It's a 50's US Navy instructional film about the mechanical computers they used.
It's really eye-opening and very high quality.  (It gets to the meat about two
minutes in.)  For me, it demonstrated the analog/mathematical approach, in
contrast to the digital/logical approach I grew up learning.

It looks like the site linked above is a primary Web source for WWII and later
Naval fire control computer documents. It may be the original source for the
video referenced above, or certainly an earlier one.

These control computers used rotational position (radius vs angle) as means of
expressing an analog function. One input variable was a cam on a shaft; two
input variables was a surface on a cylinder. By cascading, you could have
several variables per output. The video series shows this, and the Navy
textbooks on the site above explain further.

Mechanical computers like this were "programmed" by manufacture; one design
equals one program. Electronic analog computers were programmed by wiring panels
and adjusting components, as well as by design or by hard-wire. Hybrid analog
computers, made the connections and adjustments digitally.

I knew nothing about the above, until I did some Web searching based on the
reference first given. It's good to see more ancient technology on the Web. In
this case, advanced WW II technology, digitized from books and films.

I'll follow up privately on this.

I think some of these are originally from the Historic Naval Ships
Association. There is a group of us ship geeks that are also trying to
save and archive the technology, bitsavers style.

There is also a class of fire control computers that used linear
displacement of levers and linkages, rather than rotation. These
machines were much cheaper to make, but not quite as accurate. And of
course, there were hybrids of all sorts. I had a small collecton of
small machines and assemblies at VFC East number 2.

Trivia - there are two Mk 4 Torpedo Data Computers still in active
service, in the Taiwan Navy. They have been in near continuous service
since 1946.

I helped rescue a linotype for the System Source vintage computer
collection
vintagecomputer.net/linotype/

I had to disassemble to get into my car, took five trips.  It took me
almost two hours to re-assemble and run a few test prints.  More
complicated that they look.

I helped move to System Source in Baltimore years ago.  The owner, Dave
Roswell I believe got a week's training on the thing to operate it.  You
can visit the place to see it in the middle of the exhibit area.

That must have been a lot of fun.  Did you have to make many notes on how things
were disassembled?

I was just a kid when I went with my dad to move one of these, so I don't
remember much.  But when I was watching the Linotype film with my dad, he went
on to give me all kinds of details regarding tricks and pitfalls during
re-assembly of these machines.

Two hours to reassemble? That's not long at all!  I guess it depends on how much
was disassembled?

Good to see guys here with ink and metal in their blood!

   Sounds great to me!  Definitely bring the AUI cables; I am short of those.

   Bringing along those HSZs would be fun, but since I'll already be
putting a VAX 7000 on a liftgate truck, bringing the rack with the
HSJ50s, drives, and star couplers isn't a big deal.  I may also bring a
small (heh) PDP-11 to put on the network to demonstrate heterogeneous
DECnet networking in addition to VMS' clustering capabilities.

   Now, I know you're about as much into games as I am, but we'd need to
show off some games at VCF, otherwise the non-technical visitors simply
will not be interested.  Are you aware of any DECnet-enabled
multi-player games that we could use to show off either clustering or
DECnet?

Umm, yeah.  I had a good laugh about the 5 car trips, knew something was wrong,
perhaps Bill didn't know what a Linotype was?. Then I saw on the last line of
his post that he did put it into an 18 wheeler truck.  So I kind of guessed the
machine might have been hoisted complete and  2 hours was the time it took to
plug it in and test it.  I didn't want to say anything to be polite, since I
don't really know Bill.  Then I saw your post and knew it was a joke.  I was
hoping nobody would notice.

Thinking about it now, the metal pot takes 6 hours to come up to operating
temperature.  My dad who knows these machines like the back of his hand took the
better part of 10 hours reassembling it.  And that's only because he knew where
every part fit and did not reassemble out of sequence.  He might be a bit slow,
but that might be because he's just got 1 leg.

Yeah, bottom line is I fell for yet another joke on this forum.

Well, I finally got an 8" Floppy drive working.  Wrote code to format, read,
write, xmodem upload & download to the Floppy disk.  I made up a CP/M disk,
don't know if it works yet because I want to refine my program to
read/write/format to give better error checking.

I did however get to read Jonathon's disk that he made.  It reads well enough,
but for some odd reason the file stored on it is not in consecutive sectors.

Does CP/M skew the sectors? or is this done at the physical level?

Let me explain.  I included skewing a disk at the format stage, so when I write
a track, I'm encoding sectors 1,4,7,10...2,5,8,11... on the disk.  ie, on the
disk the first wedge after the index mark is sector 1, then next wedge is sector
4.  With a physically skewed disk, software should be able to read sectors
1,2,3... in an efficient manner.

