This is a twin/duplex cable of varying length with 100/140 um "multimode"
cores and SMA-906 connectors. SMA-906 connectors have the stepped
center-pin, compared to the SMA-905 which is a simpler straight pin. It's
used, for example, by the LAN Bridge 100.

Probably it has an orange sheath so it would be somewhat distinctive in your
tangled pile of cables :-}.
Thank you for looking,

I attended Queen Mary College from 86-89. They had just received several
dozen MG1s. I believe the WCW founders came from QMC.
By the final year a good 1/4 we're non-functional as the keyboards has
failed and by then WCW has gone bankrupt a second time (for good). I
remember one the programmers trying to encourage the more enterprising 3rd
year students to take on building a IBM keyboard adapter as their final
year project :-)
I'd love one for nostalgias sake but I live in the US now though shipping
to my mum's may be possible though no clue if they can handle 120v.
Lots of good memories. Eliot Miranda worked at QMC and had ported his
BrouHaHa smalltalk to the MG1. I remember using Occam (emulator), Lisp,
ML, Modula2 and C plus of course Smalltalk 80 all on the MG1.

Hi everyone!
I'm curious; other than Wikipedia what do we know about Whitechapel
workstations? Do any of us have some working in our collections, with
software, disk dumps, etc?
Cheers!
Hi,
n00b alert
Does anyone have a 101 level boot strap guide for someone wanting to get
into creating better-than-dd disk images?
I'm finding myself back in a position where I want to image / preserve
multiple 5¼ & 3½ inch disks. I think all of them are PC compatible
disks. Probably standard FAT-12 and a handful of super capacity disk
formats from the likes of IBM / Microsoft where they tried to squeeze
1.6 (?) MB on a 3½ inch disk.
I have an internal 5¼ inch floppy drive that is in unknown condition
(I've never used / tested it since I got it).
I also have (at least one) 5¼ disk that I acquired as a scratch monkey
disk to test on before working on disks that I care more about.
I was thinking about acquiring a Kryoflux in the next few months and
starting to collect better quality images of disks. I recently saw
someone on Twitter suggest that Kryoflux wasn't the best route to go and
suggested a SuperCard Pro instead.
I had been using the dd command under Linux against a USB connected 3½
inch floppy drive for most things. But I've come to learn that's not as
good as some people would like to see preserved.
So, does anyone have a 101 level boot strap guide for someone wanting to
get into creating better-than-dd disk images?

Yes hello, this is me. In fact, if you would like to see the Whitechapel
MG-1 in my possession in operation, come up tomorrow (Sunday) to the Centre
for Computing History in Cambridge, where the system is on public display
alongside an AT with a busy bunch of Transputers in it. It's all part of
the Retro Computing Festival that's underway this weekend:
http://www.computinghistory.org.uk/det/69485/Retro-Computer-Festival-2022-S…
If you can't make it to Cambridge, then when the machine is running (which
it isn't at the moment --- wait for between 10 AM and 5 PM GMT Sunday), you
can visit the machine over HTTP at http://mg-1.uk . (Note no https.)
Working MG-1s and related machines (like the colour CG-1) are rare owing to
leaky batteries (what else).
I'm very grateful to Tony for his generous sharing of MG-1 materials --- it
helps make it possible to show off the MG-1 in this way! I've got
everything on Google Drive, with links available on the website just
mentioned. Since it's liable to be down when you're reading this, here's an
archive.org link:
https://web.archive.org/web/20210625124716/http://mg-1.uk/
Note also this page with links to 42nix 2.6 OS media, also owing to Tony:
https://web.archive.org/web/20210625124758/http://mg-1.uk/42nix/42nix.html
You will probably have to edit archive.org's links out to Google Drive in
order for them to work, but I think it should be pretty easy to do this.
I have been meaning to make disk images of my best-effort reconstruction of
a clean 42nix 2.5 installation (a predecessor to the version linked above),
which I derived from a disk image taken from one of Jim Austin's MG-1s.
There is not a vast difference for the user at the console between 2.5 and
2.6, although they did fix a bug in the TCP/IP implementation that allows a
forking HTTP server running on 2.5 to cause a kernel panic. I suspect
revisions to TCP/IP were required to get NFS working, which, I remember
concluding, had been a new feature for 2.6.
I've never been able to get my hands on GENIX.
All sorts of spare boards, including things like never-populated bare

It took me a lot longer than I like to admit to realise that HITECH was
derived from wHITECHapel...
Speaking of discoveries, I found out today that the Centre for Computing
History is in possession of a couple Hitech MIPS machines (sans cases).
Apparently they might have some media on QIC tapes as well. Tony, I'll try
to get you in touch with the person I was speaking with about this.
Meanwhile TNMOC at Bletchley are in possession of three MG-1s.

