Hello list,
Have been fooling around with my 11/04 and all is great, but problem is I have no 70s peripherals. I only have 80s stuff; i.e. MSCP/RA/DU disks and tapes.
So I'll need boot ROMs which supports RA and DU disks. Because my 11/04 used to be an embedded CNC drill controller, in the place of the regular CPU diagnostic is has a weird proprietary program which tries to initialize some long-gone/dead equipment which used to be connected to the PDP.
In summary, I'm willing to pay a fair/reasonable price for the following M9312 ROMs (unless some one has spares, then I wouldn't mind them free of course :-)):
1. Console Emulator and Diagnostic ROM (P/N 23-248F1)
For use on 11/04, 11/05, 11/34, 11/35, 11/40, 11/45, 11/50, 11/55 systems
2. UDA50 DU Boot ROM (P/N 23-767A9)
For booting from RAnn/RDnn MSCP disks
3. TK50/TU81 MU Boot ROM (P/N 23-E39A9)
For booting from TK/TU TMSCP tapes
4. RX02 DY Boot ROM (P/N 23-811A9)
For booting from a RX02 8" floppy
(don't have one now, but trying..)
5. RL01/02 RL Boot ROM (P/N 23-751A9)
For booting from RL01/RL02 disk cartridge systems
(also don't have one now, but trying...)
Thanks.

Does anyone on the list have a working copy of VTServer
that works properly on the Windows 2000 platform? Today
I was going to attempt to move an RL02 disk image from
my PC to a real RL02 on a PDP-11/34, but the VTServer
version that I have continuously echoes the last character
that was sent from the PDP-11 to the console (in RT11,
it repeatedly displays the '.', over and over.
Thanks,
Ashley
Hi
I doubt one can fetch data with most PC's from the parallel
port fast enough to keep from being overrun, even on a byte
wise basis. That is why I've suggest the DSP. May of these can
run fast enough to do it on a BIT wise basis and
require no external hardware, other than buffers.

Some time back on the vintage computer marketplace
(http://marketplace.vintage.org/), somebody listed a "dumpkopf 1"
computer, but only the most vague information was given about it. I
think there was some speculation here that it was maybe a hoax, and that
no information could be found about it on the internet.
I accidentally stumbled upon the machine at this web site; I suspect
that this guy was the lister in that marketplace ad:
http://community-2.webtv.net/ARCHAICAUDIO/WESTERNELECTRIC/page15.html
It looks to be very interesting, perhaps significant, but certainly
inoperable. The web page has a number of very interesting pictures of
the computer, and says that the tubes have a 1954 date stamp on them.
There are some large patch panels on the machine, so perhaps it wasn't a
general purpose programmable computer (in fact, the name implies the
machine isn't all that smart!)
Anyone ever used a Benson 1645-R plotter?
We dragged one out of store at the museum the other day. It does its
test plot fine, and we look to have got a terminal talking to it as far
as handshaking and sending characters via the SA interface.
It's not responding to HPGL commands at all though - in fact it's not
responding to anything sent down the serial line, other than the
handshaking being ok.
We're using the 'SA' interface which has one RS232 port and one unknown
9 pin port.
We also have an 'SW' interface module, which has two ports on it - one
male and one female. According to the (nearly useless) documentation we
have, one is for a terminal and one for a host computer - but it doesn't
explain the point of that (i.e. whether we should be trying to drive the
thing from the terminal port or the host port).
Nor does it explain what the difference between 'modem' and 'hardware'
connections are (surely the plotter knows nothing of what's actually
connected to its interfaces and doesn't care), what the difference is
between local and remote mode (this is different between manual and auto
mode), what the difference is between normal and emulate mode (emulate
what? Selection of Benson or one of various HP plotter types is a
seperate menu option, so I don't think it's to do with Benson/HPGL
protocol emulation)
Nor do the docs say what the difference is between the flow control
options on the SW interface (partly why we gave up and started using the
SA one) - there's a choice of CTS1, CTS2, then XON 1-4. How those map to
the real world we don't know.
Grumble grumble. Anyone know how to kick the thing into HPGL emulation
mode so we can actually talk to it?
cheers
Jules
Folks,
Got a call from a friend today asking me if I'd like her VCS plus games so
I'm now in possession of yet another machine but with 10 or so excellent
condition boxed games, some of which I've not heard of before.
However it's the machine itself that's interesting as it has a low serial
(~70,000) and the case itself looks like what I call the 'US' case - extra
thick edges and sculpting on the back where the joysticks etc plug in, not
the plain flat back of the models I'm familiar with.
I'm guessing it's one of the first UK (ie PAL signal) models since there's
no CH2-3 selector switch visible and it has a TV/Game switchbox, but can
anyone shed light on why the case was that thick in the first place?
Shielding for US emissions regulations perhaps?
Cheers!

I got the message below from someone seeking more information about the
HP 9826. I'm sure some of you know more about this than I do. He's
particularly looking for information about the developement of the 9826.

Hi Joe,
My name is Tom and my brother, Mark Allen, was one of the developers of the
HP 9826. He helped implement RMB for HP and said he invented the knob
that was used on that series.
My brother passed away a few years ago and I inherited his production
prototype of the 9826 which Mark won in a team raffle. I am preparing to
donate the 9826 to (a computer museum) and I am looking for more
information about it to include with the donation.
I found your site in Google (http://www.classiccmp.org/hp/hp9-200.htm) and
am surprised to find such detailed information about these old machines. I
found your email address at
http://www.geocities.com/SiliconValley/Horizon/9107/collectors.htm.
Do you have any pointers to more information about the product and the team
that developed it? From your descriptions it sounds like you may have
worked at HP and may even have known my brother, Mark.
Thank you for any information.
Warm Regards,
Tom
Hi,
This was on the last list of items I wanted to get rid of but no one
seemed to want it. Here's your last chance otherwise it gets scrapped
(I don't really want to but I need it out of my place).
Please don't ask for parts off of it. That doesn't get rid of it and
only makes it more difficult to get rid of. If you want parts, take the
whole thing, then I don't care what you do with it.
Thanks.
