Hello to all HP-UX fans.
I got one HP C8000 but my 2003 HP-UX 11i.v1 CD
fails to install.
Can anybody inform me where to get the
proper version?
HP workstations are licensed to run HP-UX
so that should not be an issue as far as I know.
Download of image would be all that is needed.
BR, Matti

Content-Type: text/plain; charset=us-ascii
Has anyone managed to create schematics for the display and power supply for the
HP-85A/B? I don't know yet if Tony's schematics for the 87 are applicable or
possibly close enough for these boards.
I have both an 85A and 85B with identical display issues, which I expect are due to old
capacitors causing poor voltage regulation and/or ripple. The pincushion test looks
pretty good, except for a bit of vertical displacement (think low amplitude waves) on the
horizontal lines. The second issue is when a lot of white is being displayed (i.e.
reverse video), there is a distinct narrowing in the scan line width in the top inch or
so, with the narrowest at the first scan line. Then there is a gradual widening towards
the bottom, with the lowest scan lines ending up off the sides of the phosphor.

Meh, I think not. I'm trying to cut down on the number of different
platforms I have to maintain, not add another. ippool also wouldn't really
be a suitable replacement for the way I use ipset, and the idea of trying
to use pf in place of ebtables and iptables for bridge-mode firewalling is
very unappealing. In fact, if I had to switch to something else, I'd
probably go with OpenBSD (which I already use for other stuff) over NetBSD
given OpenBSD's hardware support.
I plan to stick with Linux for most embedded applications, but the
widespread assumption by many userspace "developers" that everyone has 4GB
or 8GB of ram and a 2TB hard drive isn't helping anyone except help
hardware companies sell newer gear year after year.
Right now there seems to be a gap in the market for a Linux distribution
tailored for small/embedded systems which is also easy to maintain/update
with a halfway decent package management system. I have nothing against
pkgsrc, Ports, etc, but when you are dealing with lots of different
systems, and especially those with limited CPU/memory/storage, compiling
everything from scratch (as with Gentoo) just isn't a viable solution.

Yes. In my case I've changed the older J11 to one of the last available
revisions (-09?) to be at least sure that it meets the specifications.
I don't had another FPU Chip so the FPU and the Gate Arrays are the 15Mhz
Versions. Tested the entire Machine with all available Test Programms on
xxdp to be sore the entire system works as expected...no error so far..

**************************************
I get my belts at turntableneedles.com. They have
a wide selection of belts and a good cross reference.
Oh, and they carry turntable needles too.
:-) Thanks, they look useful. This is an old Admiral unit (good ol' 70's
styling, and dreadful internal build quality!) and things are hampered by
the fact that they seemed to re-use the model number for a later turntable,
making searches difficult.
Because the drive pulley is crowned I can't use their string method, but
I'll be able to get calipers on the pulleys and work out the belt length
using their diameters and distance between them.
cheers

This is a non-issue publicity stunt. We already cleared that up in our
book "Atari Inc. - Business Is Fun" released last fall, going by
direct interviews and actual internal documents.
There were never thousands of ET games buried in Alamorgodo, that's a
myth that sprung up later and was also never once mentioned by the
actual press articles of the time. The dump there was simply a
clearing out of Atari's Texas manufacturing plant as it transitioned
to automated production methods and a focus on personal computer
manufacturing. It had previously been one of the main plants for
manufacturing of game cartridges and other hardware, and game
manufacturing was being moved overseas to China.
As part of the transition the unused cartridge stock of a group of
titles (not just E.T.), console parts and computer parts were all
dumped there in New Mexico. It was covered in detail by the Alamogordo
press at the time as well, and is just such a non-mystery that I'm
surprised by all this.

The RICM has a bunch of RA81 drives that don't generate the pulses from the

No, the HDA was stripped bare.
I do have the spindle.
I also have 3 RA82s and another RA81 (that goes to Dave McGuire once we

Please bottom-quote. It's dead easy in Gmail, even in "new compose" -
just press Ctrl-A to "select all" then trim & reply beneath.
Anyway, reading between the lines, it seems clear where all those ETs
went, anyway.

ricklewood are useful to me becuase they're near enough for me to go

Because the drive pulley is crowned I can't
use their string method, but
I'll be able to get calipers on the pulleys and work out the belt length
using their diameters and distance between them.
Reminds me of soemthing I wrote i nthe HPCC magazine when I described how
to repair the HP9810/HP9820 internal card reader. The belt on that is a
simpe O-rign running on grooved pulleys
Toe find the size of the O-ring, I said that a practical person would run
a bit of string round the pulleys, mark it and measure it. A calculator
hacker would measure the diameter of the pulleys and the spacing between
the spinles and use the belt length program in the HP67 or HP41
Mechancial Engnieering Pac. As I then went on to say, I am both, so I
did both. Fortuantely the answeres agreed to within the accuracy of the
measurements. Even more fortuately that size of O-ring works in the reader.

