I still have the TK50, but I wonder if my TK50 drive is operational...
I can't remember how much CPU diagnostics is on that tape. My
recollection is that it's more about testing peripherials, but there
should be some basic tests in there as far as I remember.

I'm pretty sure there was a TK-50 diagnostics tape (I never
had one, but
saw the DEC
techs use them). There may also have been floppies in the very early
MicroVAX
days. Brief background: Real VAXes had real
diagnostics. MicroVAXes had
diagnostic$
There was a set of CPU diags on floppies that came
with our first 780.
I think
we also had a set of additional diagnostics on 9-track tape if the CPU
was fully operational.
That won't help. This would be the diagnostic supervisor, which do not
run on MicroVAXen.
