View Full Version : Ibm pc xt terminal keyboard compatability

September 8th, 2017, 06:44 PM
I have an ibm xt without a keyboard but the only reasonably priced keyboards i can find are terminal keyboards such as the 1386303, 1390636 or 1390766.
I'm wondering if these would work with the xt?

Not directly -- you'd either need to have a set of 3270PC cards to turn the XT into a 3270PC, or use a protocol converter like the AT2XT (possibly with modified firmware) between the keyboard and the PC.

I have an IBM PC/XT Model F keyboard but It's not likely in the price range you're looking for.

I'll look around and if I come across a no name XT keyboard I'll post the details.

The AT2XT converters are really cheap to make and ps2 style AT keyboards are cheap and easy to find. It's probably the cheapest easiest solution.

Shouldn't be too hard to find a cheap keyboard if it doesn't have to be genuine IBM...

It's been a while since I used one, but a google of "ps/2 female to din5 male" gives a lot of results. Can't say how many ps/2 keyboards will work with an XT but it should at least widen the possibilities.

The basic "ps/2 female to din5 male" adapters are intended for AT class stuff. You'll still need the AT2XT converter. There *may* exist a keyboard with a PS/2 connector that can communicate with an XT, but that would likely be expensive.

There are various projects to use terminal keyboards on modern PC's, usually via USB. So you could do that, then get a USB to PS/2 converter and then a AT2XT converter, but this is a real round about way to do things. Another way would be to use the 3270PC hardware in an XT. But this is going to cost more than the original keyboard.

If you want a no name XT/AT (switchable protocol) keyboard I probably have a spare one, but it will probably need restoration.

I found an IBM 4176191 for sale but it uses a 15 pin D Plug. Would it be possible to convert to use with an XT?

I found an IBM 4176191 for sale, but it has a 15pin D-Plug. Could it be converted for use with an XT?
