Subject: Can I use a M9302 with a PDP 11/35?
Hi,
Before I do it - I thought I should ask :) Can I use a
M9302 as a UNIBUS terminator in a PDP 11/35 or 11/40.
The manual mentions a M930 which I don't have, but I do
have the M9302 which looks a bit more involved (has
some ICs.
The M9302 was from a 11/34 which is a later generation.
Having said that, the 11/35 does work without the
terminator - although I cant see a terminator on
the system.
Thanks
Ian.
Hi Ian,
I checked my notes (the machines are a bit difficult to
reach, I am moving in 3 weeks). In my notes, I have the
M930 as terminator. The M9302 is for the 11/34, because
of the SACK circuitry. Just a few weeks ago Tony wrote
a good explanation on the termination subject.
I don't know if you can put the M9302 in the 11/35 ...
If you are in the UK (which I seem to remember, I can
send you an M930 for shipping costs. If you are in the
USA, I can do that too, but is more expensive, and
perhaps somebody in the USA has one M930 for you.
