Hello,
I was just wondering, if you know where I could find TU58 rubber
rollers. I know one VAX 11/730 in our university's cellar, that
could hardly boot because of worn rollers. I could perhaps repair
it' if I had the rollers.

I would replace the tu58 with a laptop running linux and the the tu-58
emulator. That's what I do with my 730. Works great.

Err... A laptop is a lot harder to maintain than a TU58.
What _I'd_ do is find the diameter of the original roller, use a suitable
O-ring and either glue it to the original hub, or more probably turn down
the original hub, make a sleve to fit over it with a groove for the
O-ring, and put it on with a bit of 'high strength retainer'. This
assumes the entire hub is difficult to reproduce, say because it includes
a tachometer disk.

The usual fix for a TU-58 is to get some Tygon tubing from the local
hardware store (the stuff that's about 0.500"), cut a sliver that's about
as long as the aluminum hub is tall, and put it on the hub (after removing
the gooey rubber roller, naturally).
I've done this on several drives. You can find specific dimensions and
probably more specific directions for this procedure in the list archives,
but that's the nub of it.
