I found the console terminal and I can talk to ODT. I think I have the
RA81 hooked up correctly. RA passes all the diags. The machine doesn't
boot. If I give it a B command, it runs for a second and halts.
There are 4 connectors for the RA, in bottom of the rack.
A B C D
Which does the RA cable go into? Is there a different command to boot
from an RA?
