Just a quick note for now.
Resistive sheets belong to a category of analog
computing called network analyzers.

Fluidics (or fluid logic) can have both analog
and digital processes. You can perform boolean
operations, but you also can have fluid amplifers.

Most computer applications are simulations of one
kind or another, word processors, spreadsheets, drawing
programs, even a desktop GUI. Analog computers are the
masters of the art of simulation, but they are not used
for mundane simulations like these.
Analog Computers run mathematical simulation of physical
systems. Everything from the decay of subatomic particles
to the interaction of two colliding galaxies.
Do you want to:
* See the results of a chemical reaction?
* Test the design of an automobile tire?
* Study the effects of pollution on a fish population?
* Model blood flow through an organ?
* Understand the effects of lowering the interest rate?
* Fine tune the design of the Space Shuttle main engine?
* Control flooding on a major river?
* Explore new types of music?
All of these are physical systems governed by mathematical
equations.
Analog computers are PURELY parallel and can run programs
slower than real time, real time or faster than real time.
Simulations can be halted at any point and all aspects of
the simulation can be examined. Changes can then be made
and the simulation can then be continued from the point it
was halted or restart from the beginning. So, analog computers
can not only simulate a fixed systems, but can also test
'what if' cases very easily.
Analog computers can be a hardwired special purpose type or
flexible general purpose type.
The EC-1 with only nine amplifiers can be limiting in the
size of simulations it will handle. But analog computers
don't have the compatibility and the connectivity problem
of digital computers. Ten EC-1s could be connected together
to form an EC-1 with 90 amplifiers. The only problem would
be if more than 9 integrators were used then a slight
modification would have to be made to each EC-1 using an
integrator to allow one EC-1 to control the mode.
An EC-1 can also be directly connected to another brand
of analog computer. No problem other than the mode control
of integrators.
The lure of the EC-1 is that it a inexpensive and compact
example of vacuum tube computing.
The world is analog. The human mind is analog.
Digital computers make a nice hobby, and work just fine for
tasks composed of sequential steps, but they are just an
over hyped fad.

Hi Don
That is what I figured. I've been working on my serial
bootstrap and transfer program. I'm able to read and
write an image to the H89 but I'm still having issues
getting the formatting to work. I copied some old
code that I have in the Fig-Forth that I did but it
is still missing something. I even went back and ran
the Forth FORMAT and it works fine. I suspect there is
some other initialization that I'm missing. I looked at
one stretch of code and there is an operation that should
always hang. Can't figure why the original works. It
may be something connected to the timer interrupt that
isn't normally there. I wish I'd made good notes when
I did the original but this was one of my first computer
projects, after working on my Poly88, and brain rot
is now catching up with me.
Once I get the format working, I can work on cleaning
up the user interface. Looking at the 96 stuff is a
little later on the list.

I was looking around on the internet (mainly decdocs.org and linked
sites, as well as google) and I was unable to locate scanned manuals for
the Vaxstation 4000/90. If anyone has a link to such documents, I would
appreciate it.
My problems revolve around a newly aquired machine which does not appear
to be giving me console access over the MMJ port in the rear of the box.
As I said, this is a newly aquired machine, and I have not really taken
it apart yet, but the manuals would be helpful in any event.

Hi Jules,
To my knowledge the largest hard drive platter was 24". IBM the inventor may have produced
an experimental platter of ~1 m as a demonstration project to management and maybe these platters
were 'sold' or distributed to IBM employees?

