Might be helpful to print out a copy of that figure and tape it to the
back of the BA123. I can never remember what the rotary and toggle
switch positions mean.
Success!
Congratulations!
I'd left the rear panel console settings how
they were when I got the
machine, I mean 'T' for terminal, right? Wrong... arrow for terminal,
'T'
for "sit there alternating between F and 9, and driving Jules insane" ;)
'T' is 'Loop Test'... Just be sure to follow the grant chain - the BA23 and
BA123 have a
hybrid backplane where the first few slots are CD slots and the rest
are serpentine (3 CD slots for BA23, 5 CD slots for BA123).
First 4 slots of a BA123 are Q22/CD, not the first 5. Page 22 of the
PDF, page 1-11, Figure 1-9 Backplane Grant Continuity of the same
manual referenced above.
