Yes patent issues and different drive methods. The decatron or Numatrons

Man things over on eBay are getting hairy. A Sol-20 and IMSAI 8080
recently went for over $600 ea. And the Sol-20 may not have sold
because the seller's "reserve price" was not even met... Currently
there is a MITS Altair 680 at $1,825 and an Apple Lisa at $500, both
with over 2 days to go until the deadline. Oh well, it's back to the
old thrift and scrounge circuit for me.

OK, help me brainstorm arguments to persuade companies to release
obsolete information. Certainly pointy-haired managers (does the
cartoon "Dilbert" cross the pond?) will opt for the simple safe
solution of "don't let anything out of the office, or out of our
control". And there's the question of money to be made. As soon
as someone seems interested in old technology, they'll believe
there's still some money to be made. Then there's the question
of the cost and trouble of drafting or approving any legal document
to make the transaction official. Why spend money on giving away
products?

I have heard tell (from a very reliable source) of a version of Unix
written for the Radio Shack Model 100 (8085, 32K max). (And no, it's not
available, and yes, he's tried to get the company that did it to release it.)
I thought someone had said that CP/M was based on Unix? Or was that one
of the PDP opsys?

Hi all,
Anyone interested in a complete set of Digital Ultrix manuals
dating from 1990/1991?
I am assuming they are complete, given a lot of them are
still shrinkwrapped.
Email me with your physical address with a Fedex or UPS

I have six VAX computers and NONE have floppies. Why, becuase even
1.44mb floppies make sense in that environment. Since they have tapes
and are networked together floppy is of little use.
With the size of applications and all a writeable CDrom or a ZIP disk
makes more sense than floppy.
Further, I'm working on a z280 design and am seriously considering
no floppy. Why? Eats power and space for intermittent use at best.
I'd rather use a utility I wrote years ago to transfer files via
serial port (back when no two machines had the same format or size
floppy). I even intend to put the whole OS and then some in EEprom
as it's cheaper and faster that floppy or hard disk.

Hi. It just occured to me: Apple is known (with the ][) to have pioneered
low cost floppy drives. They're the ones that made it a good alternitive to
tape. But still, I agree, floppies arn't really an important part today,
other than a remembrance of the past. (Has anyone seen those "Download

The explanations of physics is based on the core of mathmatics.
That's one way to look at it. Consider it from the perspective of a
mathmatics view. Signal goes in FNC(x) is performed on it and signal
comes out. FNC(x) can be performed using a DSP or analog circuits
>from the outside of the black box dos it make much difference how?
Computing is a process of calculation. Analogue functions perform
calculation vastly different than the digital forms it does not negate
the calculation performed. If this wasn't true digial signal processing
would not be possible.
I still have the Popular Electronics article that simulates the bounce of
a ball in analogue form using opamps while displaying it graphically on a
scope. Yes the ball would even flatten at the bottom of the bounce.
Years later I would write a program to do the same, the mathmatics were
unchanged as where the physics. The analogue form was faster at showing
how small changes had an effect, it could be real time. The digital form
allowed me to express those as floatingpoint numbers. Even on a PDP11 at
the time, it would never approach real time.

Apple machines already do now.

Quite clearly, this machine is not designed as a Corporate machine. One
look at the physical design alone is enough to establish that this is for
home use. Apple continues to sell quite traditionally designed machines
for THAT market segment.

