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.

Here are my notes to run 8th Edition Research Unix on SIMH.

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

Fell free to use, improve and share.
