After years of searching, I have found a source for some rare parts to restore my rare Sol-20 microcomputer. It is in perfect operating condition except for the keyboard. The Sol keyboard used foam pad contacts, the pads decompose after about 20 years and the keyboard stops working. A fellow Sol owner located some spare pads for me, for only $5 yay!
I built my Sol-20 from a kit in 1975, it took me weeks to assemble it, it was the first computer I owned. I couldn't afford the fancy (and expensive) Helios 8" disk drives or 3rd party drives like the 5" Northstar system. But I could afford a few gadgets, like a 300baud acoustic coupler and a GraphicAdd card. I did a few nice art projects on my Sol, I'm dying to get the machine back up and running, and see if I can still read my 20+ year old data tapes.
Update: My parts source informs me the parts he found are the wrong type and will not work. So I am still searching for some pads.
Update August 29, 2007: A generous donor supplied me with the correct pads and my Sol is now restored to working condition. You can view the results here.
