That would be the MDM. And yes, I think it existed for both RX50 and 
TK50, but I've only used the TK50 version myself.

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.

That won't help. This would be the diagnostic supervisor, which do not 
run on MicroVAXen.
