Wow. Thanks for sharing. What a beautiful looking machine. I hope one of us
gets it.

Not really a 026 but maybe contemporary with the 029:

Not mine.
I was wondering if anyone has or knows anyone who has experience with
low volume sheet metal enclosure fabrication? I am looking for a
fabricator to build small (think game cartridge enclosure sizes)
clamshell units (or similar).
I thought before I start cold calling folks, I'd see if someone has
already had some success.

So does anyone have a trashed/dead front panel for a Data General S/130
(S/200 would also work) that can be a donor? All I need are two
switches/paddles/Covers, but my S/200 front panel is perfect so I don't want
to rob from that for the S/130 project. One light blue, one dark blue...
Crossing my fingers.....

I decided to raid the front panel of my S/200 to get a switch cover and a
switch for the S/130; what can I say - I got antsy to see if the S/130
worked ;) When taking the S/200 front panel apart I found it really wasn't
in great shape as it had appeared to be from the outside. A large number of
the incandescents had broken off and were sitting loose and one of the
switch covers was broken so someday I'll return to the S/200 but the S/130
restoration was completed as a result.
Pictures (completely out of order) are at
https://www.flickr.com/photos/131070638 at N02 but the first picture shows the
cpu up.
Once or twice, running the microcoded self-test produced a "Rom Error", but
almost always it produces the desired result and loops on that test (checks
microcode checksum, ability to execute and step microcode, a few CPU
instructions & paths, and tests the lowest 16Kw of ram). Raising switch 0
halts cpu at microcode address 2 just as it should.
I also noticed that on rare occasion, hitting "examine" on AC1 produces no
result - but other than that I can store and read AC0-3 as well as several
different sections of memory.
Next step is to locate a 4045 board and see if I can get a console hooked
up. After that, I'll need some way to get diagnostics into the machine. To
that end, I could try restoring a HD, 8" diskette, paper tape, or dual
cassette drive - but I'm wondering if there is any previous art for entering
a front panel ditty and stuffing diags down the console port (from a PC)?
Yes, google is my next stop ;)
Thanks to several listmembers and especially Bruce for pointers and advice,
as documentation is scarce and not organized the way my brain works.
Best,
J
I'm pleased to be able to report the successful installation of OpenVMS
8.3 - Alpha on my 3000 M600
It now runs Dec Windows on the graphics screen and a terminal on the
serial port.
TCPIP works and I can get to my local network OK.
Now to find a browser. There must have been one

OK, there does appear to be larger disk support... now how about for RL02?
Unfortunately the drive is not as smart as an RK (can't do spiral
read/writes) so that would complicate things.
However, each side of cylinder 0 is about 10KB, so 20K is available without
having to move the drive head. I bet that would be enough swap area most of
the time (it's not like most of us have 16 users all logged on
simultaneously) :)

Actually, IIRC this was an 029 - thread drift, after LCM (IIRC) enquired
about a punch - for them, an 029 seemed as good as an 026.

Indeed, this whole list is about people saving computers that don't really
have any _practical_ use any more. By definition, from a purely _functional_
perspective, their value is scrap. But our viewpoint is not that - we see
them as interesting and historic artifacts - and in that light, their true
value is set by that old mechanism, supply and demand.
So some antique computers go for what I find remarkably low prices (e.g. QBUS
-11 stuff) because there's a good supply, and other very similar machines go
for a lot (that 11/70).because they are un-common. And IBM punches are not
exactly common items...

Yeah, that too. The easy recombination and modularization of malware
makes it so much worse. I suspect there are quite a few easy ways that
malware could hold hostage the typical VMware / Hyper-V / Veeam / NAS / SAN
setups at many businesses, and easy money because it would be far easier
to pay the ransom than to perform full disaster recovery.
On a more classic-computer bent, though, I try to look backwards
for wisdom about how this problem could be solved, and it's such a
different world with the Internet and higher stakes and dependency
on networked computers... it's not easy to solve.

Something like two and a half years ago, I got a copy of
EL-00032-00-decStd32_Jan90.pdf, a one-image-per-page scan of a paper
copy of the VAX Architecture Reference Manual. I don't know where I
got it, but bitsavers has a file of the same name with the same MD5
checksum at /pdf/dec/vax/archSpec/EL-00032-00-decStd32_Jan90.pdf now,
so it likely was there.
I played with trying to build character-recognition software to convert
it to text and eventually decided it would be quicker and easier to do
it myself.
I've just finished that. (I'm not sure whether it actually was quicker
or easier....)
The result is available from ftp.rodents-montreal.org in
/mouse/docs/DEC/VARM/EL-00032-00-decStd32_Jan90.txt for anyone who
would care to grab a copy.
