Was there something in the way of you booting single-user?

I am thinking Suns of that era let you into a boot ROM (via BREAK on serial 
console, or L1+A on Sun keyboard and framebuffer console) from which you could 
enter a command like "boot -s” which would boot to a single-user shell.

And physical console access is a good place to start for the win.  It is less 
effective than it once was, but remains a good first choice.

Oh, the humanity...

I must admit, at the time, I liked the "3M" definition. It's also a
nod to the famed 3M corporation, which was one of the first I met to
successfully pretty much completely obscure what the three Ems
actually stood for, so diversified was its business that it was no
longer anything to do with its actual name.

So conflating 3 entirely unrelated Ems together, and the facetious
ETLA-style *fourth* Em, was, ISTM, a facetious reference to this.

It seemed like a laudable goal at the time.

Now, we all have them, and we've totally squandered that power. It is to weep.

Kyle, which framebuffer do you have?   Here's a shot of the color
framebuffer http://www.obsolyte.com/sunPICS/sun3/color360r.jpg  The
old monochrome framebuffers used ECL signals, IIRC, and that plus the
refresh rate might be problematic with modern displays.

I also have a 3/60 that is sitting out on my bench that would love to
learn the answer to this question.  Earlier this year I finally got a
Sun3 keyboard (yes... one can make a Sun4 to Sun3 passive adapter, but
I never got around to it) and somewhere I have an optical mouse with
the modular jack that goes with it (again, an adapter can be made).

Absent the answer, I was planning on starting out with a SCSI drive
(or an ESDI drive in a Sun3 shoebox) and a serial terminal, just to
get the machine running something.

All of my real Sun experience starts with the SPARC1 in the early 90s.
I didn't really get to play with the Sun3 line when it was current.

SunOS 2.4 Expliot (Re: Old Sparcstations

2018-12-06 Thread Jeffrey S. Worley via cctalk
The Sparcstation 4/330 I reworked the NVRAM chip on

I got it as-is from Computer Parts Barn in Asheville, NC.  It was just
round the corner from my home in Oakley..

The machine wouldn't start due to NVRAM, which I fixed.  It then
actually booted from the original drives, had an OS and data on it.  My
curiosity was piqued.  This is what I did:

I hung the drive on my PC running Linux (suse, iirc), and ran John the
Ripper on it.  I didn't get the root, but I got a user password.

I hung the drive back on the Sparcstation and logged in as that user. 
The machine was being used to model the exhaust from various
configurations of rocket nozzles.  The previous owner turned out to be
NASA at the Marshal Space Flight Center.

I wanted root.

I set out to abuse the OS, did quite a bit, had a hunch based on the
experience while sussing the NVRAM problem.  I set the date to 1970,
booted, and logged in as the valid user I'd got from good old John.

The machine bombed to a single user prompt with a kernel panic
'irrational date'.  Passwd worked to change the root pw to something I
knew.  I went back into the monitor cli, changed the date to the real
date, booted and logged in as root.

The version of Sunos was 2.4?

Just thought this might be helpful to someone.

I don't know that anyone did that back in the day - the pack cleaners
I'm aware of had arms that wiped the top and bottom surfaces of the

that RK05 packs _were_ opened and the platter/hub assembly removed,

The answer is Yes, if you really understand what your asking.

I've not used the P112 but I have used the combo part in it for FDC
interface and it does/can work with 8", 5.25", 3.5"
drive so long as you get the wiring right as they all differ especially
the 8".   It does do CP/M 8" SSSD format
which was the primary interest (RX01 was secondary and does that too).

The second half of that is the driver for the device as it can do it but
it does have to be programmed.

The combo chip is basically a 765/8272 with 9229 for clock and FDC
interface inside and is not unlike the
37C65/37C765 and remote relations.  Basically it can do any fairly
standard soft sector thing  assuming
its not one of the odd 1771/1773 formats or based on some unique
controller (intel 2D M2FM and RX02). 
The chip used was from the PC world and most people that had issues with
PCs and 8" disks were
trying to work with existing PC FDC drivers limitations.

During my days at DEC in the later 80s the definition of workstation was 1MIPS 
processing power,
1M pixels, Desktop or desk side (fairly compact).  Graphics and processing 
power were high
and lots of ram and sufficient local disk as well.  Most of the machines were 
RISC based,
Sun (sparc), MIPS, or ARM powered.

Reminiscent of NeXT's "3M computer":

1 megapixel, 1 megabyte, 1 MIPS.

ISTM that the Sun-1 fails the megapixel requirement, but on further

, only narrowly.

Ah! Excellent point. I have to admit, I was totally unfamiliar with
the very early Sun products. I was happy with my little ZX Spectrum
back then, and being about 14, wasn't paying much attention to the
world of academic Unix usage. :-)

Looking up the SUN-1, I see that it lacked a graphics adapter, and was
a text-only machine. I didn't know that. That alone means that it's
not really what I think of when I think of a Sun workstation: no
windowing system means that for me it's not really a workstation.

But as a single-user Unix machine, yes, it unquestionably qualifies,
and I need to redefine my terms and my thinking a little...

I don't think anyone is questioning that it's a workstation, and that it was
made by Sun.

I think the problem is over 'first' and that a Sun-2 is not going to be the
'first' model.

Not my claim; the author of the video's. Take it up with him, if
you're on the Rescue List.

But I am mildly curious what your definition of a Sun workstation is,
if it excludes a 680x0 machine with Unix and a big monochome bitmap
display...

Here are some pictures that hopefully clarify my question:

How do I separate the platter from the top of the cartridge/cover?

Before doing this, remove the disk from the pack, otherwise you cannot get it

Wait, by 'open' do you mean 'release the bottom dust cover',
or 'disassemble and remove all plastic till the platters are fully exposed'?


Of course I mean 'disassemble and remove all plastic till the platters are 
fully exposed'. I know how to remove the bottom dust cover

 ;-))


By 'cleaning' do you mean blowing dust out with clean compressed air,
or some kind of all-surfaces wash & wipe?


The latter. I have a couple of disks that need some tougher cleaning than 
just gently wiping the surface.
