Yes it was an ascii keyboard so if it worked, the interface to the Apple-1 is easy. It
just had a lot of bad chips which were soldered in.

Subject: Re: Sol Terminal Color Photo, and PROMs
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

Hey guys,
Does anyone know if any color photos exist of the Sol 'Intelligent Terminal'
that appeared on the cover of Popular Electronics, July 1976? I just
discovered that that Keytronics keyboard I bought on ebay (the one parted
out from a mystery 8080 terminal of some sort) is the same one they used for
the PE cover unit. I found the artwork tonight on
sol20.org for the
original PCB. If I could find a color photo it'd at least be possible to
build a replica of that unit someday.
I was curious too if anyone knew the story behind the four optional PROM ICs
that could be installed on the board. The article only says 'Optional,
write in for details'. Can't find any more info than that anywhere. I
understand Processor Technology sort of dodged around PE's reluctance to
publish any more computer articles, and I'm wondering if the terminal could
be turned into a full blown computer with the aid of those PROMs.
To refresh - this is the keyboard I bought.

Definitely seems to be the same one - just different colors and legends on
the keys themselves.

Thanks Corey!
From what I've read around about this terminal.. PE didn't want to do any more
articles on computers so Processor Tech sort of stripped down what was to become their
Terminal Computer, calling it just a terminal for the article, although apparently the
motherboard design changed to what's in the Sol 20. I'll look for that book.
It's interesting that this first terminal isn't better documented. Or that PE
didn't take one color photo of the first unit.
Was the output on the keyboard you worked on ASCII at least?
