Well today I was able to go and pick up the SOL-20 that I had arranged for.
It included a bunch of interesting stuff, including the original manuals
and Panasonic TV monitor and cassette recorder. Also part of the package
are the following:
- MCS6500 Microcomputer Family Hardware Manual, August 1975
- A Guided Tour of Computer Programming in BASIC, (c) 1973
- Processor Technology Extended Cassette BASIC, p/n 727019
It would appear that this particular system was purchased at either
'Recreational Computer Centers' in Sunnyvale, CA or 'The Byte Shop' in
Santa Clara, CA in late 1977.

hey,
The root pass I set (or thought I set) doesn't work.
I did the boot -s thing and got a "***NO ENTRY FOR root IN
PASSWORD FILE! ***" message. When I try to set the passwd I'm told that
root does not exist.
I'm a newbie on suns, pity me.
thanks,

Assuming noone has set the prom security password, you could boot the
system with a known hardware problem, in an attempt to force the OS to
drop you into root. On much older hardware, and prior to sun prom
security passwords, the classic method was to unplug the keyboard, power
on the system, and when it dropped into root, plug the keyboard back in.
The method would probably need to be adapted for more modern hardware.
Of course, the brute force answer is to reinstall the system from scratch.
Or, install onto a different HD, and also connect and mount the hard
drive you have, and then edit the password file, and swap the drive back.

Nicheten worken with post 2.3. (5.2.3). Hardware faults won't get you
a root session in single user mode unless you're capable of supplying
the root password (which is fun when the problem is a hosed passwd or
shadow file).

Jeez, if you've got the media to do that then all you have to do is boot off
CD, deal with the configuration dialog long enough to get to the point
where you can break out and get a shell, mount the root file system off
the existing drive and then hammer _both_ /etc/passwd and /etc/shadow
(this case sounds like /etc/passwd got modified but not the shadow file).
No need to install anything...
And yeah, I've done this more times than I care to count -- although
it ain't _nearly_ as bad as changing the boot controller on a Solaris
X86 system. That's a delightful journey to hell and back.

Are you sure it doesnt ask for the Prom password on hardware faults,

I just tried it; no matter what I do I get prompted for the root password.
This makes sense; init invokes /sbin/rcS during startup; if anything
unhappy happens _that_ invokes /sbin/sulogin (yeah, I did make sure
that a prom password was set).
Maybe I'm not being forceful enough with this poor SS20... ;-)
From what I can tell by poking at sulogin, you can
duplicate the old
SunOS behavior by setting the value of PASSREQ in
/etc/default/sulogin
to "NO" -- but that obviously requires that you get your hands around
the machine's throat.

I don't suppose you have a SunOS CD-ROM to boot from so that you can mount
the drive and muck with /etc/shadow ?

Its a lot easier than that:
ok boot cdrom -s
Gets you a single-user shell, no need to deal with the install at all.