I'm in Ottawa ON Canada. As far as I know, international shipping into
Canada is not practical, so I'm interested in antiques that happen to be
already in Canada.
I picked up the following items today while searching the thrifts:
SGI Indigo2 IMPACT cpu only no KB or monitor with it.
HP Visualize C180 cpu only no KB or monitor.
HP apollo Series 700 product # A2286A.
TRS-80 micro computer system Catalog # 26-01006-G. No monitor or power
supply with it.
Apple IIc Plus cpu only.
Tandy 1000SL cpu only.
NBA JAM cassette/cartridge for the Super Famicom.
Panasonic R E A L FZ-10 3DO console.
Hi all,
I got a TRS80 Model 100 in and need some technical info:
-what is the polarity of the DC-input on the socket?
-Is a filtered 6 volt DC voltage ok or has it to be stabilised?
-I found lots of recources on http://www.club100.org/
even a technical manual, this however does not adress this DC input.
Thanks,
Frank

Er, the gear we've been discussing is very small -- about 3mm overall
diameter, roughly the size of the winder knob on a small ladies
wristwatch! MUCH smaller than a small staple, in fact the bore's
hardly bigger than the staple diameter :-)
Anyway, Araldite doesn't stick to waxy plastic like these gears :-(

Enlarging the hole by 0.1mm would make it spin on the shaft :-)

While that's true for most modern *electronic* analog(ue) computers,
it's not a good generalisation. What about things like Vannevar Bush's
differential analysers, gun directors, Norden bombsights, various
electro-pneumatic or hydraulic computers, or the G-star analog

Hi
Another type of analog computers include mechanical ones.
During WW2, they used really complicated mechanical fire
control computer. One would input range, bearing, projectile
and charge. It would also take into account ship roll, speed
and coriolis effect for that target.
Gear ratios would make coefficient multipliers. They had variable
speed transmissions to make multipliers. Differentials made adders
and subtracters.

Hi
The Heath kit has 9 op-amps that are connected such that
they are all inverting. It is intended to primarily model
things that are linear systems but one can add such things
as diodes to make limiting functions. They do this for one
of the example programs to put a bouncing ball on an oscilloscope
screen. Other nonlinear functions can be added.
Although, one can model things with differentiators, these
are generally not very stable and tend to require more dynamic
range than integrators. Most linear systems can be described
as a differential equation. If one integrates the equation
a number of times, one can remove all the differentials and
be left with a number of integrals and initial constants.
These can be quickly scaled and represented by resistors
and capacitors. This modeling method can solve quite complex
problems. Things like aircraft controls to auto suspension
systems can be modeled this way. I had a friend describe
how it was used to make rail cars that wouldn't oscillate
at the same frequency as the spacing of the track joints,
over normal speed ranges. One can imagine what would happen
to the load and car if it were increasing the oscillation
on each track joint it crossed.
I currently have a EC-1 but a while back, I needed to solve
a control system problem with an oven. There were several
factors that effected the temperature and I needed to make
sure that the system could handle these changes without oscillating
or over shooting. I found an analog modeling program called
TutSim that I used to understand the system. This is just
like using a real analog computer except it used discrete
processing to simulate the analog world. There are potential
problems doing this and one needs to understand the possible
issues.
If you have a spice program, you can build up the equivalent
of a EC-1 in software and see how it works. It wasn't until
the late 80's someplace that digital computers became fast
enough to replace the simpler op-amps for solving these kinds
of problems. In many cases, the analog machines still have
better speed/accuracy tradeoffs.
My biggest complaint with the EC-1 is that they needed more
binding post for the common ( 0 Volts ).

Are you interested in magtape just for the media [has old National
Library
of Medicine stuff? (this would be at least another box)
==================================================
I have been advised that the above tapes are available, probably about
at least a dozen tapes for either the contents or for scratch. The cost
will be for shipping. They are in New York City, but may need to
first be sent to Buffalo.
If they are of interest, please advise and I will try and find out
what arrangements can be made.
I might also be looking to have 3 or 4 magtapes copied to a TK50
(or other suitable media) and might need some help in this regard.
They have RT-11 file labels if that is helpful information, so probably
RT-11 would be needed to make to copies. Eventually, I would like
to copy the contents to a CD.
Sincerely yours,
Jerome Fine

I agree that we could implement that. It becomes a little more
complicated when you try to generate the "group endorsed" prefixes and,
once you do, keeping those in the public eye so folks use them. I like
the idea, though, and think it would make the list easier to use.
We already have OT, FS and FA of course. What other prefixes could we
have? HW and SW? OS? PRG? HLP?

