I'm looking for a Seattle Computer Products CPU Support card. It's an S-100 card with various mixed functions on it. If anyone has one or knows where I can find one, please let me know.

I've finally gotten round to putting a page up with the pictures that I
shot at the Moffitt Field Historical Computer Collection "Visible Storage"
facility during VCF II, but have spaced a bit on the identities of some of
the artifacts.
The page is not quite ready for public consumption yet, as it is still
missing various titles and it should be a bit better organized... But, if
anyone would like to take a look, and perhaps assist with identifying the
units without titles, you can access the page at:
http://www.rdrop.com/~jimw/jcgm-mfhcc.html
Until I get this page 'finished', there won't be a link from the regular
'Computer Garage' pages, so you will need to use the direct URL above.
Thanks in advance for any assistance you can provide!

Some of the people who clean keyboards for a living use Ultrasonic cleaners.
Years ago I got a sample of a cleaner that you mixed with water that was
formulated for ultrasonic keyboard cleaning. You also need an Ultrasonic
cleaner that you can submerge a keyboard in. Unfortunately I don't have the
name of the company anymore.

I collect old radios, and I can definitely say differently. Just try
plugging in a metal-cabinet radio with a few bad tubes, turning it on, and
touching the case. Also, get out of the way when a shelf collapses with a
52-pound short-wave receiver on it. Other than that, you're probably right.

Well, even though I haven't tried it yet, it HAS to be faster booting than
my Toshiba 200CDS. (100MHz Pentium, 8 MB RAM, Win 95OSR2). It takes 15-20
minutes to boot, and with absolutely NOTHING running but Explorer and IE,
89% of all system resources are used. It's the worst computer I ever owned,
and make more use of the 386-20 IBM PS/2 L40sx laptop w/ 6 MB RAM. And, I
may add it only takes 1.34 minutes to boot (Win '95 OSR2) - yes, I timed it.
Only problem is that the keyboard quit. Anyone have a replacement? I don't
really feel like paying $90 for one from IBM.
Happy Holidaze,

Hello, all:
I got a message from a German involved in the sale of a Lisa 2, and he
asked me to estimate a fair price. Not having too much experience in Lisa
pricing (unless someone wants to sell me one :-)), I told him that I'd check
it out for him.
Here are the stats:
>Lisa II
>Working (Screen unstable).
>It has a 3-1/2 floppy drive.
>0.5 MB (or 1MB; unsure) RAM
>10 MB hard disk
>Software (all in German): LisaCalc, LisaList, LisaWrite, LisaGraph
>and the manuals (on backup disks, not on the original disks).
What do y'all think?

You shouldn't need to do that, especially to get KERMIT over. KERMIT-32
(the old Macro-32'ed BLISSengized version) includes a hexengized program
and a small dehexer. You type in the dehexer (which is written in MACRO-32)
and transmit the hexengized kermit using something like MS-DOS kermit's
TRANSFER command (which sends a line at a time) then use the dehexer to
dehex the hexengized version and voila! KERMIT up and running.
FTP on over to kermit.columbia.edu or web over to http://www.columbia.edu/kermit
and look about.

I do agree that 4 MB can do a good amount of stuff (even run IE3.02 for win
3.1). Minix would be great, but my friend wanted to have Win'95 on it,
which is why I threw in the 120MB HD and 14.4 modem. I figured that since
my IBM laptop runs Win'95 fairly good with a 386-20, 120MB HD, and 6 MB RAM,
that the Tandy (486-20) would run it great with 10 MB RAM, until I
discovered that the RAM wouldn't work, and it only has 4 MB.
Would a new BIOS chip solve the problem, or does the RAM limitation have to
do with the M/B? I know in my Tandy 1800HD (same as 3800HD, but a 286),
when I put in the 4 MB chips, the computer boots, and recognizes 1 MB out of
each of the chips, then runs down a huge list of memory errors, then works
fine (after the errors are done).
If a new BIOS won't work, has anyone ever ran Win'95 with 4 MB RAM? How
does it perform?
ThAnX,

(...or should that be: "on the horns of a dilemma?")
A VERY good weekend, with the possble exception of the 'Digi-Comp' that
got away (at least for the present...)
Santa dropped a whole back seat full of assorted S-100 boards and such my
way (and I drive a Suburban, so I've got a BIG back seat!) Some assembled
units and a number of unassembled (!) kits, some still in the original
shrinkwrap/baggies!
Now the dilemma: in trolling thru the garage archives (read that: rack
shelving) recently, I came across my collection of Cromemco games (on
paper tape) for Altair (or similar), Dazzler, D+7A, and joystick. All of
which I have in the collection except for the joystick. I've got the docs
on it, just not the physical unit... Until now...
And there you have the dilemma - the Cromemco joystick is one of the
(pristine) unassembled units that came in the stack! So now, do I follow
my initial thot of building/adapting a joystick to play the games, or warm
up the soldering iron and assemble the Cromemco unit? (which would
complete the original configuration)
Sigh...
And then there is the LOCI-2 and it's 'bed of nails' card reader...
(LOgarithmetic Computing Instrument I'm told)
...and the...
Heath H-10!!!
(hah!! I finally got one!)
<BIG GRIN>
All of these decisions just before I start my Christmas vacation...

