I found this stuff in a pile of scrap boards last week.
<http://www.classiccmp.org/hp/Interdata/> I'm not sure who made them since
I can't find a manufacturer's name on them but a number of the boards have
a tag on them that says "Passed Interdata Processor Test" so perhaps they
were made by Interdata. Does anyone know anything about Interdata or know
who made these? The names on the files are the name that's etched into the
boards and I'm sure that they're some kind of computer boards. The dates
on the ICs range from 1973 to early 1976.

If you can point me to a picture of the 4000vlc that would do. Most of the
3100 boards are fairly small but by time you add the 3.5" scsi disks and
power supply it grows but the box is still 40% air.

I thought the 4000 as also BA42 (18Wx16Dx4H) like most of the 3100s
(save for M20E). I consider the BA42 box easily hid.

Hi,
This is my first venture (or an attempt to venture) into the world of VMS.
I have a couple of questions:
1) Is there an emulator, etc to run OpenVMS on and where can I get it as
well as OpenVMS?
2) Does OpenVMS support the notion of shared libraries (DLL to you windoze
users)...
I want to re-port an old application, but want to use OpenVMS instead. I
don't have a machine that is capable of running VMS (nor do I have the space
for one), so an emulator will suffice....
Thanks,
Ram
I have been trying to run diagnostic tapes on my PDP-11/40. It seems
that I am missing the documentation for many of the CPU diagnostics.
Does anyone have a listing for the 11/40 instruction exerciser? My paper
tape is MAINDEC-11-DCQKC-A-PB.
I load the tape and start it at 200 and it runs for a while and then
begins printing out:
PASS #0000 PC=015354 PSW=000000
PASS #0000 PC=015356 PSW=000000
PASS #0000 PC=015360 PSW=000000
PASS #0000 PC=015352 PSW=000001
PASS #0000 PC=015354 PSW=000001
PASS #0000 PC=015356 PSW=000001
PASS #0000 PC=015360 PSW=000001
PASS #0000 PC=015352 PSW=000001
...
This seems to run indefinitely.
I have tried several different switch setting as described in the PDP-11
Diagnostic Handbook recently online at bitsavers, but it always ended up
with this result.
Anyone have information on this diagnostic?

In the coming days, I am planning on selling two brand-new CSA TEK Boards
(master and slave) on ebay. These are 2 of the 3 remaining TEK boards I
have. I am planning on keeping one for myself. This will include the
extremely RARE 2 Mbyte daughterboards (2 of them!) and two packs of the
expansion chips (for the serial/parallel programming) and one unopened box
of TEK software (occam, logical systems c, etc). Unfortunately, I only have
one set of the documentation, but most of it is now online (except for the
Compiler writer's guide, CSA User Guide, and the Occam workbook). And
Roger, I really cant take on another box, regardless of how decked out it
is. Wife is too angry with the stuff I already have. Plus, I only need
something to compile on as I have no QBUS boards, etc. This is similar to
me running MacOS (on Basilisk/PearPC)....
Cheers,
Ram

Charon-VAX offers a freeware version now for OpenVMS users as well as Fedora
Linux users. But, I am going to use SIMH. I'll just get a version of
OpenVMS for hobby usage. The problem I have is more so with my wife than
really space. I already have a lot of stuff in my house and adding yet
another system will just make matters worse. The emulation route is more
suited for me.

This sounds more like what I want to do. I am in the process of re-writing
the iserver transputer host communication application to be a bit more open.
Currently, all the drivers are linked into the application which makes
adding new driver support a pain. I want to dynamically load the library
>from the application itself. For example, the configuration file would be
like this:
|c0t5l0|T|localhost|/dev/c0t5l0|transputer.so||||
So, when the application configures itself for c0t510, it will dynamically
load the file transputer.so and use the device /dev/c0t510 as its resource
(this is NOT a real example). Is this possible?
The library will have the standard INMOS communication API present
(OpenLink, CloseLink, etc)
Thanks,

I recently won an HP82915 Modem on E-bay (my first, and so far, only
purchase there). I was suprised to get it for the opening bid, I though
I'd have at least one other HP collector to contend with. It is, you see,
the internal modem for the HP Integral.
Anyway, it's a single PCB that fits into one of the Integral's expansion
slots. Cotnains about 20 ICs, most of which I recognise. One odd thing is
that the serial chip used is an 8250, a somewhat odd choice for a
68000-based machine.
Does anyone here know anything about using it? The Integral manuals I
have mention it exists, say it installs like any other board, and that
you need a normal 'modular phone cable' to link it to the phone line.
Nothing I'd not worked out by myself.
Incidentally, I have no intention of linking it to a public phone line,
I just want to connect it to another modem. I suspect it'll work withont
any DC voltage on the line, if not, that's easy to fix.
Did anyone, though, have a cheap/homebrew device to link 2 modems
back-to-back, doing things properly with dial and ring tones, etc?
