I'm just about to stick an OS on the newly-acquired NeXT Slab (thanks to local
Freecycle list for providing, and Witchy for picking it up!)
Questions:
CDROM - do I need a 2048 bytes/sector one or 512 bytes/sector? (I have both
available, but it just saves me guessing the type!)
SCSI bus - in order to hang a (terminated, obviously) CDROM off the external
SCSI connector, do I need to enable/disable termination on the system board
somewhere, and/or enable/disable termination on the internal drive? (I'm not
sure if the internal drive is one end of the SCSI bus, or just a short spur
off the bus)
Memory - Can these things take more than 32MB? Purely curious - I don't even
know if such a thing as an 8MB 30 pin SIMM exists (this Slab currently has 8 x
4MB modules in it)
(I did get manuals with this, but they're right at the bottom of everything
else that's in the car!)
cheers

You need one with 512 byte/sector capability. A good rule of thumb,
if it will boot a Sgi or Sun box, it will boot a NeXT. I use Toshiba's
on my NeXT equipment. The external SCSI chain will auto sense the
presence of the external device, so just terminate the external drive
and everything will be cool. I've always used SCSI ID 6 for my CD-ROM
- why I don't know but it's always worked for me. The default SCSI ID
of the internal drive is 1.
The internal drive is on the internal leg of the bus, so it's
termination is seperate from the external leg of the bus.
I've never tried to run more than 32mb in a non-Turbo chipset slab. I
recently got some 16mb SIMMS. Maybe I should experiment.

I think the slab needs external termination. It was many years ago
that I had access to one - but I seem to remember a terminator on the
external SCSI connector even with no external devices.
Memory - Can these things take more than 32MB? Purely

Pass.

512 it would seem... I guessed and stuck my old Apple-branded CDROM on there,
didn't change any of the SCSI termination, booted the floppy, and off it went.
It's now got NeXTSTEP 3.2 running on there, with the developer tools
installing as we speak....
I love it when hardware and software just works like that - such a rare thing!

Still not got to the bottom of that one, though. There are only 8 30-pin
sockets on the system board (websites lead me to believe that some slab models
had 72-pin sockets instead), but the memory info option in the boot firmware
curiously shows 32MB in two 16MB banks, and in addition reports half the banks
as empty - as though the *system* can physically address more memory, but that
the system board just doesn't have the physical sockets to put any more in...
Bloody nice machines, though.

I have a Turbo Color Slab which takes 72-pin SIMMs. If I had to guess,
I'd probably guess that only the '040 slabs have 72-pin sockets.
If memory serves, there are four sockets in my slab.

That was one of the beautiful things about NeXT's. Usually everything
just works.

Agreed. My first love is still the Cube, but the slabs are very nice.

That display's probably the most clear and crisp I've ever used on any system
(no doubt it benefits from being mono - but it even beats all the mono systems
I've ever used hands-down)

Hmm, well this machine is an '040 @ 25MHz, but with the 30 pin sockets. I'm
not sure if that's a Turbo or not? I always thought the Turbo was exclusively
an '040 @ 33MHz - but quite possibly it's *any* '040 slab regardless of
speed?

Most of the time, drives <2.1gb just work. I did have some issues
with some Compaq ROMed Seagates but most others were seamless. Above
2gb you need a disktab.

Only those with the later chip set are Turbo machnies, even if they
run at 25mhz. The 25mhz slabs with the Turbo chip set are not real
common and were kind of a transitional thing.

Are they that rare in the UK? I still find them for free around here
(Dallas). Now Turbo Cubes and Dimension boards are another story. I
sold my spare Dimension board this spring within the first hour of
listing it in a users forum. I still have a spare 25mhz '040 Cube to
sell later this fall.

Right,
Next question ;)
I've stuck NeXTStep 3.2 on the machine, but it seems to have configured the
box to boot straight into a default user called 'me' rather than offering me a
login dialog (NeXT's equivalent to XDM).
I'm *assuming* that there aren't any post-install steps that NeXT are
expecting me to do as the 'me' user, prior to using the box as a complete
system. (I don't have docs for 3.2)
Purely for the purposes of installing other software, I'd quite like to change
the system to prompt for a login name at startup though - anyone recall how to
do this?
That way I can log in as root and have the full desktop environment available,
rather than having to drop to a shell and issuing 'su', working out the
locations / names of the file browser etc. that I need, figuring out CDROM
mounting and all that other fun stuff.
I'll get to the manuals tomorrow, but I'm almost certain they won't cover OS
setup, and even if they did would be the wrong version anyway :-)
Initial (and only, so far) irritation: the mouse is too darn slow. Even on
maximum speed setting, it's still sluggish compared to what I'm used to, and
needs far too much desk movement to get it across the screen. Funnily enough I
found exactly the same thing with the BeBox - so it's possibly a trait of
early 90's GUIs...

IIRC, you simply tell it you want to install additional software and it
prompts you for the root password. Of course it's been 5+ years since I
gave my NeXT slab away so I might be remembering wrong.

As I recall, open a terminal window and set the password for the "me"
user. Then log out. When you log back in it will ask for the user
name and password. You can then log in as root and set the root
password. most of the NeXT unix shell commands are pure 3.x BSD. Or
was it 2.x, I can't remember.

Hm, no real answer from me; my slab came with a root user already built
in, and for the life of me I can't remember how I got root access when I
did a total reinstall onto a new disk. I'm fairly sure James Rice was a
help here.
I'll get to the manuals tomorrow, but I'm
almost certain they won't cover
OS
setup, and even if they did would be the wrong version anyway :-)
If I can do it blind then you can too. I even patched mine with the y2k
install and did other stuff without help, pity I'm 250 miles away from
mine right now.

Yep, that's an irritation for me too.
