Ok, I got my PDP-11/34 mounted in its rack and have started to audit
jumpers, switches, etc. I am being cornfused by the M9312 bootstrap
terminator module.
First, I'm confused about what version of the module I have. My 11/34 user's
manual (EK-11034-UG-001 '77) talks about a -YA, -YB, and -YF version of the
board. My M9312 manual (EK-M9312-TM-003 '81) talks only in terms of
bootstrap ROM part numbers. The DIP switch references in the two documents
conflict, even differing on the switch settings necessary just to boot into
the console emulator.
My M9312 has no -Yx designator and has only one bootstrap ROM installed
(756A9 for RK03/05/05J or TU55/56). The M9312 manual seems to make the most
sense in this case, so I've been believing its side of the story. However,
the DIP switch settings on my M9312 have me puzzled. Here they are:
1 2 3 4 5 6 7 8 9 10
ON ON ON OFF OFF OFF OFF OFF ON ON
This doesn't correspond to anything in either manual! According to the
manual I'm trusting, this says to start executing at 765406 (in the console
emulator ROM). It needs to be 765020 (with diags) or 765144 (without diags).
Supposedly, the machine was functional when it was decommed, so my first
instinct is to assume I am (or the docs are) wrong somewhere. However, its
previous owner (another collector) was not able **IIRC** to get a register
printout at power-up. So maybe the DIP switch is pointing to someplace that
isn't a valid entry point. I don't have access to the complete M9312 print
set, which would list the ROM contents.
Should I reset the DIP switch to say 765020?

Jeff, I think I was eventually able to get the register printout, but I
don't quite remember what I did to finally get there. I ask for help here on
the list, and several people spent a lot of time helping me (thanks to all
of them, BTW) and I believe I did finally resolve the issue. I might still
have a lot of their emails telling me what to do, which might help. I also
still have some of the documentation, some of which has notes jotted down
specific to *that* 11/34. I don't have time to look right now, but I will
today or tonight and let you know.

New subject: Collectors List
Several years ago I set up a list of collectors on the TC3 site, which some
of you may remember. Subsequent to that site being shut down by its host, I
moved the list to my personal site at the following url:
http://www.geocities.com/SiliconValley/Horizon/9107/
The collector's list is reached from a link on the main page and resides at
this url :
http://www.geocities.com/SiliconValley/Horizon/9107/collectors.htm
The reason for this message is to request that anyone who is on this list,
contact me HERE :
antiquecomputers(a)hotmail.com
to update their information. I have recently sent out an email to all person
on the list, but find that almost everyone has moved ... email address
anyway. If anyone reading this wishes to be put on the list, I would be glad
to add their name and information, just be sure to format it the same way it
is on the list.
(None of this benefits me in any way, if anyone is wondering. However, since
I receive email almost every day originating from my site, it is a constant
source of information and resources for me. When someone has a computer for
sale or donation, they frequently email me and I refer them back to the site
to see if there is a collector near them. Most, of course, are from the
states and many, many of the requests are for good homes for donated
computers.)
PLEASE don't contact me through the list, use antiquecomputers(a)hotmail.com
only. I will repost this a couple more times, unless someone really finds it
useless.

I sat on this a bit gritting my teeth but I can't let it pass.
I was involved with this individual in setting up Toronto
Computer Collectors Club and he agreed to take part by
doing the site coding and putting the site in his name with
some contributions from others including myself, who
expended considerable effort in getting it going.
He then used the site to gobble up any computer
contributions in the name of TC3. He likely has the
largest collections of Hyperion artifacts in NA due
to the gullibility of well-meaning contributers of collections
to TC3. One of whom mentioned it would take a couple
of carloads for equipment and documentation.
Following the diclosure of this, TC3, which I had played
the main role of organising in order to have a center for
local Toronto computer collectors to get together broke
up.
I would advise collectors to stay clear of this guy since
based on my experience he would only use your
enthusiasm for classic computers to his own advantage.

Much as I appreciate the head's up, I don't see how this is
the state of affairs today. I listed my interests on his
website. It has *my* email address. How can he "gobble up"
contributions going to me???

Interesting take on history. Out of the original T3C, Colan and I still
interact while you have started spats with both of us. As for my using the
T3C site for my own purposes, I'm mystified as to why you recently forwarded
an offer of a donation to me. It wasn't a Hyperion, mind you, but, as you
say, I have enough of them anyway.
You're entitled to your own opinion, of course. Don't really see how listing
names of collectors all over the world is going to benefit me but maybe if I
squint my eyes and look through a glass of cheap wine, I might see what you
see.
You can flame away, Larry. This is it for me on this topic. Cheers!

Jeffrey,
are you sure the 11/34 manual is talking about the M9312? - I seem to
remember that my copy describes the M9301, of which, IIRC, there are
-YA, -YB, and -YF versions.
Since all M9301s are completely different from the M9312, it would be no
surprise if you cannot match the switches between docs and hardware...

Uh, oops... You are exactly right. The 11/34 manual is indeed talking about
the M9301 and not the M9312. I have a M9312. Problem #1 solved.
Mand that lysdexia!!!
The only thing now is to figure out why the switches are set as they are. My
unit's switches point somewhere in the console emulator ROM, but not at one
of the two valid entry points specified in the M9312 manual. Either:
A) That's the original ROM and wherever the switches point happens to
work as an entry point. The previous owner may have set them this way,
possibly to bypass some of the diagnostic tests.
B) That's not the original ROM and the switch settings are correct for
whatever ROM is now in there. The previous owner may have replaced the
ROM.
C) The switch settings are wrong.
Could it hurt to simply plug the board back in and try it out, assuming the
rest of the machine is OK?
