It's
not but INITIALIZE takes care of that! But be aware that that the
rubber feed wheels in most 85s have long since melted away.
Presumably they can be rebuilt, though. I've got an HP9815 (uses the same
cartridges) tape drive in bits on the bench at the moment, and the
capstan looks/feels good as new. If it wasn't, it doesn't look impossible
to repair it.
If they are anyway similar TU58 suffers the same problem and those are
fairly easy to fix.
