TSIA :)
I was skimming through the 11/34 manuals, and some confusion about the
termination of that system made me re-read through the M9312 manual.
Something doesn't seem right and points to me not understanding something. I
seek enlightenment from the list.
As I've understood things, you have to terminate both ends of the unibus.
Let's say you're dealing with an 11/34 with no expansion backplanes (ie.
just a DD11-PK). According to the 11/34 manual you put the M9302 terminator
in slot 9AB. That makes sense, it's the unibus out. All the other AB slots
are MUD (except slot 1AB, and we'll get to THAT in a moment). So about that
other end of the bus now! The manual states you need a M9301
bootstrap/terminator just after the processor (typically, it may be further
down if you have the FP and/or Cache options). That also makes sense to me,
gotta terminate that "near" bus end. I had a M9302, but I didn't have a
M9301. I wondered if I could use a M9312 in place of the M9301. So...
I skimmed the M9312 bootstrap/terminator manual, and sure enough, it
definitely talks about being able to use the M9312 instead of a M9301 in a
processor that "has bus termination built into the cpu such as the 11/04 &
11/34". It even says that you must set the jumpers on the M9312 to remove
it's termination capability, because in these specific processors the cpu
provides bus termination. Ok, great. I can use my M9312 in place of the
M9301 long as I jumper it as described. But... now wait a second! This gives
rise to my first question. If the cpu is providing termination, and if you
are going to use a M9312 on the near side you have to "jumper off" the
M9312's termination ability... then WHY is a M9301 called a "bootstrap
TERMINATOR". It must NOT be a terminator, just a bootstrap rom card. Right?
It seems to me that if the cpu is providing the termination on the near end,
that it is always doing so. Not JUST when you pull out the 9301 and put in
the 9312. What gives there?
That gives rise to my second question. IF the cpu is providing unibus
termination on the one side... why can't you jumper the M9312 to provide bus
termination and just put it in slot 9AB? You would get the other end (unibus
out) terminated AND get your boot roms as well. This way the M9312 would
replace both the 9301 AND the 9302. A few people I mentioned this to said
you can't do that. But given the above... it seems logical. What's the scoop
here?
Clarification is much appreciated!

I did, in fact, use snipeswipe on that auction. But he had a higher
bid in place than my snipe. Like I wrote, it wasn't losing the
item, that didn't surprise me as my bid was low. It was being
emailed by this guy who clearly didn't want the item, he was just
outbidding others so he could turn around and charge them more money
that it would have cost them if his sorry chemical composition was
disassociated.

I think I experienced this first hand within the last year.
I bid on a Fujitsu magneto-optical drive. Ah, here's the URL still
on my Snipeswipe page
<http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=8786740987> .
I was willing to go to about $16 (with shipping it would have been
closer to $30).
After the auction, the high bidder had the gall to email me to tell
me that he sells items of the type I'm interested in and that I
should visit his store. Of course, he sells MO drives for well over
$100.
So this creature outbids me and then tries to turn around and sell me
the same item at a higher price. If I had been willing to pay more,
I would have bid higher.
I can't point out some way in which this behaviour is morally wrong,
but it is certainly irritating.
Jeff Walther
Make them an offer. There seems to be group of sellers that list things at
prices that would have been apropos for a depot repair kind of outfit before
eBay existed looking for the "OMFG I have to have that part" hit, but are
more than willing to listen to deals offline.

I don't know about the timeline of Silent 700s, but I seem to have a few of the
bulkier ones in my garage (near San Jose, CA) complete with cassette tape
drives if anyone wants to "take them off my hands".
I even have a manual somewhere. I've also got some of the smaller ones (with
built in acoustic coupler) but I'll probably keep that one (unless offered some
$$$). If interested, contact me off list.
They were introduced in the 70's (75/76?) as I remember. If you had your Bell
103 modem (I have one of those, another story), they were pretty neat things
for "offline" editing of text files. Not exactly a vi editor, but better than
paper tape (that's not saying much).
Pretty reliable as a "hard copy" (thermal printing) terminal. Now days, you
can use thermal FAX paper in them and it works OK. Great to hook up to your
DP-8 or something of similar vintage.
Just a few facts.....

Is it just me, or is it now impossible to solder properly with "lead free"
solder and "lead free" flux?
Is there a decent make of flux available (like you used to get in those
little round metal tins, and is nicotine brown in colour), rather than that
utterly useless white water-based stuff?
Also, while I'm ranting, the white rubbish flux I bought (to try to get a
recalcitrant wire soldered up) has more warnings than I've ever seen on any
product except peanuts before. Is it my imagination, or is it actually more
dangerous than the stuff it's replaced?
Grrr

(PS: This has nothing to do with terminals - I was fabricating a new battery
pack for an Epson PX-8, due to the terminal expiration of the original)

Hello Jesse,
I do not longer collect them, the museum is defunct. I will forward
your message to the classic computer collectors list, by CC.
Thanks,
Patrick
TO CC members: please contact the gentleman "Jesse Bunch" directly if
you have an interest in the below described equipment. The pro380 as I
recall is quite a nice box and the 350 is nothing to sneeze at.
Thank you,
Patrick

Hi folks,
today I digged out some PDP11 modules. I wonder what I can do with them.
A Plessey-labeled Unibus Box with 11/34 front panel (the simple one) is
still waiting to be picked up by me or put to scrap...
Ok, what I found:
* DEC M8265+M8266 (11/34A CPU), M9301 bootstrap/terminator
Question: Is that enough to get the machine going? Do I need anything
else (except memory and a kind of tty interface)? What about the "parity
controller" which I don't have?
* Plessey PM-DC/11 "status control", P/N 700485-100C
Plessey PM-K11 "disc control", P/N 700490-101E
Plessey PM-K11 "data control", P/N 700475-100B
Plessey PMDC/11 "bus control", P/N 700470-100B
These are four quad wide boards. I have no clue what they are/where good
for. No connectors. Some DIP switches.
If anyone could help me out with some information and/or docs - would
be great.
* Plessey PM-DC1100, P/N 703380-100H
This hex wide board looks like an Unibus SMD disk controller.
If it's that I am VERY VERY VERY interested in information about that.
At the place I found the parts there is still an SMD drive....
It has three 26 pin ribbon connectors and one 60 pin connector.
* Plessey memory board (?!), P/N 701830-100G
Some information about that would be great. If anyone has something to
share....
Ok, if anyone can help me.....
All the stuff is available to anybody urgently needing it.
Good night,
Philipp :-)
Of course it's not decimal mode the way, say, a 6502 would do it but it's
interesting to see a major architecture bring back non-binary-based operations
(in this case base 10 calculations to avoid precision difficulties).
