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?
There is a tape drive and 5.25" hard drive in
the MicroPDP. The tape
looks like it takes a TU58-size tape (could it be a TU58?) Also, there's
a third-party dual width card with light blue ejector handles with
"UDC11" stamped in white letters on one. Don't know where the ribbon
cable goes that's connected to it. I'll take the BA11 chassis out and
peek inside tonight and report what I find on these questions.
The BA23 was originally marketed with an 5.25" RD series drive and an
RX50 dual 5.25" floppy drive. Later, for the MicroVAX/VaxStationI/II/IIRC
system, the RX50 was replaced by a TK50. There was also a configuration
with an RX33 instead of either the RX50 or TK50.
A TU58 type tape drive sounds very strange for the BA23... maybe it
was packaged by someone else? (Would the single TU58 tape drive of
a Vax-11/730 be adaptable to the skids of a BA23 drive bay?)
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.
