Cool. Thanks for sharing that!
Also, when
the tapes arrive, are there recommendations in case their
drive belts are gone?
You can 3D-print replacements.
Use Innoflex filament, 100% fill-in and the following OpenScad formula :
module ring(d1,d2,w)
{
difference()
{ cylinder( w, d1/2, d1/2, $fn=230);
cylinder( w, d2/2, d2/2, $fn=230);
}
}
ring(38.2,35,6); // TU60 Dectape-II Already 2 TU60 have been repaired with the above.
TU60 are direct-drive digital cassettes.

The TU58 uses DC100 cartridges.

I had a boss who recycled some DEC TU58 for our HP 4951A serial
analyzer. It can format cassettes, the TU58 cannot, so it's a
one-way-trip.
