So now, like me, you are stuck with a bunch of ESDI drives and no
controller!
I do have one DQ696, on my MVII in a BA123 box, but the other controller
was a Sigma that developed in internal faulure and which I used for RT11
on my 11/73 BA23 box.
Now I have to share the one controller between the two boxes. RT11 one
day and NetBSD another!
Like you, I sold all sorts of stuff for a song, including a
millivolt-on-HVAC common mode DT2765 a/d card that was $3000 when new! I
also had 3 KA630s and accidentally sold two, so now I do not have a
spare for the microvax either!
If anybody out there has a DQ696 or an RQDX3 available, I'd like to hear
from you!
cheers,
Nigel
