Mmm... Are you saying that I should install openbsd on the sun3 and
then the old SunOS disks would be readable? Or to use the sun3 port
code to figure out why the i386 code doesn't work and modify it
so that it reads the 68k FS on the i386 platform?

The former would mean getting a scsi CDrom drive and seeing if it would
boot in a machine that has a broken tape at the moment, and that was
designed to boot from tape. Would that work?

The latter means driver and utilities hacking on the i386 version...
There has to be an easier way.

That was helpful. Thanks. Prompted by this I dug out all the parts,
cleaned and reassembled a minimum set (1 SCSI controller, with the
tape on it and an old 500MB scsi drive (id 0) instead of the emulex
controller and the two ESDI drives, of which the boot one is dead (and
removed, I can't find it now). I was hoping that maybe the tape would
work and I could install on the new SCSI disk, and if the tape drive
still didn't work, I'd try a net boot. As it went, I got some memory
errors and the boot process halted. Further attemps didn't show
anything on the screen and a the 3rd red led in the back of the cpu
board flashes, so something is wrong. I'll have to disassemble more
and clean, but it would be a lot easier if I can mount or extract the
data from the disks individually on the openbsd machine that works.

Thanks for replying.

Augustine
