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 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.

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.

Quite clearly, this machine is not designed as a Corporate machine. One

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.

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.)

CP/M was based on OS/8 and RT-11, it is very un-unix. DEC Ultrix-11 and
Ultrix-32 are both unix based on BSD versions.

I disagree. Apple, at least to me, represents that innovation can live in
today's computer industry, and that being different makes you ahead, not
behind of the crowd. (And yes, I thought that BEFORE Apple's current
marketing campaign.) Looks cool, but I want more information, and, as most
people go, they'll need reasons to want a $1.3K over a $600-$800 PC.

It's a QBus controller for SMD drives. It will support two physical
drives, making them emulate two (or more, if necessary) logical DEC drives.
We need to know the suffix (SC03/A, SC03/B, SC03/C) as there are at least
three versions, emulating different drives. I have an SC03 which emulates
RM03s, but there's an MSCP version as well. I've got the manual for this
one, too.

QBus communications controller of some sort. I don't know the details on
this one, though.

I think so; I expect it's the Unibus equivalent of my QBus TC02. I've got

Exactly. I also expect if the technical support is not via phone (IE from
e-mail, web based, etc.) to get a timely answer. With my old soundcard, it
was 3 months, by which time I'd gotten so fed up I'd figured it out anyway.
Now I use a real Sound Blaster AWE 64. I like the cool sound.

I was at the scrap yard yesterday, picking up some aluminum blocks to
play with on my new CNC milling machine, and decided to take a stroll
out where they occasionally dump old mainframe parts. It's just this
huge mud lot about 2 blocks square, with big mounds of twisted metal,
wire, cable, crushed cars, and all kinds of other junk, with a bunch
of bits of electronics thrown in more or less at random. I wasn't in
the mood for a lot of climbing, so I just poked around the edges. I
found a board about 18" square sitting on top of a barrel. When I
picked it up, it was *way* too heavy for the size. Flipped it over
and saw another, smaller board screwed to the bottom. It was marked
"DataRAM". I thought "Oh no - surely not. It can't be core memory!
But it's so *heavy*! What is it?" I took it along. I also found an
old controller module of some kind with an RCA 1802 and support chips
on it; now maybe I can finally build a real Elf. Anyway, they sell
everything by the pound, and the two pieces cost me about $2. Brought
it home, removed all the screws around the edge, pulled off the
smaller board, and guess what? Acres of core! Tiny little ones, too
- I haven't seen that much core, but the other small piece I have has
cores with a center hole about the size of a pencil lead. These were
so small they looked like grains of sand, or salt. Had to use a 12x
magnifier to see them clearly. By my count, there are about 100 per
inch in both directions, and it's about 8"x10", with a few gaps here
and there, so this gives... ummm... (square root of 7, carry the 9...)
uh... something under 800k-bits or so? Does this sound right?
Anyway, I was pretty pumped. I may go back and do some serious
climbing and burrowing this weekend...

<be interested. Will they be SYSGEN-able? That's one thing I miss in
<the RT-11 image that came with the emulator. But I'm not going to look
<a gift horse in the mouth.
Rt-11 does not require sysgening like RSX or RSTS So just the binaries of
the standard monitors (SJ, FB, XM and BJ) and the standard drivers
is all that's needed to use it effectively. RT-11 really only requires
the disk used to boot to have the boot blocks installed (copy/boot)
and it will run on all PDP11s and most all disks. Known disks supported
in v5 were the all the RXnn drives regardless of controller
(rx01/2/3/50/33) all the RD drives, RK drives, pro350(DW/DZ), TU58
tape(bootable and useable as system device) and most of the mag tapes.
V5 includes a ramdisk called VM that can even be booted assuming you have
plenty of ram. An 11/23 with 1meg ram running RT11FB will have plenty of
space in VM (about 1900 blocks) for a useful system. I know as I run it
on 11/03, 11/23, 11/73 using RL02, RD5x, RX50, RX33, rx02, TU58 and VM:.
A useable system fits on any 256k(497 blocks) dual device (tu58 or RX01).
A rx50(800blocks) system is fairly roomy. Any hard disk is fast and
plenty of room even small 5meg(10,000 blocks) RD50s. The full V5 kit
minus .mac files fits in about 4-5000 blocks. Removing the unused drivers
and other misc files really cuts this down. A block is 512bytes.
I didn't mention but RT-11 is NOT a memory hog and even a PDP-11 with
16kw can run a useful system. Being a low fat OS it is also very fast
permitting even slow PDP-11 processors a chance to look good. It's
basic commands look just like PC dos.
An emulated V4 system should be useable to do PDP-11 program development
and run standard monitors. the minimum hardware needed is any PDP11
(even the falcon card!) 16kw ram, mass storage (floppy or hard disk)
and at least one DL serial line (console). The boot an even be toggled
by hand.

