G'day Dave,
The "UNIX PC" is the 7300, which is nearly identical to the 3B1.
The
3B1 has a slightly larger top cover to accommodate a full-height hard
drive, while the 7300 will only hold a half-height drive.
They are otherwise identical, using 68010s.
Okay. I've seen one of the 68010 jobs and repaired the psu for a friend
in the early 90's with a discard he'd taken home from work. It's all
pretty vague as this was about 1993, 1994.
I'd sure like to know more about the "proprietary cpu" version
you're
talking about.
Same guy had some "other" VME (Might not've been.. was rack mount and
telco power) AT&T gear at work that I saw a couple of times. Moved a
couple of bin's off the system and tried to get it running on the m68k
system he had at home which didn't work. We were pretty in the dark
about these things and doco was scarce and assumed that "AT&T meant they
were compatible". The idea behind the home machine was a learning
exercise, fiddle system for home. Old guy that managed a lot of the
esoteric stuff at his work said when we questioned the incompatibility
said "of course not. It's older than the m68k workstation, and it's all
micro-coded off bit-sliced CPU's". Maybe it wasn't? Either way, the rack
stuff's binaries were not runnable on the SysV r3.5 m68k jobs.
I only really remember it because AT&T stuff was around '93/94 pretty
unique here in Australia. At the time I was pretty obsessed with
HP/Apollo and SGI kit.
Al.
Rob,
2 MicroVAX 3400's went to Sampsa. I still have one VAX 6310 to give away (diskless).
I just wonder is it any use to ship those PDP-11 parts, since it's going to be expensive.

I'm not exactly sure, I only saw one for a few minutes, and
that was
about twenty years ago. I believe about the size of a good sized
kitchen table. And about fridge sized. (Refrigerator to all of you.)
This really depends on what you mean by "PDP-11/24". The
processor chassis is quite small (in PDP-11 terms), either a
3U or 6U rack mount box. When built into a *system*, with
drives and what not...it will be larger of course. The
largest "factory" 11/24 system I've seen was two short racks,
not much to it.
The 11/24 is a very late-model PDP-11, based on the F-11
chip, same as the 11/23. Not fast, but low power consumption
and pretty reliable.
Dave this is the fault of a big brown fellow watching you.
They allllways do. :-(

The 11/24 is a PDP-11/23+ on the UNIBUS. It can accommodate the FPU
(chip or board) and the CIS chipset. The size of the unit varies. The
largest front panel is 1 DEC system unit (10.5 inches tall) that fits in
a 19 inch rack. I managed one of these (a long time ago) that ran
RSX-11M with LDP gear. It also ran RTEM-11 (RT-11 Emulator), when I
supported RT-11 at DEC Software Services. Several users could work on
RTEM-11 at the same time as the LDP hardware was being used. The system
never missed a beat! Oh... The entire system ran on two (2) RL02's!!!

The 3B1 and 7300 are nearly identical. The 7300's chassis only
accommodates a half-height hard drive, while the 3B1 has a taller top
cover (a "bulge" underneath the monitor mount) accommodates a
full-height drive.

Hello!
That very loud noise you hear is every single machine (who is turned
on) being not very polite. I can imagine that happening.

It'd be a pretty nifty addition to a collection, I'd love a really old school Unix machine.
I'd not call the 3B1 "old school", but they're lots of fun. I've had
a bunch of them over the years, including used one as my main desktop
machine for a while in the late 1980s. I also worked at a store that
sold and serviced them.
If memory serves, the UNIX dialect that they run is SysV release 2.
It's a fairly complete SysV implementation, with a nice, low-overhead
GUI called "UA", for User Agent. There is no networking, but there's a
(rare) Ethernet card for the machine, which was shipped with an IP stack
written by Wollongong. The IP stack ran in short spurts between
crashes, but you could use it to get stuff on or off the machine.
I have two 3B1s now. I like them a lot.
They seem to be very interesting systems.
If you really want "old school UNIX", find a 3B2. Or REALLY old
school, v7 on a PDP-11.
Or v1 on a PDP-7. :p

Wasn't there some bitsliced cpu variants ?
Of the 7300/3B1? No, not that I'm aware of. They're call 68010-based.
I know there was the AT&T UNIX PC which was a 68010 + custom external
MMU, but there was also a proprietry cpu version I ran into the trap of
in a past life.

I'd sure like to know more about the "proprietary cpu" version you're
talking about.
He's thinking of the WE designed processors that were used in the
later units. They were not bit slice but were fabricated using the
normal methods. Not surprisingly enough the devices could not even be
sold separately.
They were ran an appropriately written release of UNIX as native. One
of the first applications for them and the later models was in running
the first and second generation Electronic Switching Services
otherwise known as exchanges.
I didn't think he was talking about those at all. Those are the WE32K
processors used in the 3B2/5/15/20/etc family. They predate the 3B1
(despite the unfortunate naming) by quite a while. The WE32K family is
no more "proprietary" than any other processor.
