I have some TK50's as well. They really are not that bad, the key
problem with them is the bearings in the two capstans: They're old, oil
has dried out, and as a result they drag on the tapes. Plus one of them

Well, they're 10 years older than your Windows 95 floppy so sort of. I
still have some working RX50's here but they are a bit fickle. That's a
big reason why I went to TK70's, more reliable.

There is. What's in my floppy pile here:

Micro RSTS 2.1 20 floppy disks
Ultrix 11 2.0 30 floppy disks
