Re: Sold on eBay: Convergent Technologies S/50 a.k.a. Unix PC, AT 3B1 Unix Workstation

[Alan Perry via cctalk]

As I mentioned elsewhere, I worked on software for them at Burroughs 
('86-'89). I picked up a bunch of B25 stuff in '03, but I could never 
find any software for them. In retrospect, I wish that I has stashed 
away B25 (and B1000 (I was one of the last people in the office 
supporting software on the B1000)) stuff, rather than return everything, 
when I left the company.

pre-internet era, I had no hope to repair and reinstall this machine, 
it would be different today: - /

The B20, B21, B22 looked like this -

box-shaped and got wider as "slices" were added. The B20s were 
x86-based and the 3B1 (and presumably the CT S/50) was 68k-based.

Agreed; unfortunately an all too common story in the tech business world (see 
e.g. CBM, MCM etc.). Surprised HP survived Fiorina.

Yes; I first saw that package used in Series L machines and the B80 was

I used to have a tiny portable manual card punch.
An acquaintance used it to punch /* in the first two columns of his

Yes, it would, but how would you get 100% compliance wiht no mistakes from 
PROGRAMMERS?


A 360 s'posedly COULD be told to ignore, or to respond to something else, 
but that wasn't usually available.
Accordinglyly, when we needed to use a 360 to duplicate a deck that had 
JCL cards, we would turn the source/data deck upside down.  (hope that it 
didn't have '/' in column 80?)

Kernighan. While I nervously asked bwk to sign my copy of C, Marc had no
trouble initiating a conversation wit him. Marc managed to persuade bwk
to sign his 11/70 front panel, which he had brought along with him in
his backpack. "The good old days - Brian Kernighan"

Our friendship developed rapidly, and we have spoken every day until his
passing about a variety of topics - the main one of course being
PDP-11s. Marc helped me source my first PDP, he also picked it up and
delivered it to me. We had many fun times together, trying to fix
things, and unfortunately in some cases making things worse, for which I
blame the beer.

Marc was incredibly intelligent. I looked up to him, despite being a
similar age. It's hard for me to explain how much he meant to me, and
how much I am going to miss him. I know many others are feeling the same
way.

I miss you buddy.

Passing of a valued member

[Toby Thain via cctalk]

To the list:

It is with deep personal sadness that I write that young list member
Marc Grenville-Cleave, of Dorset UK, has passed away. He was known
personally to several list members.

I did not have the pleasure of meeting him in person but as he was a
longtime friend I wanted to write a brief celebration of his life and
interests.

Most relevant to this list, Marc was an avid DEC collector and PDP-11
enthusiast and rescuer: http://marc.cleave.me.uk//pdp11/index.htm
He was also the proud owner of a VAX-11/750, among other computers:
http://marc.cleave.me.uk/collection.htm

He was self-taught in many skills, including electronics, and had
natural gifts as an engineer. Around the age of 14 he designed an 8-bit
TTL CPU, which he called "Titan". You can read more here:
http://marc.cleave.me.uk/cpu/ &
https://github.com/bootnecklad/Titan-Specifications
The machine was wire-wrapped and soldered with his trademark meticulous
care, as you can see from the photos on the first site linked.

Here is a picture of Marc with some of his favourite machines (Titan in
the background): http://i.imgur.com/CCinlCS.jpeg

Many people knew him on irc, as "bootnecklad" or "bnl", in the
#classiccmp Freenode channel and elsewhere. His sense of humour was
unique, sparkling and irreverent.

Aside from his electronics and retrocomputing interests, he restored his
beloved Range Rover Classic over a long period and finally got it
roadworthy in 2016. He was a perfectionist in this project as in
everything else.

Most recently Marc was a Electronic and Computer Engineering student at
the University of Nottingham.

He will be painfully missed by very many people.

6000 series central memory uses the same memory blocks, in groups of 5 to make 
up 60 bit words, 4kW per bank, 32 banks in a fully loaded 6600 (128 kW).

Almost certainly a 6000-series core memory "block" from a PP. They
measured 6.75 by 6.75 by 3.625 inches tall, so you might check to see if

Re: Weird thing ID (core stack?)

[Paul Koning via cctalk]

The marking on the connector certainly says CDC.  And the next to last picture 
shows a black faceplate that pretty much matches what you see in 6000 
computers.  Look in the Thornton book 
(http://www.bitsavers.org/pdf/cdc/cyber/books/DesignOfAComputer_CDC6600.pdf 
) 
which shows a photo on page 31.  Two connectors, 30 pins each in 2 rows of 15 
matches what those memories use.

You could confirm it further by looking at the number of core planes in the 
stack.  The 6000 memory modules use 12 planes for the 12 bit PPU words (5 
memory units combine to make the 60 bit CPU word).

