Original Box Condition:
* Has some tape and worn edges/corners, the cardboard is showing its years. See pictures.

Power Supply:
* Vintage supply was tested under loaded conditions and currently meets voltage/noise requirements.
* After verification, tested it with this system several games and test suites without issue.

I'm a retired Electrical Engineer (25 years with Intel) who has been interested in C64s since my first one in 1983.
All work is done in an ESD safe environment with professional equipment.
I take great care and pride in restoring these old machines to operating like new!Sale includes Commodore 64 Computer and original Box + Power Supply only.
Other peripherals not included. I recommend using a modern C64 power supply, also an S-video cable for best video quality.
I'm happy to make detailed recommendations, feel free to ask!Unit will be well wrapped in ESD safe (pink) bubble wrap for physical and electrical safety during shipping.Please contact me with any questions and I will respond promptly.
Thank you for your consideration!ID:
