AMPEX 220 Converter

Hi,

I just got an AMPEX 220 keyboard and it's a clone of the DEC LK 201. Therefore, I was wondering if there is a converter that is able to convert it to usb via a teensy.

Thanks

What does the back label say? I have a very similar board (without the awesome caps) that sends ANSI key values via asynch serial.

Good old trusty kbdbabel.org has one. It translates it to PS/2 not USB and controller is 8051 though.

(its sourceforge repo has been unuseful now so I mirrored it in github.)

The keyboard is well docmented here if you are willing to work on this yourself.

I will get a picture of it later.

Thanks for the information, hopefully I can bring this board back.
