the infamous grooved disk? is there anything wrong with that design? looks
fairly clever and reliable. i havent seen any wear problems with the 20+ apple
disk drives i have. the only minor issue is adjusting the head stop for which
all you have to do is sight a little dot on the grooved disk (apple calls it a
cam) with the little metal cam follower and make adjustments as needed.

Picked this thing up at Wacky Willy's in Portland, OR for $5 with a floppy
drive(actually two 5.25" drives in a case with a PS). Not quite sure what
to think of it. It says ATR8000 SWP Microcomputer Products on the front,
lighted power switch on front, and on the back we have two 13-pin Molex
connectors marked Peripheral Out and Computer In, and three edge-connectors
marked RS-232, Printer and Floppy Drive. Inside it says Software
Publisher's ATR8000, and has a Z80 CPU, a WDC floppy IC and a VERY small
amount of RAM... They assumed it was an Atari of some sort, as they
recently got an 800 and 800XL. Does anyone have any idea what the ATR 8000
is?
BTW, if you need some Univac disk packs(don't remember the numbers on it)
they have two at WW's. Kinda expensive, they say they sell the platters
seperatly to artists @$10 each. With 4 or 5 platters in each pack, you
either need to shell out almost $50 or be good at convincing them that it's
not worth that much(and it's not easy, I've tried before). BTW, it's at the
Vaughn St. location, at the end of the Fremont bridge(US30 exit, then the
Vaughn St exit from the exit ramp...).

I maintain my stance that 'microprocessor' is a term used by the
public and media to refer to a series of technical developments, that
are not well considered before calling them microprocessors. In
short, there is no way to define a microprocessor in the technical
sense. TI's 1979 book Understanding Microprocessors defines it as:
A digital integrated unit (or a set of IC's) that contains the
digital functions necessary to be a CPU. It "processes" information
and controls and keeps the system working in harmony as it responds to
the step by step program that the CPU follows.
Nice and circular :)

That is a (iirc) CP/M(?) box for an atari 800. I believe it plugs into the
800 (or other 8-bit atari) and the atari is the terminal for the CP/M
Machine. Pretty amazing device. (Pretty amazing that I recognized the
name! 8^)

Actually a fairly powerful acid is the citric acid in lemons and limes
that people can and do eat/drink. Most pharmaceuticals use citric,
hydrocloric and some preps even nitric acid to get a the required PH.
This is really way off track for cleaning boards unless they have been hit
with a strong alkli (leaking nicads!), in which case a good dousing with
vinegar (acetic acid) or lemon juice (citric acid) will neutralize that.
Anyhow the PH and total acidity of a dishwasher unless useing something
strange is fairly mild. Electrolytic corrosion (usually from ionic
solutions and dissimilar metals) is prevented by quickly drying the board
either with mild heat or forced air. Unless your water is bad (unsafe
to drink) it is likely fine for washing a board.
I've done this to 10-15 qbus cards, a Micronta DVM, and several s100 cards
with the expected result, clean. I do it on boards I'll have to work on
as it's less messy and in one case it cleared a short!
FYI: I used to service marine radios when I lived on LI,NY and the
procedure for dunked electronics was toss it in a barrel of clean water
ASAP to get the salt out. This is repeated with several barrels of clean
water to get all of the salt. Then the equipment is than opended, cleaned
and repaired as needed (speakers, microphones, buzzers, enclosed coils).
Generally speaking potable water is ok, mud worse (abrasive), salt
is real nasty.

Um, I don't care what anybody says, but that disk drive does NOT look like
anything similar to an Apple Disk II.
BTW: I used to have a Disk II, and the heads were positioned by a stepper
motor, and didn't have any "spiral-grooved disc" anywhere in the entire
unit.

