Up for sale is one Commodore 128 computer with power supply, fully tested and working. This computer has been thoroughly cleaned, repaired, and tested. The 8580 SID chip is fully working, as are both the low resolution (C64, 40-column) and high resolution (80-column RGBI digital) video outputs. The only incorrect part on this computer is that it has a second left arrow instead of the right arrow key in the top row of keys. It passes the C128 diagnostic cartridge test suite with no errors, as shown.
