Wow, these devices apparently had an amazing quality. The interviewee runs a campsite and bought an Atari ST in 1985 because it had more RAM than a PC, and he also had to write the management software himself, which he still has in daily use (starts it in spring and shuts it down in october). He didn't say which language/database he used for implementation; any ideas?

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!
