Aha. Now that makes sense! Thank you :)
What that means to me then is that in the /34 the 9302 should only be
plugged in to a the AB unibus out slot and NOT in a MUD slot, otherwise, you
get a funny smell I bet :)
So what about the 9312 in the /34 then. I assume it can only (no matter HOW
it's jumpered) be put in a MUD (AB) slot, never in an AB unibus slot (Unibus
in or Unibus Out). ??
Then, this of course brings me back to my dearly beloved (sarcasm) /45. In
that machine, the cpu doesn't terminate anything from what I understand,
hence the 930 at the front in slot 1AB. I assume in the /45 then, you CAN
put the (appropriately jumpered) 9312 in the last slot (unibus out), and
that you don't put another 930 in that slot and put the 9312 in a prior AB
slot. Is that all correct?
Thanks so much!
