My uPDP has an RX50 and an as yet undetermined RD which I have to take out
to see model designation. No time yet, but it is a "Vector" brand. Ever
hear of this company?

Confirm yes or no for me that an RX33 is a 3.5" floppy?

Well, it actually is not a TU58 as there are TU58's on both VAXen sitting
in my garage. I was not sure yet if there were more than one "style" of
case for a TU58. I mentioned TU58 anyway to try to give an idea to folks
what size tape cartidge fits. Bad idea, Chris, bad idea. Go sit in the
corner.... Anyway, the tape drive is a Syquest of some sort. Again, I have
to remove the tape drive to determine the model number.

No cartidge tapes of any sort were with any of the VAX or uPDP stuff; only
three TK50 CompacTapes (sp.?) were with my uVAXII.

So much stuff to go through and resolve questions, so little time
available.... Sigh.
