The lower drive attaches to the BA(1)23 drive sled by the bottom screws. The upper drive attaches to the lower drive by a plate on the left and right side each. The two plates are the front bezels from dead MFM disks. I just drilled holes for the side screws into them. -- tschüß, Jochen

Re: DEC RX02-PA?
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 I think the BA23 was fairly superseded by the S-box when those peripherals hit the market.

The mounting hardware is interesting, was there ever something like that for the BA23? I always wanted to mount a TZ30 and RX33 drive in place of the RX50 drive, was that ever an option?
Re: DEC RX02-PA?
Looked briefly and my suspicion is that it's genuinely an RX02 ... or most of the major guts of one ... repackaged into a much larger and uglier cabinet, LOL. There's a good chance it is what it says it is ... the exposed control board in Pic 2 looks basically identical to that in my (standard cabinet) RX02. You're right though, odd cabinet, never seen it before.

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.

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.
