When it happened to my PCjr web site I contacted eBay, referred them to
the original page, and asked them to kill the auction. eBay had a
specific email address for this type of complaint and they cancelled the
auction within a handful of hours.
Nobody can possibly think that when they go to a personal website and
lift the cover picture and text directly that they are just borrowing
something that is public domain. It does take a lot of time to put that
kind of information together, and I don't want it used for commerical
uses. You can rewrite or link to the content, but I learned it was
wrong to blatantly lift paragraphs back in 3rd grade. ;-0
Another seller asked me first before using the pictures and content. I
declined them, but did encourage them to link to the content so that the
next buyer would have a better idea of what they were buying and how to
get the most out of it.

Unfortunately so am I as I'm in Texas and the disk is in Scotland - that's
the main reason I'm looking for a UK site to help, as otherwise I'ld grab
it and hop on a plane to the Netherlands and take Fred up on his offer -
it would seem fitting to return the pack to .NL after all these years :-)

Yes it is. Our project (Edinburgh Computer History Project) has actually
recovered four or five otherwise lost OS's already and every one has been
a delight. We do have a few remaining which we're afraid really are
gone forever, but there's at least 2, maybe 3, for which we have paper
listings that we hope to get our hands on this year.
Meanwhile I'm holding off on saying yes to Fred in the hope that
someone within the UK has a working PDP11 that'll read the RK05.

By the way, while on the subject of PDP11's, is there anyone with
experience of simh who would like to try to boot a system off some
floppy images I have? I tried and failed. They're the 501Kb files
in this directory: http://history.dcs.ed.ac.uk/archive/os/deimos/disk-images/
O/S documentation and source is here:

thanks to all who have responded; I'm replying off list to keep
the noise down.

NT being NT4 or win2000 is really fussy as it controls devices with
and iron fist. I've forced it but it wasn't fun. Your problem with
extracting is a local problem unrelated to the emulator. Also forget
XP.
It runs fine under win9x but make sure the systems is really fast
as there will be competeing things going on taking CPU time. The
effects of that range from apparent slow access to a lot of IO as
retrys due to overruns on the serial lines. Fortunately winders
in the win9x range is not a port hog. I havent tried 98ME with
this but for a lot of things it's really bad.
The BEST as many have said is DOS version 6.22 being a good choice.
I keep a 486/66 system running dos 6.22 and Win3.11 so that networking
is easy to do but when I need something more or less realtime its
available.

As Tony has already said, yes there's a power-switching bus, using
3-core cables terminated in 3-pin AMP Mate-N-Lock connectors. The
control part is in the 861 (or equivalent) power controller and
consists of a small circuit board that drives a contactor (like a
3-pole power relay). Those controllers are 19" wide rack-mount units,
usually 2U or 3U high.
The "AUX" switch on the front of your 11/23+ can be used for this, but
there are some jumpers on the panel that ought to be changed - or at
least checked - if you do, because that AUX switch is also used to
switch the LTC on and off.
You should be able to find the printset for the front panel and see
what the cables and jumpers do.

Don't think 2.10 will run on non split-I/D machines either.

Almost.
Non I/D: 11/03, 11/05, 11/10, 11/15, 11/20, 11/21, 11/23, 11/24, 11/34,
11/35, 11/40, 11/60.
Split I/D: 11/44, 11/45, 11/50, 11/53, 11/55, 11/70, 11/73, 11/74, 11/83,
11/84, 11/93, 11/94.
Did I forget any? :-)

I've just found two more copies for the 2648A so if Al doesn't have it
already, I'll send him one.
--
I have a bunch of hp terminal manuals scanned. will bump the 2648 up
in the queue.
To pre-answer one question: no, I didn't get any operator keys for the boxes.
Are they difficult / expensive to find? If so, I'll go back on thursday and
dig thru the storage bins I found the machines in and look for a key...

>The "ORIGINAL" had an 8088 and two full height (Tandon TM100?) drives.
That would describe mine. I thought it was an 8086, but 8088 wouldn't
surprise me (I know it is NOT a 286).
I should also have the manuals and original software for it somewhere. It
should be a reasonably complete original machine provided I can dig up
all the parts (I just saw it this morning in storage, and it has the
keyboard/cover, which I thought I had lost on that one... so the physical
machine is complete)

A good day at the auction!.
I picked up a 11/73 in a BA11-S chassis and a couple of IBM 5150's that
I mainly want for the MFM hard drives
I also picked up another M68K qbus cpu in a BA11-MA chassis. This one
also has the eprom for the MACSBUG firmware monitor.
Thanks to the IS pdf on AL Kossow's site I know, with the unix eproms,
these are capable of booting a M68K version of 4.3BSD. (providing of
course I could find a copy of the OS or even compile the source).
But what OS can these boards run with the MACSBUG firmware? I now have
two of these boards but I have yet to find out what OS they run? Anybody
know?? These machines were probably used for lab equipment as they also
have an Extrel sticker on the cpu and an unknown Extrel branded qbus
board with two 20 pin connectors, There is very little printed on the
Extrel Qbus board for identification, my guess is that they are some
sort of serial board, an i/o board or even a floppy disk controller, but
the lack of any identifiable controller chip make it hard..any guesses??
Cheers
Tom
