I came across a large pile of Micropolis 1558 ESDI drives today. No clue
what the owner wants for them. I was wondering if these might be compatible
with an 11/23's RQDX3 controller?

nope. RQDX3 is MFM. Think ST-225.
You'd need an ESDI controller for those.
(and if anyone has one for qbus they don't need, let me know! :-)

The RQDX3 is a MFM controller, so they won't work. However, if you get
ahold of something like a WQESD/04, then you'll have something much better
than the RQDX3 ever was (though you might want to keep it installed to drive
a floppy).

Micropolis 1558 ESDI + RQDX3 ?
No. The cabling looks similar (one wide and one narrow cable)
but they do not work with each other.
If you can find a Webster/Sigma Q-bus ESDI controller, though,
you are in fat city. When I moved off a RQDX3 and onto the ESDI
controller circa 1990, I was so happy.
Emulex ESDI controllers aren't too shabby either. (Although I
far prefer the Websters.)
