Kevin-
Have you found something to soothe the classic computer beast within?
I have an unfinished Sol motherboard & documentation available.
The motherboard actually appears to have been finished, when some
previous owner decided to unsolder the connectors from the board;
however, most all the IC sockets are still in place.
Since the docs include theory-of-operation, you should be able to
make a working Sol out of this- except, of course, it does not
come with a case, keyboard, or power supply.
Interested?
regards,
