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.
