Just had to look it up.

"The O-level (Ordinary Level) is a subject-based qualification conferred as
part of the General Certificate of Education (GCE). It was introduced as
part of British educational reform in the 1950s alongside the more in-depth
and academically rigorous A-level (Advanced Level). England, Wales and
Northern Ireland replaced O-levels with GCSE exams in 1988."

So I must have taken the GCE O Levels.

This is an emulator of a GEC 4000 series minicomputer,
in this case emulating a GEC 4160, which had one of the
more interesting front panels in the GEC 4000 series
(albeit, an optional extra at the time). The GUI front
panel does actually work as it should (as far as I remember,
anyway). The GEC 4000 series starts in 1972, although the
GEC 4160 is about 1981.

The emulator has booted and is running OS4000, the main
OS which ran on these systems. The system console is on
the right, and a multi-access terminal on the left, where
SMAN (system manager, a.k.a. equivalent of root) has just
logged in.

I still have a real GEC 4162, which mostly still works
(just the ethernet controller has died).

I have a 3.5" disk (100MB SCSI). I have taken off the lid
and made a perspex one. The drive dates from when an SS
(Self Seek) jumper was provided, which makes the head seek
around in all sorts of interesting patterns for displaying
on exhibition stands, without needing to connect up anything
other than power (and could sometimes be used for testing
the drive). Unfortunately, the self seek pattern on this
drive (butterfly seeks) was not as wide a selection as some
others I've seen, but it's still very interesting to people
who haven't seen a drive operating before.

That's _new_ technology.

Wish I'd thought of that before I junked that 5.25 inch one last year...

And I always did want the big platter from a full scale head crash on a
14 inch drive!

I have a 14" exchangable pack, like this one:
http://www.vintageproaudio.com/photo...-plattertn.jpg

About 12 of the 20 surfaces are head-crashed.
That was particularly expensive in the case of my disk
as it was a head alignment pack, which cost megabucks
(someone told me £30k at the time just for the head
alignment pack, never mind cleaning up and replacing
the drive heads). The alignment packs were called "CE"
packs, because of the pattern they generate on the
engineer's 'scope, which looks like alternating C and E
characters laying on their backs.

I also have some 8" and 14" platters which had too many
errors to be usable, but there were no visible marks on
them (well, not before they were handed around a class
of kids).

I give talks on computing, and these make for nice props
for some audiences/topics.

My only touching of one was a PDP11/44 at Reading University (Dept of

and watching it boot (for 20-25 minutes!) was kinda cool for a 20 year

It's an 11/23 (that's the one with the CPU as up to four LSI chips).
Boot ROM is there, because in fact it has a ROM monitor that does the
work of the front panel (so no real switches, just a Boot/Halt one and a
couple of others).

I have on occasion keyed in a bootstrap on an 11, but most of ours (we
had several) had boot ROMs. But I can do it to my heart's content on the
little PDP-8 replica (although it too has a ROM monitor that runs in a
separate address space).

My only touching of one was a PDP11/44 at Reading University (Dept of
Engineering) in 88/89 - they had the ROM, but typing the loader commands
and watching it boot (for 20-25 minutes!) was kinda cool for a 20 year
old

We'd lost most of ours by then, and the only one I used was the little
PDP-11 used to control our VAX 8800 (you even powered the 8800 off and
on with commands on the 11).

Next task...getting the PDP-11 (a real one) running...

Which one do you have? And does it come with the boot ROM or do you have
to key in the loader?

It's an 11/23 (that's the one with the CPU as up to four LSI chips).
Boot ROM is there, because in fact it has a ROM monitor that does the
work of the front panel (so no real switches, just a Boot/Halt one and a
couple of others).

I was at York Uni late 80's, (Reading was a temp job mid degree). The 8550
and 8600 were loaded by MicroVaxen IIRC. Wasn't the HSC disk controller a
*******ised PDP? I always had a bit of a laugh lookign at that lot (part
time summer job). The Vaxen were really big expensive machines with 5kW
power supplies. Connected to the HSC disk controller with lot sof coax all
into a "CI bus Star Connector", which apparantly wasn't that cheap. Upon
closer inspection, it was a 2 drawer filing cabinet sized box with no mains
power and the coax sockets were hard wired inside.

Those were the days. Real computers and proper operating systems...

The 8800 was a dual 8600, but tha used an LSI-11.

I never found out. Ours was an HSC-50, with one of those slow TU58 tape
drives.

Yes, I did the same examination on ours (8800 plus 2 x 8200). I managed
that cluster, and did a lot of systems work (and wrote VMS device
drivers).

I still have three VAXes....! One of them is set up to switch on and go,
and I can log in from anywhere on the house network. Second greediest
machine in terms of power (PDP-11 is first).

Yes indeed. He was the Systems Manager. Don't know where he is now. Very
smart bloke.

That's _new_ technology.

Wish I'd thought of that before I junked that 5.25 inch one last year...

And I always did want the big platter from a full scale head crash on a
14 inch drive!

Chap at work had a big disk with various ICs around the edge and a clock
motor and hands. The crash mark was through to the metal and had scratched
it.

Chelmsford somewhere. Think I have his email address. We worked on
compilers and loaders together many years ago...he at York, me at Kent.

At the time, and still, I teach operating system theory and stuff...

Not too bad. 27 wired network sockets, 9 machines on 24/7. But we use
them a lot (four are 'infrastructure'). The VAXes are desktop boxes, yet
faster than an 8600....it's even faster if you run VMS on the VAX
emulator on the PC!
