I pulled my maintenance manual but it wasn't of much help. If you have
a diagnostic disk I can walk you through what to do to diagnose the
problem. I suspect that the "0B" may mean that the unit is searching
for an external disk unit (either a 5246 or 5247 because you have one of
the I/O boards installed) and isn't finding one. If this is the case,
you can simultaneously press the "Cmd" and "Error Reset" keys (or if
that doesn't work, just "Error Reset"), and hopefully the computer will
continue booting to the "READY INPUT" prompt. If this works, you can
avoid the problem in the future by removing the offending board. I had
a similar problem with the board for the 5247 hard drive, when I didn't
have my 5247 hooked up.

Good luck.
