Identify and Appreciate

I just bought this IBM terminal board. I couldn't figure out what model it was, looking to get some help here. The quality of the board is great, everything is either hard plastic or metal.





The innards





Back



The feet



And the knob for them



And the massive terminal connector

Looks like a Model F 5291.

Colloquially known as the IBM "Bigfoot" terminal keyboard. It's the same odd layout as the XT keyboard that came with the original IBM Personal Computer 5150, but in a bigger case.

Can identify this is a Model F, it's the same layout as the XT one I used which Techno Trousers mentioned.

bigfoot, pretty pointless as nobody has a converter yet made for it

Soarer's controller works with it.

On second thought, that's not quite a 5291. That has a 15 pin connector and this has a 25 pin one... hmmm.. most interesting. Can you take more shots of the controller? I Think this may be a rarer variant for more secure purposes.

Yeah, that's considerably different from a 5291 keyboard controller. The mystery deepens

Very interesting find. The layout looks like that of the System/23 Datamaster rather than that of the 5291, but I never have heard of a free-standing keyboard with the Datamaster layout... See:

After opening up a Model F, you realize that virtually all other keyboards are plastic junk.