But since most working implementations of an 8088 (the only one I
have the databook for) require additional ICs, I'm wondering if it
could truly be called a single-chip CPU. I mean, this thing needs
chips for the clock line (8284, this says). It needs more chips
for accessing RAM, and it needs RAM. Why do you say it's single chip?
I think the only way to determine if it's a microprocessor is to
look in the company's literature. If they call it an arithmetic logic
unit, it's not a microprocessor.

The dry cycle is ok if the temperature is under 180f, too hot and it
can over heat parts. I prefer the oven at 160-180f as it's drier
and a bit faster. A blast of compressed air is also good for getting
water out from under parts to hasten drying.

If all goes well, my employer, The Press of Atlantic City, will be selling off
an almost unlimited stock of working DEC Rainbows in 1st Q '99 (and, boy will
I be glad to get something "modern" like a 486 on my desk.)
Anyway, in addition to being collectors items in their own right, they have
the same basic mechanical and electrical components as the DECMates. Word I'm
getting is they'll go for cheap to anyone looking to keep them alive or in
need of parts, at or just over scrap value.
Also up for grabs will be at least one major PDP-11 system.
I'll keep the list posted with the latest news including when and how to order
your own PC-Clone and DECMate repair kit.

I've had several dozen Disk II's, and they all had stepper motors with
spiral grooved disks. Many, many drives were based around the SA390
and 400 mechanics, and some of them look quite dissimilar from the outside
despite the fact that their internal mechanics are very similar.
Kai - you mention on your web page that when you turn the machine on you
go into a boot ROM monitor. What are the prompts like? Any copyright
notices? Menus? Any "obvious" commands?
Tim.
Since I shut down the at home/on site business here and went to work as
an ISS/CSS at a local corporation I need to do some cleaning out of
excess here. I have many, many machines from 8088 through 80386DX that I
can make a reasonable deal with someone on (not as cheap as an unknown
condition thrift shop sale though) for mostly main units (you add the KB
and monitor in may cases) but I have a few setups that are complete such
as a 5150 PC that does have a 5151 monitor and original keyboard.
PS/2's out the bung hole, Dells and AT&T's, etc. Many will have to be
dug through when someone inquires about the condition and what it
includes but 99% are in great condition other than minor wear and tear.
I'm always looking for odds and ends for my machines here such as
drives, cards, modems, etc as well as electronics test equipment for my
bench. If you have something to trade rather than cash (which is my
favorite, as is many other's) then let me know and we can go from there.
Please email me direct so this isn't a problem with the list. I hate
putting this on here but the people on this list seem to appreciate good
sturdy hardware and see the actual value and use for it rather than
seeing a pile of scrap with gold retrieval possibilities.

Just gotta be sure you pull the board before the rinse cycle :-). Then
it's usually best to rinse it with distilled water.

I see one about every two years. I have 3, 2 of which are in boxes.
And I've managed to collect all of the regular cartridges, except
for #26, in the boxes with instructions.
#19 is the hardest to find.
http://www.best.com/~dcoward/museum/mvfair.htm
There was a second system (System II) that I believe was
produced by the company that bought the rights to Channel F from
Fairchild. The big differences in the two systems was that the
original had a dark plexiglas cover over the controller storage
compartment and the controllers were hard wired into the unit.
It was the first home video game system to use programmed
cartridges, but I think the cool thing about the Channel F was
it 4 axis controller.

Back to the original topic some. History. MS was not the only game
in town. DRI, later Novell, now Caldara offered CPM86 and it decendants
such as CCPM and DRDOS until MS crushed them. Caldara is still at it
with Opendos (DRdos decendant).

