KeyTronic Magnetic Reed Keypad

I came across this little KeyTronic magnetic reed switch board:

This one was easy to hook up - no on-board controller components, just the key matrix connected to a 16 pin socket - so straight to the Teensy:

I don't know what this board came from, but given the "4 AXIS" key it might have been a 4 axis milling machine of some sort.

I've programmed the keys to the letters and numbers as they are on the board and set the other keys to various nav cluster keys for now. I'm not really sure exactly what I'm going to do with it, but it's just kind of a neat little board and I really like the blue keycaps - too bad it's not a full set!

Damn, where do you keep finding these? KT MR isn't exactly common xD .

Looks lovely. Do you have any idea what the half-alphabet is for on the pad?

Yeah really. In five years I havn't come across one.

Hows it feel?

It is damn handsome, but if I might postulate another possible origin...
TID often stands for Thermionic Detector, used inf Gas Chromatography.
TLC stands for Thin Layer Chromatography.
And CPC often stand for Centrifugal Partition Chromatography.
I dare say this came from some kind of Laboratory Computer/Science Equipment.
Possibly a Mass Spectrometer.

Sounds about 100% right on.
