This means that the disk you are running from (DU0:) does not
have enough free space for RSX to allocate a checkpoint file.

Start over and tell SIMH to make DU0: (rq0) larger.   I would
suggest at least 32 MB if you plan to do anything useful with
the system.   Don't go above 500 MB, however, as the ODS-1 disk
structures can't handle anything that large.
