So, while very similar to 3178 and 3101 keyboards in many aspects I do think it is different. Maybe some kind of replacement keyboard for the big original 3278/3279 keyboard. Will trace the connections of the cable some day to verify, though. /Mattis > > Cindy >

But as you said that one had a 15 pin dsub. This 25 dsub actually has the missing pins in the righty places compared to the 3279 so I am leaning towards that it in fact is a 3279 compatible keyboard. Will probably trace the lines and compare those with the 3279 KB connector to see if at least ident pins and power pins is in the right places. Then I will just go ahead and try to connect it to the 3279 and see what happens when executing the keyboard test (test 2) of the 3279. /Mattis > > Matt >

Re: Is this IBM keyboard compatible with the IBM 3279?
I was doing field service on 3270 terminals among other things up until 1983 and I never saw a 3278 or 3279 with a keyboard like this, all the ones I recall seeing where an earlier capacitive switch keyboard that is sometimes referred to as the "Beam-spring" switch. That said this ones does seem to have all the right keys in the right place for a 3270 keyboard. The replacement product for the 3279 was announced spring of 1984 so 3279 may have already been out of production when this keyboard was made. Paul.

Is this IBM keyboard compatible with the IBM 3279?
The connector is the correct one. It has four jumpers that could be used for setting one of the keyboard types using the KB ident lines. https://i.imgur.com/PhfvKaV.jpg https://i.imgur.com/VPT38cK.jpg https://i.imgur.com/nN1gtFu.jpg Which terminal was it used for originally? /Mattis
