 I just picked up a PDP 11/23 in excellent
condition from an accountant
that was going to dispose of it. It has two RL02 drives and 10 disk
packs. My background in DEC stuff is only VMS, so I checked around and
found some info on booting the machine, which I did successfully.. once.
I was able to get a directory listing and type a few files. The system
has RT-11 v4.00 with a runtime package in Dibol for general ledger, etc.
I halted the machine and tried to restart it again, only this time it
complains. 
Congrats on the acquisition...

 The display I'm getting is..

Sounds like either the boot board (if the CPU is an 11/23, it is
probably a BDV11, if an 11/23+, it has the BDV-style boot roms), or
the device interface.

Since it is supposed to have RLs, try typing 'DL0' at the 'Start?'
prompt.  If this doesn't work, then I would suspect the RLV
interface...