I don't think it's all that difficult to navigate although it is
different from an email interface and there are disadvantages inherent
in the greater flexibility. Once you get used to it, however, I think
it takes just as much time to remain "caught up."
On the other hand, you can eliminate topics you don't care about a lot
easier by simply tracking messages in the forums you are most
interested in. If you have no interest in Apple or Unix or the Off
Topic discussions you need never visit those boards. CCTalk will
always send you those messages.
The thing that I like the most about a threaded message board is that
you can view the entire discussion without any heavy manipulations. If
I want to do that with the mail list I have to either visit the
archives or use my mail program to sort on message header (assuming
that hasn't been changed mid-thread). As of right now I have nearly
29,000 CCTalk messages in my outlook CCTalk folder. Even with a P4 2.4
and 1GB of RAM resorting that list is slow.

The "new posts since my last visit" link is my favorite on bigger
boards. I hope that this new forum gets the kind of reception that
makes that feature useful. If enough people sign up and start using
the forums they'll hit "critical mass" which will make them that much
more useful.

I am way out here in Washington state. A long way from Michigan.
You can unload a C-10 here and I'm good for the cost plus.
Also I have been looking for a C-10 monitor pedestal if you see one.

Thanks, Lee! Either I never found that, or I thought it was just for

I picked up a board for the Apple II this last weekend, and am curious
if anyone knows anything about it? The silkscreening on the boards is
"APL BOARD", and besides an EPROM (Fairchild M88518H?) with "APL"
stamped on it, it has what appears to be a centronics printer cabled
attached.
> Activator, not the Activator 2.
That should read "Activator and the Activator 2."

Hi
I have no problem with sniping, other than that
I can't always be around at the last minute.
The only time I didn't like being sniped was the
first item I lost to this method. Once I understood
what was going on, I couldn't understand why bidders
would make incremental bids. I usually will post
a lower bid, early on. This way, other savy bidders
will check what I've previously bid on items and
they will either back out or, in those cases that
they just have to have an item, they will out bid
me. I think it tends to even out the play field.
I always look to see what other bidders have been doing.
I wouldn't mind having a combination of open and
sealed bits. I could then snipe without having
to wait till the last minute.

If it was OS X, then maybe (I know you can install other languages, I'm
just not sure if you can switch between them once they are installed),
but if it was previous to OS X, then no, not to the degree that you were
seeing. Rather it must have had a French version of the OS installed. If
you decide to buy it, let me know, I can get you a US-English copy of
whatever OS version was installed.
> 2./ Anybody make PC drivers for the great USB keyboard and mouse?
My iMac USB keyboard and mouse worked on Win2k by just plugging them in.
They also worked on my PlayStation 2 (well, at least the keyboard did, I
don't remember if I plugged the mouse in to it or not).
Of course, I lost the right click ability in Windows while using my iMac
puck mouse, but at least the mouse (and keyboard) worked without
additional drivers.

I need to remove several years of accumulated dust and
debris from the inside of an HP3000 Series 40. I will
remove the boards and vacuum the inside of the cabinet
(size of a washing machine), but was wondering what is
the best way to remove dust and dirt from the PC cards
in a way that will not damage them - mechanically or
electrically.
My default would be to clean with a shop vacuum, but I
was wondering if that might cause static damage to the
components on the board? Would a high pressure air
compressor be a better choice?
Thanks,
Lee Courtney

The 306/307s also have built in BCD decoders. I've been trying to find a
data sheet on the 311 so that I can see what the difference is between it
and the 306/307.

