I've just picked up an HP120 (Z80 CP/M machine) on Ebay :-). The main
prolem (mentioned in the listing I might add, so I am not complaining) is
that it's missing the keyoard.
The keyboard connector is a 6-pin telephone type socket (RJ12?). A quick
look inside (well, what did you expect) suggests the keyboard interface
is contrlled by an 8041 microcnntroller and that it works at 12V levels
(not RS232, but 0V and +12V). There are +12V and ground pins on the
keyboard socket.
So I am looking for any/all of the following :
1) The correct HP keyoard (anyone know the model number?)
2) Details of any other keyboards that can be got to work.
3) Technical details of the keyboard interface.

Hi all
Anyone have any experience with or know about Fox Electronics
in San Jose (and/or Hayward) CA? I just saw their site
and I'd never heard of them before. Their web site is
pretty disorganized, lots of broken links, formatting
problems and missing images. They seem to be an IC
recycler/scapper. Anybody know if they have good stuff
of interest to retro-geeks?

Yup, they've been around for a LONG time, though never dealing in
retail when I knew them. I had heard that Bob Fox had a serious car
accident years ago, I don't know if his brother runs the place now.
As you say, they are scrappers /chip pullers. When I was going over
there, they had a place on Zanker, a couple of blocks down from where
Excess Solutions was.
There are lots of scrappers /chip pullers around still in the valley.
Most deal only wholesale (ever wonder where Halted gets there stuff?)
or just on eBay and really don't like to get walk-in customers.
Hi folks,
I tried to build and run adventure from Rick Murphy's website:
http://www.rickmurphy.net/adventure.html
I used the disk image from the page and booted my machine from it.
I was able to compile and link everything by means of COMPIL.BI and LOAD.BI.
When I want to start the game, I'm asked for the file locations. Then it
takes a few seconds (perhaps half a minute?) until the program tells me
about "Fatal error 8" - and that I should consult my "local wizard". But
who's the local wizard?
On SIMH it seems to work.
At the moment, I would like to know if it's my machine and it's FPP-12
or the software (perhaps not expecting the presence of a real FPP-12?)
which has the problem.
SIMH doesn't have a FPP, so I cannot test it :-(
I successfully ran maindec-12-dafpa-a-pb (FPP-12 data test) on my
system. Compiling small FORTRAN IV programs und running them with the
FPP attached seems to be working correctly as well.
So are there any known problems?
Might there be any problems?
Is the adventure game tested with a real FPP-12?
Does anyone know an emulator with FPP-12?
My system configuration (abbreviated):
* PDP-8/e
* 32K memory
* TD8E DECTape controller
* RK8E RK05 controller
* Teletype
* Some serial ports for Kermit and dumprest
If anyone knows anything, please let me know!
It would be very good to be sure if I have a hardware problem or not.
Don't want to search for a phantom problem.
Best wishes,
Philipp :-)
Hello,
I have a HP 1650A but no boot disk. I just search on web and get you mail about 1650A boot disk.
Do you still have the boot disk of 1650A version 1.xx image. I would appreciate for help here. Thank you.

It's also in the 1980 National Interface Databook; actually the DP8350
'series', but only the 8350, 8352 and 8353 are covered. As Al says,
they're pretty well the same chips electrically but with different display
parameters.

I have a PDP that was pulled from a rack (of which I don't have)...
rather than
running it 'bared skin'... I'd like to find a deskside pedestal to put
it in.
Anyone have one they care to give up/sell/trade/etc ?

Yes... a common 1980s small office configuration. Pretty big for a
single-user RT-11 system of the day (I was using a single RL01 for my
OS and development environment and a single RL02 for customer data in
1986). Not so bad for a small RSX-11 or small RSTS environment (we
were using a machine with only 4 RL02s for a RSTS-based accounting
system for a multi-million-dollar company in 1984).
> It came with two VT-100's and a LA36 DecWriter II.
Sounds like a small RSX-11 or small RSTS system, then, or perhaps it
was used with TSX-11. One doesn't usually see multiple terminals with
RT-11.
> My second PDP is an 11/73 in a desk-side case (is that the microPDP-11/73?)
The MicroPDP machines I've seen are in a BA23 (could be racked, could
be in a desk-side pedestal), with a 1" MicroPDP nameplate near the
power switch. It's spring-loaded, so you can pull it out and turn it
90 degrees for upright or racked orientation.

Oooh... nice. What disk? RF08? RK05F?

Good luck on that. I myself held onto a Quest Elf for a friend who
had to purge his place when he got married. I returned it to him many
years later when he was divorced. He was 16 when he built it and its
hand-made aluminum case and extra I/O to control the robot it sat at
the top of. He was quite happy to get it back in perfectly working
condition after so many years. I was happy for the use of it over
those same years.

So did we ever learn anything about VCF West 2009?
I had emailed Sellam a while back but haven't heard back.
In fact, when Sellam wanted someone to rescue that Microdata Reality
machine in Sandy, UT, I emailed him but didn't get a reply to that either.
Was the machine rescued? This was Sellam's original message:

Hey, all:
Does someone have a copy, PDF or otherwise, of DEC's "PDP-12 Adjustment

If so, please let me know. Thanks!
