Looking for documentation for the Dilog DU-686 Unibus ESDI controller.
Anyone have scanned references for it, or possibly just able to forward
me jumper and on-board configuration connection and set-up info?
TIA,

Re:
"I just built a new PC, I didn't even think about ports. I personally have
very little use for Parallel ports, and am more interested in Serial ports.
I didn't even think about it not having a Serial port until I was finishing
putting the system together. At least it does have a header for a serial
port on the Motherboard, I'll just have to find a port to connect to it (as
that didn't come with the board). Oh, and the board does have a Parallel
port."
Let me guess: Asus P5B? I chose a Gigabyte GA-965P-DS3 instead of the P5B
primarily for just that reason (the boards themselves are nearly identical).
The P5B uses one of the two "standard" cables. Look on
alt.comp.periphs.mainboard.asus about 60 days ago and you will find a
discussion of this, along with the specs for the cable (there are two
"standards" for this cable, different and incompatible, so you need to get
the right one).
I can't believe Asus' stupidity in not putting the DB-9 on the I/O shield OR
at least in not including the cable to the header.
I admit, I cut my teeth on that machine and so I continue to ask around
for remaining tidbits. My friends at Tymshare don't have bits apparently
and I wasn't around when the 940s went out the back door.
Al K. has my copy of the monitor (kernel) listing; that could be OCR'ed
but what about the executive and all the other stuff?
But the real question is: What does MUL =12525253B do?

If the contents can be identified, consider some form of checksum per file.
Eventually, as multiple copies of the same discs are found from different
sources you can verify file integrity.
If they are original distrib discs, checksums of the entire volume can be
used for disc integrity (and for simple checks for viruses on newer media)

If I understand their business model, they charged a premium, but what
the customer gained was a single place to go (one catalog, one vendor
to send POs to, etc), and some "big name" reassurance.
In my experience, large companies deal with small companies poorly or
not at all. If a small company comes up with a nice comms-related
widget, they can try to sell it themselves with potentially mixed
success, or sell quantities in black enclosures through Black Box and
get instant exposure when the next catalog comes out.

I'm not familiar with that one. We had several analyzers (HP) and
BERT boxes (bit error-rate tester?) when I worked at Software Results
making sync comms hardware - fortunately I got to take my pick when
the doors closed. I still have a bunch of that kit, and it's still
useful since most of the gear does async as well as sync.
If your analyzer only goes to 38Kbps, it's probably async only. Sync
stuff I've worked with, tended to go up to 64Kbps or even 128Kbps (if
it wasn't designed for T1-like connections).

Sounds like you'll be busy for a long time with
archiving all those disks.
Do you have any ideas what you will call the
site with the archive? Perhaps you should
announce a beta version (when it's up and
running) for us to test?
I generally cataloge my 3.5" disks (mostly
Amiga, some PC and a handful of Atari ST disks) so I
can find programs I want fairly quickly.
Having approx. 600 disks I really need to do
that, otherwise I'd be searching for hours :(

This machine was the last host to be named AI.MIT.EDU that ran ITS,
and probably the last running DEC 10 or 20 at MIT (though that might
have been MC).
It comes with an ITS disk pack (and a drive). Might also have TOPS-20.
Bidding is at $2k so far.
--akb
ps: AI, MC, and the hulk of a third 2020 which I think was BLT (Brave
Little Toaster) were part of extensive hacker rescue efforts in the
early 90s. They were schlepped out of MIT, sat at digex.net for a
while until the VC-installed managers almost junked them, then CZ
rescued them and has cared for them since. (I'm not sure what he's
done with MC, BLT was mostly just the chassis and prolly got
scrapped). In the auction photos, those small red tags next to the bar
codes are the MIT "deactivated property" tags.
Okay, it's not quite typical fodder for here, but it seems to me to be
close enough to count as on-topic.
Two friends of mine (okay, a friend and an acquaintance) have a pinball
machine. But it's sitting in a barn and they'd like to get it in the
hands of someone who'll use/appreciate it before winter hits (it's been
there for a few months, but this would be its first winter).
I've never seen it myself. Here's what I've been told:
It's a "Data East Robocop" machine. No date apparent to the person who
looked (whom I'd primed to look for a date). One piece of glass is
shattered; from the description, it sounds to me like the backglass -
the vertical glass with artwork in front of the scoring and status
displays at the back of the machine. I'm told it's also functionally
broken in some minor way, but the person who characterized the
malfunction as "minor" is no pinball expert, so I have no idea how
accurate the characterization is. I also have no better description of
the malfunction.
The machine is near Ottawa (Ontario, Canada).
So, my questions: (1) is it worth anything in its current shape, or
does the damage (and/or maltreatment) cut its value to the point where
it's comparable to the cost of hauling it away? (2) anyone have more
specific relevant questions that can be answered by someone not versed
in pinball machines or electromech devices in general?
Oh, and (3) anyone want it? :-) (I'd be tempted myself except I have
no place to put it.)

Yes, 24 bit machines did exist. In fact before BSD, there was project Genie
which made an SDS 930 into an SDS 940 (added paging hardware) and made up a
timesharing system. It was the basis of the Tymshare corporation which was
formed in the 60's. The machine had (IIRC) 64k of 24 bit words, paged in
chunks of 4k words. The technique used what they called "relabeling registers"
on the upper 8 bits of the memory address. The software had all sorts of
things, including 'forks'. All before Unix (1969). Quite a system for its
day. It was the competition to the GE 235 (Later 635) machines that started at
Dartmouth. In the early 70's they had a whole bunch of machines in Cupertino
under one roof.
As for strings: They packed 3 to a word (usually).
Trivia: 'BRS 131B' was the system call to crash the system.
Just so you know.

I guess the question on many peep's mind is whether a

I need to do some reading. Maybe should have done it
first.
I hope this isn't off-topic :O
