More details from that silvery sticker: "TOP ASSY TC0210201-FSH" "S/N 93395" "Sub ASSY C3987 C" Hmmm, that Top Assy number has TC02 in it Tim. Also, when looking at the board from the component side up, edge fingers downward, there is a male 26-pin header at top left and a male 20-pin header at top right. In top center is a 4-position DIP switch (SW1) and a single LED (CR1). Just to left of center and downward there are SW2 and SW3 which are both 10-position DIP switches. "C3987" is on a small bar coded sticker under the left-hand 50-pin header. With that TC02 in the Top Assy number would that mean this is indeed a TC02 tape I/F as you figured? If so what tape drive model(s) should I be looking for? Very quick peeking done: The single 50-conductor ribbon cable coming out of the "UDC11" goes to three mass storage units: the 5.25" floppy, the tape drive (it's a Syquest) and a full hight 5.25" hard drive made by, [what was that now? Dang lousy memory...) I think "Vector". Never heard of 'em. Gotta pull the tape and HD units out of the box and write the model numbers down. Anyway, the UDC11 is made by Andromeda Systems. UDC probably means in this case 'Universal Drive (or Device) Controller' since all of the storage devices hang off of it. Okay, anybody have any data on this Andromeda UDC11 module? I used the TU58 reference mostly as an example to give the relative size of the tape cartridge. It does look like a DC100-size would fit in the Syquest tape drive like what I use in my HP9825. Anyway, the Syquest name ought to be recognizable to some people as to the tape type. --Chris -- -- Christian Fandt, Electronic/Electrical Historian Jamestown, NY USA Member of Antique Wireless Association URL: http://www.ggw.org/freenet/a/awa/

Years ago I had heard of them, seen advertising and magazine articles, etc. But they're still going! They have several Q-bus items and card cages. And they *still* have the (U)DC11 in their catalog! That's my type of company. Like me, they are still working at the Trailing Edge of Technology. :-) Cool! Thanks for the wake up, Tim.

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. --Chris -- -- Christian Fandt, Electronic/Electrical Historian Jamestown, NY USA Member of Antique Wireless Association URL: http://www.ggw.org/freenet/a/awa/
