The PDT-11/150 at least have drives that resembles the ones on ebay, but the cabinet is different (if you can even say the PDT-11/150 have a cabinet). No, the ebay listing is still a weird beast, to say the least.

DEC did sell a version of the BA23 that was intended to be used just as an expansion peripherals cabinet. You shouldn't have any problems putting HH devices in BA23 bays (so long as you have the appropriate interfaces to drive them) but you may need i.e. 3.5" to 5.25" bracket to attach to the BA23 sleds, and you'll have (cosmetic) blank space on top after putting a HH device in a FH bay. I imagine you'd have to make a special bracket to mount a TZ30/RX33 over-under in one of the 5.25" bays in the BA23 but it could certainly be done ... No such factory configuration exists AFAIK

I did not know that. It must have been a fairly rare thing? I don't think I've ever seen one photographed.

If it was a salvageable set of RX02s, it would have been nice to have! Too bad he pulled the listing. On Sun, Aug 9, 2015 at 5:06 PM, Pete Turnbull <pete at dunnington.plus.com> wrote: an HH a normally the -- Ben Sinclair ben at bensinclair.com

There is a very simple solution to mount 2 * RX33 floppy drives if you have an old RX50 which no longer works - or you at least can borrow the outer shell from a working RX50. There is sufficient room when 2 * RX33 floppy drives are stuffed into an empty RX50 shell to hold the edge connectors along with a Y power splitter. Then use a few bolts to make the empty shell rigid by attaching the now FULL RX50 shell (naturally with the 2 * RX33 drives inside) to both RX33 drives plus attaching the original black plastic sled to the bottom in its original location. I suggest that you first test everything out to make sure that the connections are working before placing the 2 * RX33 drives inside the empty RX50 shell. Once finished, the 2 * RX33 drives look very much like a dual RX50, but the handles to lock in the floppy media give the situation away on close inspection. ALSO, it seems best to mount both RX33 drives right-side UP. The lower handle works much more easily that way. I still have my dual RX33 set-up in this manner. The only difference is that the cable ends in two edge connectors rather than the header used for the RX50. So it does work. This probably works since the RQDX3 is set to handle the dual RX50, so having 2 * RX33 floppy drives is equivalent. NOTE that the RX33 will work ONLY with the RQDX3, not the RQDX1 or RQDX2. In addition, with the RX33 drive, DEC actually supports the command to perform a Low Level Format which was NEVER possible with the RX50 drive with DEC hardware in a PDP-11 Qbus system. Under RT-11, just FORMAT DU0: As far as 1 * RX33 and a TZ30, I imagine that would also be fairly easy as well, although I don't know how much clearance is available inside the empty RX50 shell for the cable to the TZ30 tape drive. If someone actually attempts to place both the RX33 and the TZ30 inside the RX50 shell, please let us know what happens. Jerome Fine
