A couple of other things have come to mind.
DEC DataSystem usually indicated that it supported *DIBOL running under
OS/8, RT11 or VMS
They were intended to be a business package system ready run and often
included training, installation
and maintenance.
There's a possible confusion here 'DEC System' refered to a DEC10 or
DEC20 and DEC DataSystem to one of these package jobs.
*Program Structure like COBOL. Syntax like Fortran/BASIC. BCD Arithmetic

That is an 11/70, but with the "remote diagnostics console". You will
find a M8255 KY11-RE in there to connect up a modem to give remote
console access. Probably hooked up to a modem that was owned by DEC
maintenance org and leased as part of the maintenance agreement. I'm
sure that sometimes they asked for the modem and console back if the
maintenance contract was terminated but as a practical matter I find
that they hardly ever reclaimed the equipment.

Hi,
Yes it was indeed a DIBOL based machine. I think it was used as a business
administration system of some sort, possibly for the printing industry.
When I viewed the machine, it was deeply buried under boxes of paperwork and
so I've not had a chance to fully inspect the CPU cabinet. The reason for
having to crane it out is that the machine is on the first floor of the
office building it is stored in and I decided the few hundred pounds it
would cost to hire a crane were considerably less than the back surgery I
would require if I attempted to get it down the constricted stair cases I
was faced with. Plus I could get it out in one piece rather than having to
dismantle. Luckily the build has a nice large (reinforced) flat roof, so
should be a case of wheeling it out and craning it down.
I'm still suspecting the machine to be an 11/34 as I couldn't see any sign
of a full switched console so suspect there is a keypad hidden away
somewhere. Regardless it will be a nice machine to add to my growing haul of
PDPs and VAXes (upto 40 now)
Out of interest, how many UK PDP-11 owners are there on this list? Might be
worth assembling a little SIG to allow us to swap parts etc
Thanks,
Toby

Hi,
Well my collection is starting to grow out of control! Here is what I have:
3 (poss 4) 11/34s
11/44
11/05
5 x 11/73s
3 x 11/23s
11/03
11/83
couple of 8a's
WP-78
various drives (RL01s,RL02s,RK05s,RX01/02s and lots of RD and SDI
winchesters)
spares to build up another 10-20 qbus machines (although prob not enough
boxes)
more microvaxes than I care to remember (mixture of pizza boxes and QBUS
machines)
On the non DEC front I have an Interdata machine (can't remember the model)
and a small collection of Apples/BBC micros
My long term aim is to try to get an example of each of the main -11s built.
Probably an impossible ambition, but you have to have an aim. I'm hopefully
going to secure a couple of 11/70s and an 11/60 shortly to join the
collection. I suspect obtaining the older 11/20s,11/35/40s,11/45/50/55 will
be the biggest difficulty in completing the line as all of them by now
should have secure homes.
Cheers,
Toby

Me too. Regrettably I've not had the time to put any of them together,
so I don't have a working one, just enough bits to make three 11/73s if
I had the time to either assemble the innards of a BA23 (thanks Henk) or
sort out an old 18 bit serpentine enclosure...
Talking of which, does anyone have a spare BA23 (or similar) that they'd
like to sell or swap?
There was some traffic earlier about having a meet in London in early
?September - did it happen?

I've got one, but it doesn't work properly. From what I remember, it claims to
be a PDP11/83. At the moment, neither the hard drive nor the floppy drives
work, which limits its usefulness a bit.

Me too. I've got a Micro 11/73, currently hors de combat awaiting a
power supply repair (still cna't trace a schematic, but never mind, I'll
manage).
