To mount additional disks, just attach them (in simh) and mount them (in
the OS).  Sort of like this (from memory, hopefully right):

$ pdp11
simh> set cpu 11/23+
simh> set rl0 rl02
simh> attach rl0 unix_v6.rl02
simh> deposit system sr 173030
simh> boot rl0
# ^E
simh> set rl1 rl02
simh> attach rl1 user01.rl02
simh> continue
# mount /dev/rl1 /mnt

Most people who graduate with CS degrees don't understand the significance
of Lisp.  Lisp is the most important idea in computer science.  --Alan Kay
