Hi all --
Picked up a Vaxstation 3100 today at the SRCS meeting. There is some
minor corrosion on the memory and motherboard PCBs, some due to
prolonged exposure to moisture, and some due to a leaking clock
battery. I've cleaned up the corrosion and it doesn't appear to have
done any serious damage.
At POST it identifies itself as a KA42-A, which I believe makes it a
Model 30.
I'm getting error messages from the POST and I'm unsure how to interpret
them -- the manuals have not been 100% clear. Here's what I get:
KA42-A V1.3
F...E...D...C...B...A...9...8...7...6...5...4...3_..2_..1?..
? E 0040 0000.0005
? C 0080 0000.4001
? B 0010 000C.0081
?? 1 00C0 0011.700E
The (E) error I expect since there's no clock battery. The (C) is also
expected since I don't have a keyboard/mouse plugged in (just using the
serial console). Similarly, (1) is also expected since I don't
currently have the ethernet interface hooked up to anything.
(B) is what's confusing me -- my understanding is that a single question
mark indicates a "soft" error, described in the manual thus: "Usually, a
question mark (?) in the power-up summary indicates a soft error and the
system may be usable without replacing any FRUs." OK. What does that
mean for memory, and how do I interpret the error code? I know that the
"000C" part indicates the amount of memory installed -- what does "0081"
mean in this context, and should I be concerned?
For further reference, "test 50" gives the following for memory:
? MEM 000C.0081
00400000
The machine does boot (VMS 6.0 off of two very noisy 104MB drives) and
it seems to work OK, though I haven't stressed it much yet.
Any suggestions here would be much appreciated.
Thanks!
Josh
hello every one,
is the a tool to make proms from *.bin output from compilers?
that is to say a program that divides the 16 bits into two slices of 8
bits to make proms?thanks

SUN collectors,
This announcement below just came out on the SwRI internal
email. I don't know how they'd feel about buying an outside machine;
pretty sure they'd be OK with borrowing it if you are.
Let me know if you have a suitable machine to lend/rent/sell,
and I'll talk to the Division 9 folks to see whether they are
interested.
We are in San Antonio Texas, 78238
Division 09 is in need of a couple of Sun Ultrasparc 2 systems. An
Ultra 60 or better is preferable. The following system specs are
preferred, but all offers would be appreciated:
1GB of RAM or more
30GB HDD
10baseT, 10mbps Ethernet or better.
Solaris 8.

Hi all,
I have a pile of Mac serial cables that I have no use for. See:

If you want to save them from the recycle bin, make me an offer.

I was wondering if any of you who are running gopher servers might be
interested in hosting a mirror of the Interactive Fiction Archive. See
http://www.if-archive.org/.
I got back into the Frotz codebase and this thought popped up.

Today, 11-11-11, seems like a nice day to announce the availability of
yet another PDP-11 implementation in VHDL.
I have created a website for my project, PDP2011 ? a re-creation of
the well known series of PDP-11 computer systems in VHDL. After nearly
four years of work, the project is almost finished; you can run a
complete Unibus PDP-11 system with console, disks and other
peripherals on a simple low cost FPGA development board. Original
operating system software, like V5-V7 versions of Unix and BSD 2.11
work.
I would like to invite you to come to

Ignore the half-baked stuff.
Fully baked seems to still be in progress. (I think Buck Henry was responsible for that line in The Graduate).
Progress is very slow and what progress there is, isn't really due to any of my efforts (don't have nearly enough time to play with -11's anymore) but to others.
Apache here is doing weird-ass stuff and serving up random alphabetical URL's as stuff that just happens to be in various public_html directories on my servers (apparently sometimes from other virtual domains...???) but which was never intended to be public in that sense. My fault for not understanding what Apache is doing.
Good evening to all DEC-Enthusiasts,
stumbling around the internet and my own archive I wondered about the
RSTS/E Distributions later than 9.6. I'd like to play with one of the last
versions but nothing seems to be available. Somewhere I had read about
licensing issues and the Mentec Discussion here. Does anyone know more of
the current RSTS/E Licensing status? Or even has a
distribution/documentation scanned? Any help with this questions would be
greatly appreciated!
Regards,
Wolfgang

Hi,
Does anyone have a schematic for the Rhino Mark III Controller? I acquired
a Rhino robot arm and the B motor encoder channel seems to not be working
properly and I'd like to try to isolate which parts of the controller board
are unique to the B channel. Alternatively, if there are any Rhino
experts that could help point me in the right direction, that would also be
appreciated.
I think I've isolated it to a problem with the controller and not the
motor/encoder or the teach pendant. Using a scope, the output from the B
channel is very different than the other 7 channels.
Thanks...Win

Presumably it says VS42-A on the back of the box?

Perhaps it is complaining about an error which is correctable by ECC?

I've had a quick look in Vaxstation 3100 Maintenance Guide (EK-285AA-MG-001)
and it doesn't seem particularly clear to me either. It doesn't seem to
mention 0081 at all.

Under VMS, does SHOW ERROR or ANALYSE /ERROR (given an early enough version
of VMS) shed any light?

The manual does suggest running the field service system exerciser
(TEST 80000106 B) with a loopback connector on the serial port. Assuming this
is an MMJ socket, you just need to loop DSR to DTR (ie the two outer pins),
RXD to TXD and the two grounds in the middle to each other.
If any of the memory is on an expansion board, try removing it and repeating
the test to see if the problem is on the system board.
(I've had some battery corrosion problems in a VS3100. It doesn't look too
severe but test B seems to fail in the middle and go back to the start, repeating
over and over. I must get around to making a better attempt to clean it and
check the traces.)

Peter Coghlan.