I'm no fan of MS but I run a ton of CADD, FPGA and cross assemblers
unavailable for Linux or freeBSD. The system that I must run it on
is MSdos6.22/WIN3.1 that generally has an up time of months between
reboots. The last down time was for a fan replacement. I've never run
w95, but I've seen systems that can achieve that as well. My other half
has a laptop for work that seems to be solid enough. None of the
MS OSs are great products, they work ok though and when the system is
configured with stable hardware and software. I've also found that
linix or freeBSD tends to beat the daylights out of hardware and find
even minor problems that seem to get by under MSdos/win but cause it
to crash intermittently. Most of the complaints I've heard of MS
dos/winders can be leveled at Linux or other unice as well. My pet
peave is that most of the PC unice are limited about what hardware
they run on and like win95 also will not be happy with a minimal 8meg
of ram.
Now what has this to do with old hardware. Unix has been around for
some time, some 25-30 years. It's still not the generalized platform
for applications software. I find that good low cost CADD tools are
non-existant and most require Xwinders which is a memory hog and yet
another potentially cranky item. So until I can find a good CADD,
schematic capture, PCB routing, XAble and Xilinx FPGA package for PC
unice for under a few hundred $$$ MS wins. That defined the market.

This is bogus. 1983 was not the end of the line for 8bitters yet. The
8088 was still gathering steam but far from a full head. the 8bit world
would have another two years or so to peak. The Franklin ACE1200 in the
may'83 Microsystems is only one example.
The PC may have launched in 81... but it wasn't the defacto force quite
yet in 1983.. or 86. If anything I'd call that the processor wars eara
with 80186, 80286, 64180, 65816, 16032, 68000 to name a few all jockying
for the next better runner. While that was going on new z80 and 6502
systems were emerging that were smaller, cheaper, faster to capitalize
on the existing and still growing software base.

Now, thats what I call early.
Of course you are right. I did only think back to the 60's

programmed).

Micro-SCI made a line of Apple II and III compatable disk drives in the early
80s. I bet they made an Apple clone wannabee. Try apple dos 3.2 or 3.2. You
could have gotten a copy of that too in my whse this weekend.
Micro-SCI was a division of Standum Controlls, Inc. in Santa Anna, CA. This
came out of their ad in a March, 1983 Byte.
Hi;
I have just listed on ebay a group of Sams Computerfacts that I have had some
interest in from people on the classic computer list.
They are for:
Computers - Osborne OCC1 & OCC1A, TRS-80 Models 3 and 4, Epson QX-10, Franklin
Ace 1000, Atari 800XL, IBM PC & AT, AT&T 6300, Leading Edge D
Monitors - IBM 5151 and 5153, Amdek Color-I and the Video-300
Printers - Okidata Microlines 82A and 92, Apple A90303, NEC PC-8023A-N, NEC
PC-8025A, IBM 5152-002, Epsons MX-80 IIIF/T, FX-80, FX-100, MX-100, RX-80,
FX-286e, Star Geminis 10X and 15X
These can be searched for by the keyword "Computerfact" (Singular context
please).
I also listed a factory Toshiba T 1100 plus laptop maintenance Manual.
All of these are under Computer/hardware/books.
Paxton
p.S. Please direct questions toi Whoagiii(a)aol.com.
Damn, you're right, that was the same as the early SA400's. This one isn't
built nearly as solid, though, and the clamp mechanism is driven by
strings(!) that run over pulleys just like an old radio tuner mechanism.

Well... while I am not familiar with the 'HAVAC', to find a more common
use of the "spiral grooved disc" for head positioning, just look in any
Apple II disk drive! (the early ones, not the 'DuoDiscs')
That was the standard early Shugart 5.25 inch disk positioner mechanism.

The IBM 4224 is a 200 to 400 CPS dot matrix printer (usually 18 pin) for use
on IBM networks. It sounds like you have the Twinax interface, about 1" in
diameter, screw connector, with two pin holes. It is not usable on anything
but a twinax network. I bellieve that IBM made 3 versions of varieing speeds
in two interfaces. The second interface is a BNC Coax for the 3270 systems.
While the networks are over 10 yrs old I doubt the printer is.

