Looks like an IBM model M, but the wear on this one seems bad

All of the special keys didn't work with Soarer's converter because they were sending scancodes above 0x80: Their mappings (See cs2_9xcode(uint8_t code) in ibmpc_usb.c and the cs2 part of unimap_trans.h): Break - Pause/Break Print/Send - PrintScreen Funct - Left Alt Ins/Repl - Insert Del - Delete (d...

Since Soarer's converter didn't work for a lot of the special keys, I changed the TMK software a bit to convert the NCR 4950 on a Teensy 2.0:

Aw that's a bummer. I guess I will have to go with TMK or something..

I'm sorry for asking this but it's been a while since the creation of this project, and source code is still not available. Is there a reason why it is still not released? My problem is just that my keyboard is sending custom codes which are not in the fixed translation sets - so without the source ...

Okay after trying a few things out the mod worked for me. just change out all the jumpers. I had a pcb version with no voltage regulators. My cable looked like a phone cable with 4 conductors and had different color order than consideringquiet's cable. But after the AT conversion, TheInverseKey's pi...

Worked for me, thanks a lot for the instructions! Also I didn't have C3 desoldered and it still works.
