I forgot to mention that I did find that my RD53 was configured as DS3 and
changed it to DS1 (numbering from 1-4, not 0-3), but that made no
difference. I tried swapping the jumper on the M9058 from the factory
setting of TP1-TP2 to TP2-TP3, but it made no difference. Is that the jumper
you mean?

I have a MicroVAX II in a BA123 enclosure and I
am experiencing some
problems getting it to see the RD53. Whenever I try to boot I just get
the error DEVOFFLINE and the Ready light on the front panel goes out
when this happens (you can't get it to switch on again if you press
the button a few times).
The RD53 is known to work as it will boot in a MicroVAX 2000. The
RQDX3 also works as I have tested it in a working MicroVAX II (BA23).
Is it possible that the drive select jumper on the RD53 is on the wrong DS I don't know about a MicroVAX 2000, but in the
BA23 it has to be on DS0
for
one bay and DS1 for the other, but so long as you only
have one drive, it
won't
actually matter. In a BA123 with an M9058, it would
usually be on DS1 (or
DS2
or DS3, it won't usually matter).
But it's worth trying it on DS0. On the M9058, the four incoming drive
select
signals (DS0...DS3) are routed separately to the four
34-pin connectors,
so
one select goes to J2 pin 26 and via a jumper to 28,
30, and 32; another
select
goes to J3 pins 26, 28, 30, and 32, and so on (and the
ones that go to J3
and J4
also go, via jumpers, to DS0 and DS1 on the floppy
connector, J11 pins 10
and
12, so don't use those if you have a floppy drive
connected).
There's a catch, though. On each of J1...J4, the DS signal goes directly
to
pin
26, but via a jumper to pins 28, 30, and 32. So if
the jumper is missing,
and
you have the RD53 configured to respond to anything
except DS0, it won't
go
online.