This weekend I picked up this wacky little 6502 computer called the Microsci
HAVAC. Has anyone else ever seen one of these, or better yet, does anyone
have a boot disk for it?
The HAVAC has the weirdest floppy drive I've ever seen. It has a
center-mounted clamp lever, and the head positioning is done via a
spiral-grooved disc!
The machine is about 16" deep, 10" wide, 8" tall, with the floppy drive in
the center front (there is no door on the drive, just a slot and the funny
lever -- no eject mechanism either, just pull the disc out manually). There
is a small external keyboard about 10" by 13", no numeric pad, connects via
a D-sub connector. On the back of the system unit, there are serial,
"printer" (parallel?), 2nd floppy, and RCA video output connectors.
I fired it up, and it displayed a HAVAC logo, ROM version 1.3, then the
expected "no disk" error. I examined the system board, which is dated 1983,
and has a 6502 CPU. There is no info anywhere on the net about this
machine, that I can find.
Any info appreciated,
thanks

No, those running MS software are doing so mostly because MS was

you're the only one... also not hard to be 'worst'...
Personally, I avoid MS-anything like the plague... I have a linux

W95, I'm lucking if I *don't* have to reboot several times a day
either because the system has simply crashed, or wedged itself...

I will admit up front that I don't know everything, and I am not an EE
(dropped out of community college) but it seems to me that Intel hadn't won
anything until ~81 when IBM came out with their PC. Until then, the Z80
and 6502 were as dominant (if not more so) than the 8080/8085?
In fact, I'll go so far as to suggest that perhaps if IBM had gone with,
say, the z8000, Intel would not be anywhere near as big as it is?
It seems to me that what really got the "cheap computer revolution" going
was the Z80 (CP/M, TRS-80, etc.) and the 6502 (Atari, Commodore, Apple II).
Because no matter what the tech-heads are doing in their garages, nothing
is a revolution until you can buy it at Sears.
There is a similar situation with digital recording -- it's been around and
available for eons, but mostly was only available to those with lots of $$$
(big studios/record companies) or tech-heads. Now, with the
soundblaster/CD-R combo and some software (which, if it isn't available as
shareware, I would be extremely surprised!) anyone can cut a full-digital
(DDD) CD at home.

I think that the amount of marketing necessary is related to the
quality and value of the product itself. After all, if a computer
is reeealy good, only a simple demonstration is necessary and it will
be bought. If the product is nothing new, then $150m will be spent
making it successfull.

I have seen several who think IBM is a failure. Once, I was at a
computer store with another person, getting a computer repaired.
THe other person asked the tech 'So, do you think Apple will survive?'
The answer was quick: 'Sure, IBM survived, didn't it?' I asked her
what she meant. She said, 'Well, their entire PS/2 line was killed
off'. For one thing, the PS/2 shows that with great marketing and
technology, a product can still fail. Secondly, it would appear that
in most people's minds, everything before the PC is a haze.

Well, IBM really had very little competition. DEC and Data General
were quite successful too. But, since IBM was already around making
typewriters and card punchers, it was already firmly established in
the market. Did NCR ever venture into mainframes and minis, BTW? I
have seen a nicely designed AT clone of theirs.

These set the starting "logical unit number" for board, as a binary number
(W12=LSB, W17+MSB). If you have multiple RQDXn boards, you'd typcally set
the second card to start with LUN 4, the third with LUN 8, etc. Jumper out
= 0, jumper in = 1.
> W23 -- I think this is for what kind of cabinet that the card is

No, it controls the HEADSEL 3 and REDUCWRTI signals. W23 has 4 posts
numbeerd 1..4. Factory setting is 1-2 jumpered on early firmware, 1-2 and
3-4 for version 2 firmware (ROMs 23-243E5/23-244E5) or later.
Alternatively, you can jumper 2-3, which has the effect of connecting
HEADSEL 3 to pin 9 of J1, and REDUCWRTI to pin 22. That allows you to use
hard drives with more than 8 heads.

Fishpaper as some call it. It's a thick stiff paper put ther to prevent

Guys:
Are there any of you out there looking for these beasts?
I know somebody who's got a 5120 and a 5126.
He's asking $50 each (too high in my opinion), but the
price ought to be negotiable.
I know he also has at least one power brick,
and an NOS portable battery charger (M0275).
Send me personal e-mail if there is any interest.

