You can get the VAX-11 diagnostics tape here:

ftp://ftp.trailing-edge.com/pub/vax_dists/vax11780diagnostics_vaxsim.tap.bz2

Copy the tape to your system disk (example with a TS11 drive):

$ BACKUP MS0:/SAV SYS$SYSDEVICE:[*...] /LOG

The diagnostics live in [SYS0.SYSMAINT]. If you boot from your system
disk with R5 flags set to '10' it will boot to the diagnostic
supervisor. You need to attach several devices before you can see the
filesystem e.g.:

DS> ATTACH KA785 SBI KA0
DS> ATTACH DW780 SBI DW0
DS> ATTACH UDA50 DW0 DUA
DS> ATTACH RA82 DUA DUA0
DS> DIR DUA0:[SYS0.SYSMAINT]

DS> RUN DUA0:[SYS0.SYSMAINT]EVDYB

The help is in [SYS0.SYSMAINT]EVDYB.HLP

I think you can also copy a subset of the diagnostics to a console
floppy and boot from that. You won't have to attach the disk controller
in that case.
