Hi,
Its near Reigate in Surrey. If we can get video that would be great, could
go on my
site.
Is the 11/94s CPU UNIBUS or does it have a QBUS backplane for CPU and a
qbus/unibus convertor? If its QBUS would an 11/73 CPU be of any use, have a
lot of them in my spares stack.
Cheers,
Toby

Hi
Now that sounds interesting. Where is it?
The reason I ask is I have a retired friend who has more video equipment
than the BBC.
A nice video of it getting craned out would interesting.
A couple of points re craning.
If there are no eye bolt holes in top of the cabs you need to have a
strong base to put it on and then a stretcher bar four rope sling down
to the base. Any side pressure will collapse the cab and crush anything
inside. I'd tend towards pulling the drives (and anything else fragile)
out of the cab.
The fact that there's no lights and switches front panel is probably due
trying to stop the end user doing something nasty.
If I read the runes correctly on other posts then light and switch front
panels are around and are a straight swap.
I have no fewer than four 11/94's but the KD11J CPU boards were stolen
before I got to the machines.
An 11/84 CPU (KDJ11-B) + Memory would do but I cant find one at a good
price.

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

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

Can anyone help me identify my latest PDP-11
rescue. Not been able to
get a good look at it yet as it is in a room packed (and I mean
packed) with junk. Machine consists of a DEC Datasystems cab (about
35-40U with a blue bottom panel, pretty similar to light blue cabs
here:
I'm not familiar with the DEC Datasystems
versions of PDP-11s. Does
anyone have any background information on them?
Also, I'm pretty sure I've not lucked out
and found an 11/70 as no
toggle switch console, any ideas on what other models were fitted to
these cabs. I'm guessing 11/34.
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.
Tim.
