The last piece of the puzzle... I now have everything to put a floppy on my 11/23+ except the physical floppy drive.
I've done a lot of reading and I could use an RX-50 dual 5.25 drive, or a TEAC 55-GFR 5.25 drive.
Right now I'm thinking of buying two 55-GFR's, one in the Windows box and one connected to the RQDX3.
The 3.5" drives are apparently usable with a custom breakout board like this one:

And that page (and links) have lots of useful info. There is even a mini-breakout board:

But the one question I can't find an answer to is:
Can a 3.5" PC drive be used with the RQDXE (M9058.) breakout board, or is additional circuitry still required (and if so, what)?
I plugged one in for an experiment with the PC_standard "twisted" cable, and the RQDX3 doesn't know it's even attached. (yes, I hooked up power too)
Anyone have experience with this combo?
thanks.
Edit: I found the schematic for hooking up a floppy to the RQDX3 directly. It can handle a 3.5" (as an RX33) but still doesn't say what the RQDXE (M9058.) wiring is. I can dig out the M9058 schematic too, and see what comes out of it on its 34 pin header. Probably just need to tweak a line or two. Hopefully.
