I once was asked if I would like to pick up a #C64 that had been found from a basement of a newly bought house. I agreed to this, but failed to arrange the pickup. Despite this, I later was handed the #commodore duffel bag after an event we both attended – A proof that inactivity is in fact awarded eventually.
The system had been stored in the basement for number of years and the status of it was unknown. I took to the gear to the office and inspected the system and found out that 9-key had been sheared off by the stem, likely due to being hit by the famously heavy power brick. Opening the system up revealed no major visual issues such as excessive rust or similar. I also measured the PSU for overvoltage (high, but not yet alarming - I later obtained a replacement aftermarket PSU). @dist was happy to help with the broken key stem by #3dprinting a couple of new ones. Only a moderate amount of sanding was needed to make the stem run smoothly.
The included datassette still had a game tape inside it - which presumably had been sitting there for decades. I rewinded the tape, typed load and proceeded to hit press play on tape. The game loaded without a hitch. It turned out to be Battleships, which I immediately proceeded to test the joystick with. Unsurprisingly some directions in the Quickshot II joystick were dead, a very common mode of failure.
Later I also replaced the raspy 6581 #SID chip with FPGASID and added a #1541ultimate II+ cartridge from Gideon’s Logic BV, and brought over a vintage TAC-2 and a SpeedLink Competition Pro reproduction joysticks. The picture in my profile banner is of this office C64 system. #retrocomputing
