This is my mid-70s Processor Technology Sol-20 computer with the keyboard disassembled for reconditioning. I finished reconditioning the keyboard and the unit is fully functional. It's in a crate right now as I moved recently. Need to get this unboxed so I can play with it.
The Sol-20 was an 8080 based computer although mine had a newer 8085 cpu running at a blazing 2Mhz. The Sol came with 4KB of memory onboard. Mine has an additional 16K on a S-100 bus card.
It's crazy how much you could do with 16k of memory. Here's a picture of my machine running "Target".
