I was told that I can have the Model M keyboard if I can replace it with another keyboard that will work with a IBM Display Terminal (PN: 66G1725). I tried just plugging in a PS2 keyboard but that didn't work. The keyboard looks like it's plugged into an RJ45 jack. Someone help!

You normally can't hotswap a PS/2 keyboard. If you didn't try it with the terminal off and the keyboard plugged in before turning it on, try that.
Don't think those supported mice, but if they did could be a port for that or something else entirely...

I'm under the impression that you need the specific model of keyboard shipped with the terminal for it to work properly, if your terminal predates Set 3 protocol. IBM made a large variety of terminals and different keyboards to go with them. So if you were to acquire that Model M, you might just need to replace it with another identical Model M.

Precisely why Orihalcon, standing on the shoulders of Soarer, has given the world such an extraordinary set of tools.

If this is a terminal Model M, I scarcely think it would be worth the expense to purchase one from Orihalcon.

Whatever. For slightly less than the price of an Orihalcon, you can build:

Note that it has got a PS/2 port on it, so it postdates set 3. Even if that port isn't used for a keyboard.
Even if predates it, there's only a few variations of the terminal boards (two? three?), and there were/are aftermarket versions.
But if the ps/2 port is enabled for keyboard use all that's moot. If it's not I'd be curious why it's there.

Are we sure that is the PS/2 port? Aren't there other applications of the 6-pin Mini-DIN plug elsewhere? :D

So I'm hearing that I'll have to wait till the equipment gets retired and should just buy one.