And now that we've all hashed and re-hashed the merits of this day-old
computer, can we return to discussing our 10-year old classics? Let's all
agree to meet and re-evaluate the iMac in 2008.
<Non electronic digital _computers_ are a lot rarer. If we decide that a
<computer has to have a sequence of operations and some kind of
<conditional branching, I can't think of any at the moment. Mechanical
<sequencers, based normally on camshafts are common, of course.
You kidding, air logic has been around for years and frequently used in
atmospheres or other considerations that would prohibit using electronic
or electically power controls. The basic elements such as switchs valves
and oneshots all exist and can be combined into digital functions. I know
I demonstrated a system where several inputs (switches) had to be true
before a sequenced action using two bistable elements and a oneshot. It's
not fast but fun to watch!
<Are you thinking of 'Digital circuits are built from analogue parts' ?
Not a valid concept. both OR and AND gates can be done using totally
non amplifying devices (diodes).
It was Vonda that postulated that digital was analogue with a precision
of two states, true and false. The realm of analogue is one of infinite
precision but possibly of limited accuracy. The digital realm is one of
limited precision and absolute accuracy.
<As a practical point for this list, if just about all (analogue) circuits
<are analogue computers, then they are on-topic here :-). No I don't
As a final thought, analogue circuits often perform complex functions.
This very aspect and the realization that precision and accuracy are
very differnt commodities are why some fuction are easy to do using an
analogue approach and can be very difficult to do digitally.

I can imagine a floppy disk stealing his college thesis. Pretty
likely, actually. AFAIK, though, NO NeXT has shipped with floppies,
but rather with MOs, which are pretty annoying because of the many
formats and price per disk.
Actually, if I were to design a computer, I would consider not
including a floppy drive, or at least making it so that it doesn't
depend on it.

can contact you about them. He is getting working units for the cost of

Nope.
Kind of off the classic subject but...
USB is for sound, keyboards, pointing devices, joysticks, single-user
printers, and low-bandwidth video such as webcam/lowres
videoconferencing/frame capture. USB is a low-speed bus that is already
overwhelmed with all of these duties without dropping a very high bandwidth
storage device on there as well. The last thing you want is for your mouse
to get choppy when you print, for example. The "high speed" version of USB
is only 1.5MBps and Dolby Digital AC-3 DVD audio can take half of that
alone. We are strongly evangelizing against anyone doing fast storage
devices for USB.
IEEE1394/Firewire is the connection of choice for full motion video/editing,
storage devices, workgroup printers, etc.

OK.. this is very quick, but basically, I want to outline the following
points for making a way for old, no longer profitable hardware/software to
make it available:
Reasons To Change
1) Public relations. People who think that you're giving away info on
products that your company made will have a profound effect on anyone
involved.
2) No longer responsible for the information. You don't have to archive old
data anymore, meaning that you can make information lean and clean. Support
for old products can come from those who now hold the information.
3) Recieve credit for work. You (the company giving information) will get
credit for your work, meaning that if someone thinks that Product A Rev. 1.x
has innovation, then Product B 8.x will, too. Also, it means that you
significantly increase your user base without costly advertising/marketing
campaigns.
Now, here's what I propose needs to happen to get this done:
1) Liscense agreement. This would be similiar to the GPL (in the fact that
it's free, but does not bar anyone from profiting by information.)
2) Central orginazation. Something like GNU, but less proffesional. It
would contain all archives collected, as well as user-made enhancements,
notes or other docs. (For example: Getting a ST 251 to work under
Linux/Windows) Then for support, tech. support reps. could reffer ceretain
products to the orginiaztion and not waste any more time. This would prove
to save companies time and money, especially if it saves training.
3) Petition would need to be made of lots of people (Founding members)
willing to support this idea, weather through time, money, or just a name
giving support.
For the liscense agreement, we need to be as flexible as possible to get
as much information as possible. So we'd have levels, where any information
could be used for commercial purposes (building new drives based on
information), where it could be used for referance (for instance fixing a
drive), or for "small" commercial purposes. (For example, Fredrick's XT
Part Shop could build new Seagate MFM drives/re-sell modified copies of
PC-DOS 1.x, whereas Maxtor couldn't.)
So, this is just a basic list, and I want it to get improved, then when
we're sure we know what we want, finilize it, legalize it, put it on the
web, and propose to hardware/software manufactuers.
Just my 0.02 (with interests, no doubt.)