I think you may be confusing my remark with Tony's. I remarked that
"all circuits are amplifiers" meaning that the general circuit can be
modelled as taking an input, applying some sort of gain, and producing
an output. A gross oversimplification, but I wasn't talking about the
active/passive issue (gain>1 => active, etc.) Tony made a slightly
different remark, "Digital circuits are built with analogue parts".
Unlike mine, this is not an oversimplification, it is absolutely true.
And has nothing to do with amplifiers. You can build a digital circuit
element with diodes; they are analogue parts, and they don't amplify.
Clear now?

I never (intensionally) disputed this!

I couldn't quite read your diagram, I'm afraid. Was it series capacitor
followed by shunt diode? Looks like it refers the input to the lowest
value it (the input) ever takes, rather than to ground or a fixed
reference.

Roughly what I thought. I wasn't sure whether people would class it as
a computer, but I think it is no less of one than a 4-function pocket
calculator.

Is there a limit to how big a RSTS filesystem can be?
I'm told 8.0-07 doesn't support RA92s. But the fact that INIT knows what
it is tells me otherwise. All I have to do is find the CMP instruction
stopping me from formatting this disk and off we go. The question is,
is the RSTS filesystem used in 8.0-07 able to handle a drive this size?
Is there some filesystem-induced wall I'm about to walk into?
-------
Of course everything I've dragged home in the last few months simply pales
in comparison to the prototype Apple //c I brought home today.
I was on my way back to work in the early afternoon and was trying to
decide if I should stop at my favorite thrift store on the way which would
put me in traffic, or if I should cut across the hills to get back
quicker. I thought to myself that there may just be something at the
thrift store that would make the trip worth it, so the thoughts of finding
something cool won over my need to get back to the office. This is one
case where I'm glad I let my irrational urges get the best of me.
The first thing I saw when I got to the electronics section was an Apple
//c, and I thought to myself, "Hmmm...do I want another //c?" (since I
have like 3 already). But when I picked it up I noticed something strange
about it. The case was smooth instead of having the normal texture. I
flipped it over and noticed there was a small green sticker on the bottom
instead of the normal grey one with the Apple //c wording and part
numbers, etc. The sticker read "Apple Computer Inc., PCSD MFG, 3087 North
First Street, San Jose, CA 95134" then the words "Prototype" and "Test
Equipment" with check boxes next to each. "Prototype" was checked off.
Of course phrases like "holy shit" went through my head. The label also
had a serial number of "P1160" and at the bottom was "WARNING: PROPRIETARY
PRODUCT". Now this was too cool for words to describe (<--- isn't that
deliciously nerdy?)
When I got home I opened it up along with a regular production //c and
started comparing the motherboards of the two. There were several minor
differences. Some silkscreen lettering was different and there were a
couple minor component changes, but nothing significant and for the most
part the board layout was identical.
I pulled out the power supply on the prototype and the production model
which unveiled the following:
Prototype Production
--------- ----------
TERI MAIN LOGIC MAIN LOGIC
820-0115-0 820-0115-C
(c) 1983 APPLE COMPUTER
APPLE COMPUTER (c) 1983
Was "TERI" the codename for the Apple //c?
A couple other interesting differences: on the prototype, there was a
small board with the labeling "Apple Computer Network SKA156-00" in the
place near the serial port where on the production model is a simple
transistor pack. The "network" board simply has transistors on it. Also,
at location C19 on the proto is a 74LS161 whereas on the production there
is a 1.8432 Mhz crystal. On the proto, the CHAR GEN EPROM is socketed and
the system ROM is an EPROM with a sticker which has "v1.0 5/19 5F85"
written on it. Lastly, for the motherboard product number (all Apple
components have a product number in the form of xxx-xxxx-x) the proto had
6xx-xxxx-whereas the production has 612-0128-E.
Oh yeah, the proto had a spider living in the connector of the power
supply. Spiders find the stupidest places to spin their web. What the
hell did he expect to come crawling through there!? I was just going to
flick him off into the room but if my wife found him a couple days from
now she would've fainted, so I did away with the poor little sucker.
R.I.P.
Here's where you envious types shoot yourself: I paid $2.98 for it.
:)
I've found some of the best stuff in thrift stores, but this beats all.
It will be proudly displayed right next to my prototype Apple //gs at the
next Vintage Computer Festival.
