I remember the DEC-20 at Ohio State. It had a TU77 tape drive. This was back in the days of paper Operator Logs. One day, it went like this: 09:23 TU77 catches fire 09:24 TU77 puts itself out 09:35 TU77 won't load tapes, Called Field Service. When they called, the convo went something like, "you have a TU77 on fire? We'll be right out." No additional questions. FS Engineer comes out with one satchel, opens the tape drive, pops out one board, pops in a replacement from his satchel, and the drive comes back to life. Clearly not his first barbeque. -ethan