The CADC itself was of little direct impact as we never saw it. The

apply that to the next product. Also, since Ray Holt didn't do it alone
there wer a slew of people that also gained experience they could apply

easier to create the next product and also possible to do it less

Their advert in November 1971 electronic news. A quote:
A micro-programable computer on a chip!
Intel Introduced an integreated CPU complete with a 4-but
parallel adder, sixteen 4-bit registers, an accumulator
and a push down stack on one chip. It is one of a family
of four new ICs which comprize the MCS-4 Micro
computer system - the first system to bring you the
power and flexibility of a dedicate general-purpose
computer at low cost in as few as two dual in-line
packages.
Seems they were aimed squarely at the low cost market. They would
introduce the 8008 and 8080 in the same ways.

Likely for the same reson I used the 8008 the first time. Intel was
visible and advertized. When I helped pick the 8008 in late '72 I could
point to a working board (MCS-8) and docs to help us newbies. We used
what we knew about and at 200$US each they weren't cheap at all but it
was better than 200 pieces of TTL that had to be wired and tested.
So the Mark-8 Etal had the precedence of visible advertizing, Docs and
availability.
An aside , the docs part was not lost on moto! You could get the 6800
cheap enough and for 25$ more you could get a thick volume of hardware
and software knowlege that made using it easy.
< What I'm trying to say is that this revolution would have happened with

What is missed and not mentioned is the small details. INTEL created the
4004 becuase they didn't want another fixed function calculator chip for
only one vendor. This ment they could mass make it and sell to everyone
with higher profit. The 4004 was significant as it had a hardware return
address stack. There are things there that did seperate the micro
computers that would result from the minicomputers that were before.

Some perspective... in mil spec design, construction and testing made
it likely several thousand $$$. Even if it were 10k$ per it was cheap
compared to available processors of the time and none fit in that form
factor.
Also the 4004 was *relatively* cheap but the amortized development cost
were still significant and have to be include to be fair.

I'd say there is some reality there. The big bangs were those that would
hit the media and cause ripples down the line.
Using that line of thought... the CPU chip was not the big bang but the
catalyst for the explosion. IE: Altair was not significant due to the
8080 but that it was first of class and more importantly COPIED. Name
one other machine/bus before ALTAIR that would be copied widely and
competitively within one year of introduction!?!
I will add that I doubt Intel saw it as a serious opportunity to sell
chips until after the Pop'tronics cover hit the stands. Reason it would
be little while before the hobby (we were called that) market would be
taken seriously and semiconductor vendors would see the potential of the
early edge of the personal computer/ small desktop computer industry.
That got DEC, IBM and DGs attention though none were sure of what to make
of it. The fact of it was by 1978 there was no question that there wer
more microcomputers (or various types) than all of IBM, DEC and DGs output
to date!
It was the Volkswagons of the computer industry. Tin Lizzie, Ha!

New computers announced at the 1983 CES:
Vaporware? Please respond if you KNOW any of these exist for SURE.
- Panasonic JR-200 (I think this may exist)
- Sanyo PCH20/PHC25 (Z80, 4K/16K, $99/$199)
- STM Pied Piper (CP/M portable, 64K, $1295)
- TI 99/2 (Supposedly $100, including 4.2K RAM)
- TI CC-40 (Compact Computer 40, laptop like Epson HX-20, 4 AA cells, 31
character LCD display, $249)
- Unisonic Futura 8300 (Z80, 2K, Sinclair BASIC, $90)
- Video Technology VZ200 (Z80, 4K, MS BASIC, $99)
Not Vaporware
- Jupiter Ace
- Mattel Aquarius
- Spectravideo SV-318
- Timex Sinclair 2000
By the way, has anyone actually seen an TI 99/4 (not 4a)?
