I can mount it:
# mount -r /dev/sd1b /mnt
# ls /mnt
.profile  dev       etc       mnt       netbsd    sbin      tmp       var
bin       dist      kern      mnt2      ofwboot   sysinst   usr

Well, this doesn't seem to work well:
ok boot disk1:b -DV
Boot device: /sbus/espdma@e,8400000/esp@e,8800000/sd@1,0:b  File and args: -DV
The file just loaded does not appear to be executable.
ok debug search-directory
Stepper keys: <space> Down Up Continue Forth Go Help ? See $tring Quit
search-directory ?

ok debug search-directory
Stepper keys: <space> Down Up Continue Forth Go Help ? See $tring Quit
search-directory ?

ok " /ofwboot" do-boot
do-boot ?
ok 

It's a:
Sun Ultra 1 SBus (UltraSPARC 143MHz), No Keyboard
OpenBoot 3.11, 128 MB memory installed, Serial #8793333.
