the TS05 is a straight-up Cipher F880, and the TSV05 controller card
is a pretty straightforward QBUS Pertec controller (I seem to remember
hearing it was a rebadged Dilog design, but I wouldn't swear to it).
It's register-compatible with the TS11 controller, with I think a few
enhancements to it.

bootable 9-tracks, but I don't know if they're coming. I forgot to
specify 1600 BPI; that would be ideal. The drive theoretically
does 800, but I've never tried it, and it doesn't support the
non-standard 3200 BPI that some of the real F880s did.

if you don't need any storage. A decent digital scope would go
a long way.

theory, I could run XXDP, but it's hard to do when the tape
drive won't run. I could probably load it on a Zip disk from
Simh and run it from the SCSI card, but that's adding another
layer of complexity (and the need for a card to sit next to
the SCSI card in the 4x4 serpentine backplane, so I'd have to
pull pretty much all the cards out of my VAX... still, could
be done). I don't think it would reveal much beyond "doesn't
work", though, since most of the drive-specific diagnostics
are built into the drive; it actually has a pretty full set
of diagnostic tests as well as full diagnostic procedures in
the service manual (most of which end with "replace this big
chunk of the drive", which was probably more helpful 25 years
ago than it is now).

(or parts) responsible on my own time. It's always just the
inertia of getting it done, and I figure it could be a fun
project for a weekend. :-)