Have you looked at the hardware and the system tracks on the disk? This
thing, for all it claims to be the disk drive for the HX20, etc, is
actually a full Z80-based computer running something very close to CP/M
(!). I often wonder how hard it would be to use it as such (there's a
second serial port too, if you need it).
Yes. fasinating. I am trying to disassemble it, but started with the
boot ROM. The TFDOS as it is called, will be next. As it has everything; enough RAM, disk
controller, serial port, there
should be no reason why it should not work. I might try it, maybe even
before retirement ;-). With the information in "The Programmer's CP/M
Handbook" it should be no problem.
It should eb fairly easy. There's absolutely nothign custum on there. All
standard chips, easy to get data sheets for them. A schematic exists, so
figurign ot uthe addresses of the I/O devices is not hard either.
I have never looked, there is that second serial port at TTL levels (th
TXDB and RSDB piads on the serial daughterboard). Does anything ever come
out of there in normal operation?

Only this evening I realized, based on your remark on the extra serial
port, that channel A is used for both host (HX-20) and 2nd TF-20 and
channel B is not used. So connecting my TTL-to-USB to the TXDB and RXDB
and boot the TF-20: alas no output or any reaction to Enter, Esc or Ctrl-C.
By now I know the boot ROM does initialize channel B, but does not write
to it. Apparantly TFDos doesn't either.

I just realised that perhaps Maplin do have some of what I want, it is that
they aren't listed as 32mm, but as 1.1/4. But they don't have the 375mA one
(although my machine actually had a 315ma one, but Maplin don't have that
either), the nearest is 250mA.

If you're looking for small quantities of replacement belts, check out
the eBay seller "isellprojectorbelts". He's got quite an inventory.
If it's a "price is no object" affair, try
http://www.bpbincorporated.com/about.htm
Their minimum order is about $125, but they can make belts to order.

for something like this?
The lack of i386 support with TC isn't very encouraging, either (they
state i486 as a minimum, which is the same as modern Debian, et al.) I
have boxes upon boxes of i386 stuff and I'd hate to at some point have to
create a separately maintained fork of the Linux kernel just to keep them
supported (everything from Intel 80386SX-16 to AMD 386DX-40, with and
without FPUs). The idea of using either an obsolete (and likely
unmaintained) Linux kernel or MS-DOS on them isn't terribly appealing.

Not *all* of them. Have you tried TinyCore?

The base system is about 12MB:

There's a text-only 8MB version:

What you are looking

NetBSD is the reference implementation of The Unix Paradigm.
Linux used to be a free Unix for Unix enthusiasts.
Today it is a bad Windows (MacOS X) surrugate for point and drool lusers.

What you are looking for is NetBSD.
Maybe. In particular, if you want 386 support, you'll be stuck with
older versions. (Mind you, I personally don't see anything wrong with
that; I run 1.4T on those of my machines which don't need something
newer for hardware-support reasons.)
\begin{troll}

Troll indeed. :-)
I'd say it _once was_ the reference etc. It's been headed downhill for
a long time, though; I now see it as trying to take on Linux at its own
game (desktop market share), and, of course, losing - and, in the
process, alienating the user base its former strengths attracted.

More interesting than the Apple I IMO is the
SCELBI-8H listed on the
same site:
computer-1973
Looks like it was sold on the same auction day.
If anybody sees what

\begin{troll}
NetBSD is the reference implementation of The Unix Paradigm.
[W]hen you are dealing with lots of different
systems, and especially
those with limited CPU/memory/storage, compiling everything from
scratch (as with Gentoo) just isn't a viable solution.
I don't see why not; it's how I set up my own machines.
...well, I don't know how limited your "limited" is. I have a few
machines too small to self-host; those, I simply don't run a
full-fledged OS on. Perhaps this stance simply reflects a gap in my
computer collection, the sort of thing for which 256K or 512K of RAM is
a reasonable memory load - I don't really have anything between the
really tiny machines with the likes of 256 bytes of RAM and 8K of flash
and full-blown machines with 16 or 32 megs of RAM and at least a few
gigs of disk.
