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!

Jay
