Part of the QA procedure for the MechBoard64’s (link) includes testing the keyboards in a real Commodore 64. Doing it this way calls for a lot of power cycles, cartridge swaps for testing keys, plugging and unplugging of the keyboards etc. I therefore use a motherboard that is not too precious to me. However, these machines eventually die and I was therefore on a quest for a new machine. During the hunt, I accidently stumbled across a machine that I thought would suit the purpose perfectly: yellowed case, broken keycap stems, missing keycaps, modified motherboard, missing SID etc. This was all based on the asking price… However, when I got the machine it turned out to be an Assy 250469 Rev. 3 machine in absolutely mint condition!! As in really perfect condition. And it also had a PCB color that I did not have in my collection yet! No yellowing, perfect case, no hardware modifications, all the right chips were soldered directly to the motherboard and it even had a very nice metal RF shield.
Here are some images of the machine.
So I’m still looking for a machine that I can use for my tests as this baby is going to be stored and kept as part of my collection! More images of the machines can be found here (link).
