I have requested a copy of all the patents and info regarding the PDP-8/S
and the GRI-909. I will post them too.
I asked him for a GRI-909 but....
Unfortunately he thought no one was interested in the 8/S or the GRI-909 so
he hauled them both to the dump 6 years ago.
:-( :-( :-( :-( , etc....
I am *really* unhappy about that......

Anyone want a HP computer with HP-UX?

I found this in the CPM news-group. Sounds like this guy knows a lot
about the early Chinese CPM computers.

For few months I'm owner of VAXStation 3100 M48. It has 24Mb of
RAM, three 120Mb HDDs, TK50 tape and RRD40 cdrom. I'm quite new
in this kind of equipment an have very little of experience.
It's booting ok, two HDDs and tape works, but one of HDDs war broken and
disconnected. And the cdrom drive don't work. When I try mount it
I got 'Media off-line' message (It runs VMS 5.2).
Is it problem with some jumper settings on drive or so ?
Is it possible to get some hardware related manuals (I've few VMS
manuals downloaded from the web).
Thank you for any help.

Hi all
I need help with an HP/UX box. I don't know much about the
thing except that it has two hard drives connected to the
first (0) HPIB cable and a tape drive connected to the
third cable (ID 3). Problem is that the existing software looks
for the tape drive at /dev/rct/c7d0s2, and can't find it.
The device entry c7d0s2 has a major number 7 and a minor
number 0x400702.
Am I correct in thinking that the minor number related to
the HPIB address in some way, because I expect the tape
drive to be 4.2.3.0.0.0.
Please bear with me, this is the first time in my life I've
seen an HP/UX box, so I'm pretty clueless.
What do I need to find out about the box to make the tape
drive work?
Thanks
Wouter
PS: Anybody have Apollo 3500 hardware info for me? And where
can I get a copy of Domain/OS, my one tape seems buggered?

Keep in mind that VMSTPCE, by default, does a rewind before doing
the image, so your SET MAG/SKIP commands probably don't mean anything
anyway. You need /NOREWIND to force it to not rewind.
VMSTPCE also has the "/ERROR" switch to make it ignore erros. I
suspect your tape drive thinks its too smart to read past an error though.

For 800 BPI, you can always move the start-of-tape marker past the
crinkled tape. This will work for *some*, but not all, 1600 BPI tape
drives too. (There's a ID burst at the start of a 1600 BPI tape that
some drives will insist on finding.) Same for 6250.
>Eric, I guess you'll have to wait untill I have set up again the 3420 tapes;

What's the project, out of curiosity? I've only got a dozen 9-track
drives here that might help :-)

There are lots of other documentation still to find, though.
If you have a cable which separates the 3 video colors and their returns
>from the DE-15 and also brings up the two sync signals you're on your way,
but you need to put an adapter in the cable in order to allow you to invert
sync polarity in case the video board requires it. If you have 5 BNC's,
that normally means you don't need the 500-ohm resistor to green video from
the comp sync pin on your video board's application connector. That just
imposes sync on green, which won't help with your 5-bnc monitor. The key
question is whether or not the video card can produce a sync combination
palatable to your monitor. I believe the A2094 uses a 72-Hz vertical rate
to produce 1280x1024. at 72 Hz, that exceeds the capabilities of most video
DACs as normally found on PC video cards. Knowing that, I'd not expect to
find a card for just a few dollars (few meaning <<1k) which is up to the
task. Most current generation video boards interlace the 1280x1024 at 83 Hz
in order to stay within the DAC's capabilities.

I have found a manufacturer that seems to have an adaptor to allow me to use
my HP A2094 monitor with my standard PC for only $30.00.
Could this actually work ?
I am not a monitor expert so could someone tell me if this could work by
adding composite sync on pin 13, and on green pin 2 ?
Looks to me that It would only be MONO if this is done ?
Here is the information from their site:
PC Sync Adapter (Cost $30.00)
HD-15 Male to HD-15 Female adapter provides
composite sync (pin 13) and sync on green (pin 2).
Here is the standard pinouts for a VGA video card that I found:
VGA DB15-S Female DB9 Female
15-pin 9-pin assignment
1 1 Red
2 2 Green
3 3 Blue
4 - Monitor ID bit 2
5 - N/C
6 6 GND (red return)
7 7 GND (green return)
8 8 GND (blue return)
9 - N/C
10 - GND
11 - Monitor ID bit 0
12 - Minitor ID bit 1
13 4 Horizontal Sync
14 5 Vertical Sync
15 - N/C
>Yes, this monitor has analogue RGB inputs with separate syncs. But the

>(Xfree86 could probably do it if you run linux).

Info I have found says it runs 1152 X 870 at 75 Hz
I seem to be getting several different opinions on the HP 19 inch monitor.
