Rafi keyboard from 1976

Hi,

 

I have a keyboard used in a german made accounting computer from 1976. The keyboard has possibly hall-effect sensors to recognize key presses. Im interested if anyone has seen a similar keyboard? Maybe it can be adapted to the Apple 1?

From what I've read if it

From what I've read if it uses a strobed parallel ASCII output it can be made to work.  Made to work does not necessarily imply "plug right in".  Most likely some kind of adapter cable will need to be made at minimum, and it is possible that some additional logic like inverting signals, etc, may be required to make ti work.  If you've got any kind of specs on the output that will make it easier.  If not you'll need to figure out what the output is in order to figure out what is necessary to make it work on an Apple 1.

There is a 256x8 rom (1702 compatible) that may be used for keycode conversion.
