???? If it doesnt ask you for the root password for maintenance, then it
may be too damaged to recover....

I think you mean Solaris 2.3.  And yes, that would install  SunOS 5.3.

If you want a Solaris 7 kit, contact me off list, I think I have a few
of them around, and I'd want less than any kit Sun would sell you :-)

To really know what the proc is, at the open boot prom do a
'module-info' command....

If the loaded OS isn't beyind recovery, you should be able to boot from
the Solaris 2.3 CD, fsck the filesystems on your hard drive, and mount
the root partition off the hard drive, remove the root password from the
/etc/shadow file, unmount the mounts, reboot, and log in as root with
no password.

Depends on your CPU....  being as you have one CPU, and I'm going to
guess something like an SM40, SM41, SM50, or SM51 I'd either go with
Solaris 7 or 2.6 (anything earlier just gets 'buggier', 'slower', or
the like... unless you go back to SunOS 4.x) or go with a BSD (
OpenBSD or NetBSD) which should be pretty quick on that box.