Finally, if you're inclined to take off some covers so you can look at the 
memory plane, the fact that it has 5 wires per core (x, y, x inhibit, y 
inhibit, and sense) is distinctive.  Most other memories have only a single 
inhibit wire per core, not two.  The details of how this is used are in chapter 
4 of 60147400A_6600_Training_Manual_Jun65.pdf which you can find on Bitsavers.

This is a more serious question than one might think, but I know you (Warner) 
have been around long enough to have gone to Interop when it was about 
improving network interoperability.

So here's a real example: I have an HP 3000 Micro GX with MPE G.A3.09 
(V-delta-9) which is very 1990.  And it has a LANIC, and V-delta-9 is late 
enough for it to be able to do IP over Ethernet (vs. V-delta-4 and before which 
could only do IEEE over 802.3).  And it has an FTP client.

So you might think I'd be able to move files between it and a modern FreeBSD 
box, right?  I mean, it's all just Ethernet, right?

Where it falls apart is that there's a bug in HP's TCP/IP ("NS Transport") in 
V-delta-9 and before, such that it tears down the connection with a failure if 
a packet is received with IP type-of-service not zero.  And the FreeBSD FTP 
server sets a socket option that gets FreeBSD to send that sort of packet.

At a previous employer, I went round with HP a bit on behalf of a mutual 
customer and got HP to issue a patch for NS Transport that corrects this 
behavior on the MPE side.  Clearly, I don't have that patch on this system.

FreeBSD is FreeBSD, and I can build its FTP server from source and change it so 
it works in this situation; but I think this should give y'all some idea of the 
hilarity that can ensue when you exhume a 1980s TCP/IP and put it on your 
network.

Source for the Pascal Compiler.

T microfiche explaining how to use ISOLTS and interpreting the
diagnostics.

There is a lurking bug in GTSS (the GCOS simulator) that is apparently
expressing itself in a GCOS library routine; I need to see the source for
that routine to make headway on diagnosis, but GCOS source was never
released, and is still tightly held, so that is probably never going to
happen.

This just a guess, but 'sort of'? It _is_ TCP/IPv4, so it's got compatible
headers, but I don't know if other parts have changed enough to make it not
work.

E.g. it probably only supports class A addresses, for instance, which is going
to influence the code for picking the first-hop router.

Also, the only driver is, IIRC, for an ARPANET interface.

Ah. I assumed that what had happened was that the set of source files at MIT
was just what was in the 'last release', and the NCP code had been discarded
by then.

I wonder if it's on a backup tape that MIT retained, somewhere?


So now I'm curious - weren't many other pieces of important software similarly

Just a 470R current limiting resistor and a 24DC power supply. On the

was the AMES-11, but now I see it seems to have a PDP-11 frontend.

I have the NIC card with fixed IP address from a late 70's U of Delaware's
QBUS or VAX (I believe), so I am ready to participate.  Please if you get
the chance send me a VAX 750/780 and a few cards and I am in.

Yeah, that one was retrieved only recently, when Chuck managed to read an old
dump tape I had of the MIT-CSR PWB1 Unix PDP-11. We didn't run NCP on that
machine, but I had squirreled away that code (and the BBN code) on it (in
case we ever had any use for it).

Really? It wasn't in the code dump at MIT?

> - Unix?

For V6 NCP, we have several versions:

  http://minnie.tuhs.org/cgi-bin/utree.pl?file=SRI-NOSC
  http://minnie.tuhs.org/cgi-bin/utree.pl?file=BBN-V6

(The latter includes NCP as well as TCP/IP.)

> - VMS?

I'm not sure a VMS machine was ever on the NCP ARPANet? Hmm, looking at a
'Hosts' table from 3-Mar-82 (NCP was only turned off in January of '83), I
see two machines with "xxx-VMS"names, and directly connected to IMPs, _but_
no OS is given. So maybe they were front-ended somehow?

There's a July '77 one at the end of this:

  http://www.walden-family.com/dave/archive/bbn-tip-man.txt

and a January '79 copy of the MIT-SAIL one at the end here:

  https://tools.ietf.org/rfc/rfc752.txt

Starting around '82, they are more common: stick a phrase from the header of
the above into the "this exact word or phrase" box in Google's Advanced
Search, and you get things like this:

It's interesting, I had exactly the same machine a long time ago, but 
with a different label. It was a Burroughs B20 distributed by Unisys

Most any real lock smith can make a key for you if you give him the lock. The

 Nice pictures of a 2108A !
 But no pictures of the key, (which has been worked out)

I asked around for v6 Unix with "NCP" code when the IMP code was
resurected, but never found it
