Apropos long-use machines from the 80's, I have in my collection a system that was for 40-years used as the primary database for logging trips and fuel consumption for a motorcycle club .. a few hundred or so riders, every weekend, logging their details and distances and consumption rates .. it was sent to me after a members grandson finally said "lets replace this with an android tablet" .. well, now this machine, which was running for 40 years, is a museum piece. ;0

Still works great!
