I help keep one running. So it is possible. :-) We replaced all of the capacitors in the power supply after the machine was purchased. Cheap insurance.
The drives have been trouble free, but the control flakes out once in a while. Usually it just stops and forgets what it is doing The control is an antique and it should be replaced, but the owner is too cheap to do that ( I have offered ). I have a PC rigged up to load programs into the GE control so the tape drive is no longer required. On the machine I help maintain, the feed drives are huge and replacing them would be very expensive. Plus he has spare drives. The machine is a very big lathe - I think it weighs about 35,000 lbs. It is massive.
