I can install 4.1BSD just fine, but I seem to be having trouble writing anything to a second RP06:

# mkfs /dev/hp1a 7942
isize = 5072
m/n = 3 500
# mkfs /dev/hp1g 145673
isize = 65488
m/n = 3 500
# mount /dev/hp1a /v8
# mkdir /v8/usr
# mount /dev/hp1g /v8/usr
# cd /v8
# mt rew
# mt fsf 2
# tar xvpb 20
hp0a: hard error sn10 mbsr=82000<PGE,DTCMP> er1=0 er2=0
hp1a: hard error sn16 er1=5<RMR,ILF> er2=0
mkdir: cannot make directory adm
...

Am I missing something, or did I run into a SIMH bug?  My /dev entries all look fine.

These notes are quite raw and unpolished, but should be
sufficient to get Unix running on SIMH.

Fell free to use, improve and share.
