Sol Terminal Color Photo, and PROMs

[Corey Cohen]

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".    

Cheers,
Corey
