If I had it, I'd use it. I only have Qbus MFM (RQDX1, RQDX3), SDI (KDA-50),
and Systems Industry proprietary (SI9900) controllers. I don't even have
an ESDI or SMD controller (but I do have a pile of ESDI and SMD drives).
It's been a big drawback when attempting to play with a real OS on real
hardware (as opposed to emulation). I have a couple RD54 drives a few
RD53 drives, a couple RA81s, a couple of RA70s and lots of <1Gb SCSI
disks (and <150Mb MFM ;-)
I always wanted to run 2.9BSD on something real (had the tapes since 1987).
Never had the right combination of CPU, controller and disk to make it
work (except for playing with a dual RL02 setup - it loaded, but there was
no room to do anything). I did dump the tapes to image files and emulate
the whole shebang on my first SPARC1 in 1994 - ISTR it ran about 30% of
real speed.
Anyway... if I could find a Qbus SCSI controller for <$200, I'd be
interested. If I could find one for <$50, I'd buy it on the spot.
