First thanks to all for considerable assistance.
I can now talk to the RX 211 on the Unibus.
First it did need the NPR jumper removing.
Secondly I made the system into an 11/84
(Processor in slot 1 nothing in 2 MSV11-J in 3 )
Finally I'm so used to hex modules in Unibus and the RX 211 is a quad.
Of course it needs to go in CDEF.
Switch on finds PMI memory ok counts up to 9 as normal.
Asks for choice. Type in B DY0 and we get a nice error message with lots
Time to become a 94 again.
Bonus: The other 94 chassis can become a 84 I have enough parts.