There's nothing stopping software from skewing sectors, in which case it would
be best if a disk remained 1 to 1.  Let the software translate sector 2 as
sector 4, then fetch sector 4.

I have not yet checked if Jonathon's disk is physically skewed, this is one of
the improvements I intend on adding to my monitor program.

   Yes, CP/M can optionally skew sectors.

   CP/M uses a data structure known as a "disk parameter block" to
describe a disk format.  It includes an optional pointer to a
translation table that is used to translate logical
monotonically-increasing sector numbers to physical sector numbers.

vintagecomputer.net/linotype/ - this is the machine I helped rescue.  I was
right down the street.  They contacted me and asked me if I wanted it or
knew who might.  I sent a message on classic cmp....Bob Roswell contacted
me and paid for the truck to haul it away.  I am pretty sure he spent a
good week working with a 40-year veteran of linotype maintenance to
re-assemble and train on how to use it. I also recall numerous spare parts
and equipment. I am sure if you go to System Source in Baltimore it will be
operational or close to it.

I can leave you guys with a Cisco AS500 (does DEC LAT, X25 and telnet).
It has 80 ports on it. Also I have a few AUI to 10BaseT I can leave for
you with MARCH.

I think I worked with one once (or part of one). It handled the photos for the
AP and we had to interface to it. 25v dc +/- centronics interface. I was told
it dated to the late 1940. The thing stunk like vinegar only stronger.

A coworker is cleaning up his office and produced from a dusty corner, a
box of envelopes, containing microfiche, of the VMS 3.3 source listing
dating from 1983 when the University was a VMS shop.

That kinda made my day.

I tried to secure them for the museum -- But he's holding on to
them...for now.

What is a Cisco AS500?  Do you mean SA500?  With this much advanced time to
prepare, I am sure you all can come up with a routing scheme that can
handle the job that was made before 1990. Although some dispensation for
minicomputers has been allowed, exhibit hardware should have been produced
before 1990, unless it's a minor part that is inconsequential to the
overall presentation.

    Linotypes don't deal with photos and have no electronics other than
that required to drive a single large AC motor and an operator's lamp.
They are textual typesetters, 100% mechanical, designed well over a
century ago.  They use no chemicals other than lubricating oil.

    You are likely thinking of a Linotronic phototypesetter or some sort
of copy camera system.

     Does this eliminate my VAX 4000/300 from 1991?  We (Dave and Sridhar
and I) had talked about including it in the cluster.

    The VAX-7000 I was thinking of bringing was introduced in 1994 and
discontinued around 2002.

    On top of that, VMS is still a currently-developed, fully-supported
operating system.

    I think this situation is illustrative of the fact that hard-and-fast
rules on "what is vintage" and "what is not" are unworkable.  We know it
when we see it...and the rumble of a VAX-7000 and a bundle of big thick
CI cables coming out the back, while still a fairly common sight in
datacenters today, very much embodies "vintage computing" as well.

    However, if people would prefer I bring something else, I fully
understand.

What is to be routed and to where???

I think that all of the systems could EASILY fit in a single DECnet area;
no routing needed.  Even if there would be a need, a VAX can be configured
as a routing node assuming it has a DVNETRTG license PAK.  VMS clustering
needs NO routers/routing.  All nodes must be able to see all other nodes
on the cluster interconnects.  I'm assuming these will be CI and LAVC.  I
could also configure SCSI as a connection.

    I was thinking CI and LAVC as well.

    PAKs are not a problem.

    I was also thinking of having a temporary area allocated to HECnet
(the wide-area hobbyist DECnet, all over the world!) to connect our
VCF-E network to HECnet for the show.  I think that would be lots of
fun, and would also allow the HECnet gang (a great group of folk) to
"participate" to some small degree in VCF-E as well.

    What do you think?

I thought you were bringing a VAX-11/780! :)

I can attest to that! ;)

However, while there is no more development on VAX VMS but it is supported
for those still with support contracts for it.

I'd love to see/do a big iron exhibit.

Especially if you know somebody with PAKGEN licenses. ;)

That would be way cool.  Talk around the world!

     Some folks prepping for this year's VCF-Midwest were talking about
connecting to HECnet.  I don't know if they succeeded, or not.

   Oh!  I hadn't heard about that, and it hasn't been mentioned on the
HECnet list.  And here I was thinking it was an original idea. ;)

   I just emailed the HECnet list about it, to ask the opinion of that group.

   Evan, what do you think?
