The keyboard looks like a variant of the keyboard on display at the Victoria and Albert Museum in London right now attached to the Apple-1. It was a giant pain to get it working correctly. I didn't have good schematics so had to create a ton of notes and pseudo schematics using a ohm meter, scope and logic analyzer. It was very satisfying to get it working :-)
The V&A keyboard is KTC-065-01466. There is a story on the sol-20 prototype proms, if I recall correctly, in the book "Fire in the valley".
