I actually was having a stupid attack. After looking up the codes on
the red LEDs on the bootstrap board, I determined that the problem was
that the halt switch was on. After setting it to the run position,
it boots to the START? prompt. I can boot off an RT11 pack in both
the RL02 drives. Both RL02 drives seem to work fine. On the RX02 dual
drive unit, drive 0 works fine and can read/write/format diskettes.
Drive 1 (DY1) seems to have problems and makes a constant clicking
sound any time I try to read or format a diskette, although I thought
I was able to successfully attempt to read a non-RT11 diskette in
DY1 earlier.
