IMSAI 8080


Some pictures documenting the restoration of an IMSAI 8080

After removal and cleaning of the front panel. Everything looks in very good condition although some of those capacitors might need replacing after 38 years








After complete disassembly, the reconstruction can begin. Replacement motherboard screws were needed due to the age (3/4" 6-32 nylon with 6-32 1/4" alu spacers)
