We had two 6809 systems at the high school I attended. One for the computer classes (math department, not business) and one to run the school, with software written by the computer teacher. Fortunately my brother worked at the computer store, owned by Slim and Maeve. He supplied me with enough technical info to be.... uh... a teenager. If you background tasked compiling endlessly looping Pascal programs on one or enough terminals, eventually you could kernel panic the machine. It always came up on terminal 0 logged in as the superuser. Change my own user's permissions, edit the system history file, logout, and AWAY WE GO! I guess I was a VERY primitive form of 1337 h4x0r... Thanks for the mention of SWTPC Keith, and the walk down memory lane :) I was a AVID SWTPC computer user “back in the day”.

If you still have them I can definitely give them a good home. Please get in touch.

I could be wrong, though. Matthias — given the vintage of the hour meter, I’m guessing it actually has a timing motor with a governor and geartrain and it doesn’t rely on 60Hz AC.

OK, now you already got the idea: take a microcontroller, make it toggle a pin with say 600Hz, hook it up to standard 110V/5V transformer in reverse direction, hook it up to the meter, and you're down to 3.5 month :) m about the hour meter:
