OK, looks like you indeed have an R/W RL02 image loaded. If this
is a VAX simulator, you will also need the KA655's ROM image (its
usually called ka655.bin or similar), so the VAX can load it and
then execute it.

After doing all the device attachments in SimH, you "boot" the
VAX by typing:

simh> boot cpu

which basically loads the ROM file, and executes it, reasulting
in the usual display of selftest messages, and ending you into
the wellknown >>> prompt.

A "show device" should indeed tell you it sees a DLA0 device,
which you can boot the usual way (boot dla0:) ...
