Title: Identify this IBM terminal keyboard
Post by: blueSmoke on Thu, 17 April 2014, 01:43:39: I was looking to buy a Model-F-122 and chop off the numpad and make it a tenkeyless, but this popped up.

Definitely not a model M/F. Looks like a cherry like switch, cant be alps. The seller is confused by the model number, but the actual model is definitely in one of the photos.

I would love to buy it for the case and may be do a tenkeyless mode from a M/F to fit this case.

Anybody knows what is that blue switch and make/model of keyboard?

According to the Deskthority wiki, it says it is manufactured by micro switch.

The 104-key Model Fs are pretty hard to come by. They are also kind of big (about the width of a 101-key Model M) which sort of defeats the point of having a tenkeyless :D

Seems a shame.

I love the dedicated arrows and 6-pack, but wouldn't an F AT serve your purpose with simplicity?

I've thought about this as well, but when reading through the threads of the people making new controllers for F, there seemed to be a lot going on on the pcb concerning the traces that was fairly precise. Thought that hacking up that PCB, even if you managed to wire the broken traces up, would throw everything out of whack.

On top of that, seems a shame to do to a F-122. You might be better off getting an AT and changing it to a tenkeyless layout.

Post by: maatmouse on Sat, 19 April 2014, 13:46:13: Looks like an old IBM Model F (one of the terminal keyboards). Definitely an IBM. The layout and the colour give it away. The connector is also a clue. Usually these have a ps/2 connector on them.

except its clearly not a buckling spring board....and no F had PS2