Hi
I've been looking at a pile of disk that I'd
collected over a period of years. Most are the
typical 10 hard sectored disk, formatted in the
same way as HDOS uses. In the pile, I found a
few that are marked "format 96". These have the
10 plus index holes but they don't seem to be
the normal format. When I attempt to read them,
I can only read the first sector. All of the rest
don't seem to read. Does anyone know what this
was all about?
Dwight
Hi Joe
This would explain why I can't read other tracks but
doesn't explain why I can only read the first sector of
track 0. When I get a chance, I'll put a scope to the
signals to see if it also has some changes in sector length
or something. The 96 does match to the 80 track drives
as 96 tpi. This does make sense.
I don't really know if it actually read the first sector
completely correct though. It may have read the data and
then failed the checksum, if the sector data was twice as
long, it would still read the first 256 bytes correctly.
Putting one scope channel on the sync output and the other
on the data should make it clearer what they are. Having
double length sectors would make sense with twice the
tracks. This would require less modifications to HDOS
in things like directories.
Dwight

>Just as a guess I'd say that they're 96 TPI 80 track disks instead of 40 track

pretty common on a lot of the early computers. I did that to my Sanyo and I had
a Kaypro that had the Advent Turbo ROM and 80 track drives installed.

I'm looking for either QBUS parts, or $5 + shipping for each of the
following.. Trying to clean out my room before I have to move in a few
months.
- SparcStation 20, 32MB ram, 1x50MHz proc, floppy, 2GB HDD.
I have 2 of these to get rid of.
- Macintosh IIfx with a pair of 16 channel A/D cards, and some sort
of interface software on the drive. It was originally a part of a
NMR system, and still has the software on it. Unfortunately, they
decided to crush the instrumentation that hooked up to the I/O cards
to do the NMR stuff. Has 8MB ram and (I think) a 120MB hdd.
- Macintosh Classic II. 80MB HDD, not sure on amount of ram.
- Macintosh Plus 1MB
- Macintosh Quadra 700, 16MB ram, 230MB HDD.
- Mac-plus style keyboards and mice (4pin RJ11 keyboard, DE9 mouse)
- PS/2 Model 70, with 6MB ram and an 80MB hard drive. I have at least two
to get rid of, but need to find where I stuffed the ram first...
- 2 Full-height 50pin centronics SCSI enclosures
- HP 9000 model 715/50, I think it has 32MB ram.
- IBM RS/6000 7011 Model 220 with 32MB ram, 400MB+ HDD, 2.88MB FDD,
Gt1x framebuffer
Now, what I'm looking for in trade:
+ Small-ish (can be lifted by 2 people) PERTEC or SCSI 9 track tape drive,
that is manual/autoloading. I don't really want one that's slot load,
I rather be able to see it spinning (and possibly manually load it). I
use to have one, but it died, and I'd like to get a 'new' one. This
would be worth a few things from the above, and I'd probably be willing
to pay some money for it.
+ QBUS PERTEC card.
+ QBUS RAM card for a PDP-11/23, 128kW or better.
+ RLV12
+ QBUS ethernet card that works with PDP-11 OS's.

Subject: I live in NYC and have no space for my old Mac...
Hi,
My name is Stacy Yoshioka and I have a very old Mac computer, monitor and printer that I no longer have space for. I have purchased a PC laptop about a year ago and since I live in a cramped NYC apartment I cannot store it any longer and have finally transfered all of the old info to a PC disk. Anyway, it is a Performa 6360 and the printer is a Style Writer II. The entire system still works and I have the manuals and backup software. I also installed about 100 mb of extra memory when I got it. If any of your organizations could use this machine please let me know. I saved so much money to buy it when I was in college that I can't see just throwing it away. I do not have a car in the city so if any of your organizations pick them up or are easy to get to please let me know as well.
Thank You,
Stacy Yoshioka

I'd like this. I've got a Dilog DQ130 Qbus card (pertec controller AFAIK)
and a Texas Instruments TM10010 Qbus RAM card
(128k x 18 bit I thnk), but I doubt it's worth shipping the RS/6000 to
Australia :(
