The C64 is not used to run the shop. It is used to control a drive-shaft balancing machine.

The article talks about "transferring 25 years of records" but that's not what's going on at all. It's just acting as a microprocessor. Also, the computer was programmed in 1990.

What's really surprising here is that the disk drive is still operating.

Interesting to know how it works - a variac is used to manually control motor speed, I guess maybe the C=64 has a speed and vibration sensor somehow.

The article is from 2016, this video from 2018 shows it was still running then:

Looks more like a Commodore 128, but it's hard to tell under all those layers of...yuck.

No, that’s very definitely a C64C, which was released in 1986.. But kudos to its little capacitors hanging on for so long ;)

Huh. By that time I was on my last C64 (original case) and was busy accessorizing it; I had no idea the C64C even existed.