My apologies if this topic is a sore point for some of you. Their abrupt
closing wasn't that long ago.
Does anybody have any insight on what is going on there? The web site has
not been updated in about 2.5 years. The world seems to be moving on; it
would be nice to know if we're ever going to see the museum re-open, and in
what capacity.
I realize the people are gone and scattered and it's never going to be the
same experience if it re-opens. But there are plenty of us who still
believe in the need for such a place, and starting from scratch would be
difficult.

Same here. I have not changed my email service, so that is not the cause. The change began when the new list server went online.

Hi,
Is anyone else getting 4 to 10 digest emails a day, each with 4 to 8
messages?
(cctalk) (Instead of one a day)
I have received four digest emails since noon: 2:57PM (8 msgs), 3:47 PM (7
msgs), 5:44 PM (7 msgs), and 8:24 PM (6 msgs). (Yes, all embedded messages
are different.)
I tried emailing the list owner, but the only response I got was from a
moderator (Lawrence W, who specifically said he wasn't the owner), who
wasn't able to help me. (He did suggest checking my mode...see below.)
I tried going to the website to "login" and check my status...it said my
email address wasn't known (which, of course, was patently false...since
I'm receiving emails :)
So, I tried: subscribe with sieler(a)allegro.com, ensure I have 'digest' mode
on.
And.....still get multiple messages per day ... *not* what a digest is!
This started happening on the order of 3 to 6 months ago. I used to get a
single digest a day, with 20 to 50 messages in it.
The multiple messages (even though they're smaller) are really annoying.
As a possible clue...somewhere around March we (my business partner and I)
sold our domain, allegro.com, in the process of retiring. The new owner is
providing two years of email forwarding of sieler(a)allegro.com to
sieler(a)allegrosupport.com (the latter is a gmail corporate managed account,
as allegro.com had been prior to March). (Oh, I tried "logging" in via
both domains with no luck.)
If the forwarding is a factor, I could try to get allegro/allegrosupport
unsubscribed and use a third account :)
thanks!

As it turns out, I have a complete, working HP 3000 917/LX system, with
printers, a line printer with stand, 14-port terminal concentrator, four HP
700-series terminals (one new in box, one likely dead), SCSI disk storage
module with a couple of 2GB drives, DAT drive, and all of the necessary
cables. It all seems to work perfectly (with the exception of the one
worn-out terminal), and I booted it up a couple of months ago with no
problems. The passwords have been removed from the MANAGER.SYS account, so
the system is now wide open. There's also some software: ASK/ManMan,
FORTRAN, and of course TurboIMAGE and Query; also a copy of Reflection
(Windows emulator for HP terminals). There's also in excess of 100 pounds
of documentation, and some boxes of paper, including green-bar (remember
that?).
The thing is, despite aspirations from my youth, I really don't need a
complete timesharing computer system in my house, so I'm looking to sell the
whole thing as a package. It seems possible that someone on this list might
be interested, and I'm also open to suggestions about other places I could
list it. I took it to the west coast Vintage Computer Faire this year, and
there were several nibbles, but obviously I still have it. It's currently
located in the San Francisco Bay area, but I commute semi-regularly between
there and Portland OR, and could be fairly easily persuaded to deliver it
anywhere in either of those areas, or in between. (The system will fit in a
mini-van - barely - or comfortably in a full-sized pick-up truck with room
to spare.) I'd like to see $2000, but will cheerfully entertain offers
(cheerfully if they're reasonable, or met with hysterical laughter if not).
Feel free to contact me off-list if you'd like more details and/or pictures.
Thanks!

I have a box here of 14 DZ11 Unibus 8 line serial port interfaces. And I
have no clue why I have them.
Anyone need some? Otherwise I'll Ebay/recycle them.
