There are some new scans up now for 32/75 on bitsavers.org/pdf/sel and some 
software
under bits/SEL

I'll be working on MPX documentation next

Re: Gould 32/77 (was: NWA auctions)

[Tony Aiuto]

Yes. The 8 & 9 machines were ECL, the rest were TTL.  IIRC, those were the
32/87, 9780, PN9600.

David mentioned disks on the PN (Unix) series. Those were formatted with
multiple of 512 byte sectors. The RTM/MPX machines used 768 byte sectors,
which was super optimal for the disks they happened to ship with their
earliest machines, but then a right PITA for everyone who used the machines
for decades beyond that. It was not just the strange size, but I think the
minimal disk allocation unit was something like 16K, and you only got 8 or
16 chances to add new segments to that. You better know how big your file
would grow before you started writing.

It's all slowly leaking back into my brain. The early machines, were number
32/xx and ran RTM, their Real Time Monitor. The xx was, IIRC, 27, 75, 77,
87. Very much process control oriented. A terminal *could* be hooked up to
an editor task that could edit code and submit jobs, but then it could not
detach and let you interact with another program. The company I worked for
hacked up a task swapping capability on top of it so we could actually get
work done.  That was 1976 or so.

Around 1982?, they added an MMU and introduced MPX, the Mapped Programming
Executive. That was much more usable, but still with the problematic disk
layout. I think the numbering changed then to x7nn, where X was the overall
technology and nn was a size within that. I know there was an 8750, 8780,
9780, 6780, 2750, and 7750. Those were the MPX machines. The UTX (Unix)
machines replaced the 7 with a 0, giving David his PN9080 and PN6050.

For unrelated reasons, I have to clean my basement today. Who knows what I
will dig up.

I used most of the SEL/Gould/Encore machines.  The 32/77 was an original SEL 
design, from before Gould bought them. It ran MPX-32, their real-time OS. TTL 
based. The 32/87 was ECL, in a much bigger cabinet. They made slight hardware 
changes to the 32/77 and 32/75 and released them as the PowerNode PN7000 and 
PN5000, which ran UTX-32, their Unix port. IIRC, we took a few 77's and changed 
one board in the chassis to turn them into PowerNodes.

The instruction set was more RISC-y than CISC-y. The floating point was base 16 
exponent rather than base 2. Because of the way they did normalization, there 
were a lot of bit patterns which were impossible results. I made a lot of use

Ah, yes, "The Magic Roundabout" - was three 6040s and one 9080. I still
possess the Gould nameplate from the 9000.
They were the last machines we had that we though of as mainframes (even
if many would call them minis - but I think the racks were wider than 19"
so they clearly weren't minis!)

There's some interest in the story of how this system came together:
we did have a Honeywell dual 66/60 which was supplemented by the 9000 as
a time-sharing system when we had had it 5 years. 
After two more years we calculated that we could buy and maintain the 
trio of 6000s for less than the maintenance cost for the three years 
that the Honeywell was due to remain and gain a noiceable increase in
computing power (and a noticeable decrease in power consumption) by 
doing so … and actually managed to convince the bean counters of this.

I also forget what those colour terminals were. The first Sun came along
when it turned out that it was cheaper to buy it and an Ada* compiler than
the Ada for the Honeywell.
* Computer Science /insisted/ they needed an Ada compiler.
They never used it - but the Sun was useful :-)

Um, I don't think the 6000s were ECL - think they were a reimplementation of

Random Gould side reference.

We had a PN9080 and PN6040 at City University as the main systems in the
late 90's (accessed via the usual mix of ADM3As, ADM5s, some Sun3s and a
whole bunch of Whitechapel MG-1s, ans some colour terminals of which I
cannot recall the name, but I remember them having a setting where they
would auto colour characters based on their clas - alpha one colour,
numbers another, and two or three other colours for the rest of ASCII)

I remember looking at the filesystem and thinking "Mmm, on disk formats
with 32 bit timestamps but with padding ready to be taken to 64 bit when
needed, nice future proofing".

When the CS department finally moved away from their own 6040 it was left
forgotten in a room over the summer - in the autumn the aircon was found to
have failed, overflowed and the machine was sitting there with water all
over the floor and in a steam bath. Still running fine. Quite robust that
ECL :)

That's great! Might actually end up being a useful system. It will be

The 32/77-series was a 32-bit machine implemented in ECL, based on
earlier SEL designs, but is definitely Gould in design/manufacture.

Some of the machines in the series had a very powerful (for the time)
floating point unit (known as the IPU) that operated in tandem with the
main CPU that vastly increased the number-crunching power available

The machines were mainly intended for real-time control applications (as

The machine ran a real-time executive called MPX-32.

No, the 11/45 was pretty good, but not great for image 
processing and other programs with a lot of data.  Once we 
got the VAX, I rewrote NASA's Mini-VICAR image processing

I ended up with the TI-980.  The 11/45's got out of range for me...

9 minutes left on the other Gould 32/77; hope someone here ends up with 
it...

That's what I said when I quit bidding at $180.

I had one of those moments where I went "You know, I'd like to spend more, 
but I have a building full of computers, I can't really fit any more, and 
at $200+ it starts getting harder to justify it to the wife."


Which is usually a sign it's getting harder to justify to myself and my 
conscience is telling me it's time to fold.


But I sure hope it went to a collector.

(It's not often I find computer stuff within 2.5 hours of my home, too.)

The 32/77-series was a 32-bit machine implemented in ECL, based on
earlier SEL designs, but is definitely Gould in design/manufacture. 

Some of the machines in the series had a very powerful (for the time)
floating point unit (known as the IPU) that operated in tandem with the
main CPU that vastly increased the number-crunching power available

The machines were mainly intended for real-time control applications (as
used in the flight sim applications in the auction)

The machine ran a real-time executive called MPX-32.

Years ago, I had some experience with these machines.  They were quite
powerful for their time, and were also workhorses that just ran and ran.
Very robust design.

These are neat machines, and I hope that they end up in the hands of
someone that can care for them rather than ending up scrap.
