1/2: The revived #SOL20 is almost done. I've added a #ProcessorTechnology 32KRA DRAM memory card (one of the last, rarest, and best designed of their S-100 cards). Of the original 32x 4108 DRAM chips in it, only 3 were still working. But since every bank should have identical chips, I'll be replacing them all with 4116s (150ns). For now I could populate only one bank, but new chips are on the way. (Continued)
2: ...I'm having new wooden side panels made, the PSU is fully rebuilt, and now only the keyboard and memory card are needing restoration, besides the iron chassis, which I'll tackle this weekend. @homecomputermuseum #SOL20 #ProcessorTechnology #SolTerminalComputer #FirstHomeComputer @homecompmuseum

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.
