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.

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 (http://geekhack.org/index.php?topic=50437.0) 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 :p

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.
