From the Commodore USA Facebook page: "This C64C used by a small auto repair shop for balancing driveshafts has been working non-stop for over 25 years! And despite surviving a flood it is still going..."
This reminded me of an article I wrote for Wired in 2000 about people who used old computers.
"Just how much horsepower do you need to read and reply to messages on the Internet?" asks Maurice Randall, a Commodore loyalist and owner of a one-man car-repair shop in Charlotte, Michigan. Randall, who wrote and now sells the first fax software for the Commodore 64, has just finished coding the machine's inaugural Web browser. He uses his C64 for everything from invoices to faxes to displaying automotive diagnostics. "There hasn't been anything made in the last three or four years that's necessary in computer hardware," he says. "I wouldn't be able to do anything more with a new PC than I'm doing with my 64."
