Hi folk,
I am still looking for a DQ696 to allow me to get ESDI drives going on
both my microVAX and 11/73 since the Webster RQD11 controller failed I
only have the one. I'd also like to get old of an RQDX3 since I built a
Gesswein emulator and have nothing to test it with :-)
Do you have ESDI drives that have been formatted with a Dilog DQ696,
and you need a DQ696 to use the drives with their existing format, or
would it be OK to low level format the drives and any QBus ESDI
controller would work, such as an Emulex QD21, or a RQD11 from various
vendors?
Where are you located, and what is a QBus ESDI controller worth to you?
Here's an Emulex QD21 for around $100 in the US:

Does that exceed your budget, or wrong location, or not compatible
with your needs?
I probably have more Dilog DQ696, Emulex QD21, and SDC-RQD11-EC
controllers than I do working ESDI drives. At one point I had several
working ESDI drives that have now gone bad over time while not being
used. It's been a while since I tried spinning up any of them to see
if any still work.
