We're succesfully dumping the DG/UX tapes we have here. :)
we had a lot of problem due to "Sticky shed syndrome": the
tape stick to the head, causing the tape to lock while
reading data ...
cooking tapes will be a solution, but we followed another
idea: we used a special Teflon Lubricant Spray (here in
italy is "CRC TEFLON PENLUB SPRAY"
this is PERFECT for tapes - we had to rewind the tape
spraying the lubricant on the tape. this cause no
problems at all, and we red sticky tapes without
problems!
the tape images are here:
http://zaverio.net/eclipse/stuff/TAPE-IMAGES/
i don't know if there is (C) on those tapes - and really, i
don't care about it. I think preserving them is a MISSION for
us, and, so, here are the images.
happy hacking! :)

well,
we discovered that we have MV/UX installed together with AOS/VS,
so we have a weird UNIX running ... under AOS/VS
:)))
so, our goal is, for now, to preserve the actual system, and
to make a copy of the tapes (now we can use "dd" to read/copy
them)
we're experimenting, stay tuned
we wrote some documentation in http://zaverio.net/eclipse/stuff,
and we will put online some help ASAP
p.s. any help/hint appreciated :)

well,
another great day! we booted via tape! :)))
the problem was that the eclipse need to load the "MICROCODE"
before read anything else; and we had 2 problems:
1)
the tape head was so dirty that we can feel the dirt on
the head touching with a finger! after cleaning it, the
tape reader now perfectly!
2)
the microcode original tape is ... in horrible conditions! it
release magnetic particles touching it, and the tape reader
can't read it :(((
BUT
we found that a microcode copy can be loaded from the hard
disk (a 550 mb disk, very big and huge ! :)
so, we can now load the microcode from hard disk and, after
that, boot the DG/UX installation tape :D
AND WE'RE SO HAPPY, SOOO HAPPY, WE LOVE ALL ! :)
the main problem is how to do a backup of the whole disk,
to preserve the original AOS/VS installation, before trying
an installation of DG/UX.
Any hint? :)
p.s. some images here:

many tnx to eflags for the help (he's the guy in the photos).
It's a sort of JESUS. He touch hardware imposing hands, then
the hardware magically works.

Hi,
Sorry if this is spam but in a flash of "well, duh!" insight I realized
this is the right place.
We're looking for systems people and we really like minimalists.
What I tell people when I hire them is "If it's in the 1986 SVID or if
it is sockets or mmap, you can use it. Anything else is off limits".
And our code works everywhere, we can bring up a new platform in about
an hour and our source base is not trivial.
We're all C and bourne shell (ok, yeah, some tcl/tk for guis). We're
hacking bwk's awk source base (he sent me ~bwk/awk with all the source,
tests, the source to the book in english and french, gotta love that)
so we can use it to be the front end to our simple database (if you
think about it an SQL select statement looks one heck of a lot like an
awk program). It's pretty cool, we're making a scripting language for
systems people that is small. Kind of what perl would have been if it
had been part of V7. Oh, and the language is going to be open source
if that's important to you.
We are looking for a few solid programmers. We pay well, we're
profitable, no debt, no outside investors, stable revenue stream, and
we're growing. Our growth is limited by our ability to hire which in turn
is limited by my taste. Which is very much in line with this community,
small is good, simple is good, complex sucks. We live and die by Brian's
comment that debugging is harder than coding so if you were clever when
you were coding you are by definition not smart enough to debug the code.
What we have to offer is a stable place to work, no crap from idiot
managers or money grubbing VC's. What we are working is cutting edge,
ping me for information, it's more than what is publicly known.
We're in the Bay Area and we want you to be too. If it's a fit we'll
pay to relocate you.
Please let me know if you are interested. And if you aren't but you
know someone who is a good fit we'll cough up a $10K referral fee
provided that they last at least one year here.
Thanks,

Compiling vtserver gave me an error:

This due to the way errno is now used; errno.h has to be
included.
Here's a patch to compile vtserver 2.3a-20010404 under linux:

maybe this can be included in ftp://minnie.tuhs.org/pub/PDP-11/Vtserver

p.s. i'm not so good in C, i quit programming many years ago, i
hope this can work ok :)))))
hope all this can help.

Hi,
here we are back from pdp-11/34 restoration. We haven't
installed unix, because we have to prepare a special
disk image for V6 to be installed on the RL02 disk
(only 10 megabytes :)...
now we're working on the Data General we have at our
lab in Palazzolo Acreide, a little town in Sicilia
(http://poetry.freaknet.org)
We had an hardware problem some time ago - the tape
had some electrolytic condensers to be changed, the
fuse blow out, ecc. ecc., but now we think the main
electric part is OK, because the tape start, and
try to load the tape ... but
using CLI to boot the tape, we have this error:
SCP-CLI> boot
Boot from what device? [24]: 22
Fatal System Error: Data Channel Bus Timeout
AC0 AC1 AC2 AC3 PC CARRY ATU
00000000044 00000200000 00000170360 37700000000 00000000000 0 OFF
SCP-CLI>
can someone help? We have original DG/UX tapes here, and
we want to install them on our disk, that now contain a
weird AOS/VS installation (and we have some backup of
it in other tapes)
sorry for spamming the mailing list - but this list is our
only resort :)
(and i apologize for my bad, "italian way" english language :)))

Wow, thanks for posting the pics, MAJORLY cool !
it's incredible,
after 3 years, it BOOTED !!!
the images, taken some minutes ago, are here:
http://zaverio.net/pdp11
it's INCREDIBLE
we removed the cpu boards, we looked all the chips in it ...
eating pizza and sicilian food (you can see it in the photos),
and we re-inserted them ...
and, just for a desperate test, we tried CTRL-BOOT ...
and, THE CPU was RUNNING! so we tested all the console
cables ... that seem not working ... we found another
cable, with a null-modem converter, so we connected an old
IBM terminal ...
and, it was incredible, we had the CONSOLE CURSOR!!! :)))
NOW,
the next step is to FIND what was faulty ... a false contact in the
board connectors ???
any other hint? :)
p.s. tonight we want to install UNIX. :D
