addition, this AT has all of the original documentation, the original plastic "trim plate" that cleaned up the appearance of the back of the machine and even the original IBM logo keys to lock and unlock the case and keyboard.

The IBM PC AT Accessories

The machine also came with an early version of Microsoft Word and a very early Microsoft Mouse.

I still have an early version m/b in my cupboard, and also was able to setup a 720K 3 1/2 floppy which worked fine however the ROM BIOS did not allow 1.44MB 3 1/2 disks which was shame, I also was able to install/run Windows 3.11 on it and seemed run pretty well. I had a 2MB ISA based 2TheMax Video card in the system as well.. and expanded the Harddrive to something quite large .. so far back now .. in the end I dropped a 386DX40 m/b into the case and the existing m/b went into cupboard and has been there since 1996... I have tested it and It seems to still work however I have no controllers or the expanded memory card which is a shame... but it powers up with 512K..

I'm looking at the dram dips in my Ibm Pc At. I really don't know how big they are. I'm looking at 4 banks of 8 drams. I wonder if I can replace the drams with ones that hold more data. Is there a reason why the drams must be a certain size. If so what is the size? what is the reason? If the banks were larger, managers and extenders like Himem and Emm286 and Mscdex and PharLap etc, should use it. Do I need to hunt down an Isa card with memory on it, to get the thrill?

You would never get XP to run on an old vintage machine such as this, not unless you ripped out the guts and forced an ATX board in it. And why would you want to do that?! Updating or flashing your bios all depends on the machine model and motherboard type. The older machines cannot be flashed, so if it is one of those you are stuck with your chinese characters. Search the net once you know your machine model.

I have one of these ATs and it's a real classic. Just fitted a single speed CDROM just for the fun of it! 20mb Mitsubishi MR522-M40 hard drive is in it. Still working 100%. Fitted VGA card in it as no EGA screen anymore, but now looking to add some XMS memory via an ISA upgrade board, when I find one.

Also, the PSU is not original so I am seeking one of those too to complete things.

Most ATs must have seen the scrap heap by now, so it's nice to see some are being preserved!

Hopefully you still have the original documentation and software for your AT, John. If you boot with the Diagnostics disk you can reset the system options so that the machine will recognize the hard drive.

You've also probably got a dead CMOS battery (usually attached to the inside of the machine by velcro and plugged into the motherboard.)

Please email me directly if you have trouble locating the disk.

IBM model 5170 PC/AT has been working for 20 yrs - my Dad plays Cribbage King on it, but now goes to IBM Basic on boot - 162 error, System options not set; run SETUP; press F1 to resume. F1 goes to IBM Basic. Does anyone know: 1. the command to exit from Basic or 2. How to run the Setup utility? Make my Dad happy. Thanks.

Hi, I have an IBM 5170, and need a 5 1/4 BIOS setup floppy for it (the batteries died, and the original disk is no longer around). I was wondering if you had one around, and could make a copy. I would be willing to compensate you for your trouble.

Thanks, Peter Hogan PHoganDive@aol.com
