Hey guys. Long time troller first time poster  :wave:

Forgive me if this is a total nubz q...  :)  but does anyone have any idea what the hell this connector is?
 I wanna say some sort of serial, but that would be too easy \ don't think so, heh.

Parallel interface that some people are working on, no dice yet. If you do however, get a scope and figure it out, major props to you. :)

Welcome!

It could be this one, judging by the position of the missing pin:



kbdbabel also has a 5291 circuit diagram.

If it's that one, it doesn't actually have a controller inside it, just a bit of decoding logic that allow the host to scan the matrix.

Wow, that was a fast response. Haven't even gone to bed yet (6am EST)
Probably should have mentioned this before, but this is from an ebay auction- which is still live-  http://cgi.ebay.com/IBM-UB-25-Classic-White-Enhanced-Keyboard-Vintage-/160583273724?_trksid=p5197.m7&_trkparms=algo%3DLVI%26itu%3DUCI%26otn%3D4%26po%3DLVI%26ps%3D63%26clkid%3D684125977667557091

I have the same Model F and I thought it was Game Port at first (the connector fits perfectly). However the signalling is different.
