So I just got one of the IBM 611288 keyboards from the Ebay auction. (Incidentally, this is the first linear I've actually liked!)
I've been googling furiously to figure out the pinout for the 9-pin connector on this thing to wire up a Teensy, and I wanted to keep the old cable while I'm at it. The closest I could get is this: the page on the 4704 converter (https://geekhack.org/index.php?topic=50437.msg1193047#msg1193047) and the page on the keyboard itself (https://geekhack.org/index.php?topic=62628.0), so I at least have an idea how to do it internally if push comes to shove.
Problem is, I'm still not so confident on the pinouts for the connector itself. This is a 9-pin D-sub, correct? If that's the case, I know the ground is position 5 and...that's about it. There's only 4 wires on this thing, and the ground leaves 3, but Soarer's diagram had a LOT more wired directly to the Teensy board. (To make a point, I'm not even sure which of the remaining ones would correspond to the VCC pinout...)
Can the 4 pins still do the trick via external connector --> Teensy, or does doing it externally not work?
EDIT: fixing grammar, etc.

Soarer's Controller can do it (https://geekhack.org/index.php?topic=50437.msg1193047#msg1193047) :)

Soarer's converter maps weird versions of the XT/AT protocol to USB.
Soarer's Controller scans the matrix directly; it replaces the processor inside the keyboard.

Oh no, does that mean that if you flash your teensy with the wrong thing, it will not work?
I think I've flashed my Atmegas with Soarer's Controller 1.20 rather than Soarer's Converter 1.10, resulting in none of my Atmegas working with my Model Fs. (Whereas my teensies work fine with my Model Fs.)