Actually I believe that Intel lost their copyright on the X86s by allowing
others to use the numbering system. In the US you have to vigorously protect
your copyright to keep it. Intel was lax and allowed the sequence to become
common words and numbers.

IRIX 5.3 and above are all Y2K compliant (providing they include the
rlevant patches).
Indigo R3000 and 4D systems running IRIX 5.3 *will* take all the Y2K
patches (there aren't many, since 5.3 was mostly Y2K compliant anyway). I
know; I did a survey on this earlier this year, and I've just finished
(literally, about 5 minutes ago) installing the Y2K patches on an Indigo
Elan for my wife's Christmas present. Of course, if you can get one at a
reasonable price, an Indigo is a very nice classic (though not quite by
this list's definition, it was released in 1991) machine. Now if only I
could get a copy of Star Office or Word Perfect for Irix 5.3...

Amongst a stack of new acqusitions today a rather interesting looking unit
branded "LOCI 2". Based on the name/serial number plate on the rear, it is
an electronic programmable calculator. Apparently built by Wang Labs.
One of the interesting things about it (to me at least) was an accessory
that came with it. A card reader. Reads cards in the IBM 80 column form
factor, but they are different. The cards (of which I received a supply
along with the unit) carry 40 columns of data, have perforated holes for
manlau punching, and are masked to indicate 80 steps of programming
information. (pictures to follow on my web site in the next few days)
It was supposed to be functional when it was put in storage (some years
ago), but it will probably be a while before I can start working htru a
pre-start routine on it.
Anyone familiar with this unit? And does anyone have any docs on it?

Ok, sounds like you're all set. If I were you the first things I'd
stick on there would be Zip and Zmodem. Kermit is painfully
slow and most installation file sets are zipped these days.
If you want to break free of the terminal server, CMUIP is a
freeware IP stack for VMS.
Good luck with it.

Hmm, NetBSD supports Microvax II's pretty well these days. If you are
more comfortable with that than VMS. (Keep the VMS license PAK's though,
you will need them if you want to reinstall VMS at some future time.)
This is the URL to the DECnet for Linux page....

I don't know if it works over a serial port connection on a Vax though....

Not AFAIK.

Is the telnet function being supplied by the terminal server and not by an
IP stack on the machine itself? Does it have a network card?
Are there any other Vaxen there? An asynchronous Decnet connection is
a possibility even if it doesn't have a network card. I'm assuming it's
running VMS? Or NetBSD?
>to the machine I'd like to clean it up, make a backup image on tape,
This implies it has a TK50 or similar. Someone on the list who is closer
to you, that has Vaxen with TK tapes, might be able to send you Zmodem
or Kermit binaries on TK50 if that's the case.
That would likely be the easiest way.
Hope this helps.

A couple of good finds lately:
A JDH Videomate a predecessor of TV cards. Which works with a VGA like
a VCR does with the 8-bits. Works but need a manual.
A Kraft KC-3 Joy-Stick ,swichable to work on an A-ll or PC with 9 and 15 pin
connector. Nicest J-S I've seen.
My main find tho was a "TV Typewriter Cookbook" from Sams by Don Lancaster, the
author of the TTL cookbook among others. Might be old hat to most members on
the list, but I find it's an amazing book. My apologies to those who've seen it
before.
Wozniac and others must have been influenced by it.
A quote (long) from the end of the book is interesting.
"
WHERE TO FROM HERE?
When this book was started, there was only one low-cost hobby microcomputer
(the Mark-8) and only one very dated tvt (the TVT-1). If you could get them,
2102's were $30 each and nonexistent microprocessor chips were advertised for
$300 to $400 each, without documentation, and the key interface and support
chips were a figment of the data-sheet writer's imagination. Peoples Computer
Company CC) and the Amateur Computer Society (ACS) were voices crying in the
wilderness.
An incredibly short time later, the hobbyist and experimenter are literally
swamped with microprocessor computers and CPU evaluation kits. Well-documented
and supported CPUs are now available for $20 each in single quantities. The
2102's are available as surplus for $1.50 each, only slightly over a tenth of a
cent per bit. PROMs have dramatically dropped in price to half a cent per bit
and less .
Computer and tvt-user clubs and groups exist by the dozens. Besides PCC
(Peoples Computer Company. Box 310 Menlo Park, CA 94025), and the numerous
smaller newsletters, major computer hobbyist magazines now exist with excellent
editorial materials, professional graphics, and wide distribution. These
include BYTE, Interface and Microtek. Universities, junior colleges,
industries, and even high schools now offer microprocessor courses. There are
now dozens of retail computer stores.
Now what? Where do we go from here? The answer literally changes by the minute.
In fact, if things continue at their present explosive rate, many of the basic
principles in this book may seem quaint or primitive by the time you read this.
Let's suppose that for an instant we could freeze time at November, 1975.
Suppose further that your main interest was not in experimenting with a CPU and
software like everyone else, but was aimed at bringing tvt's and other truly
low-cost peripherals as near to reality as possible, so that something useful
could be done cheaply with the CPUs everyone else was building. Here, as I see
it, are the major tvt-related questions that you can help answer at this
instant in time:
* Can a basic low-cost tv typewriter with cursor and memory be
built to retail at the hobbyist level for $39.95?
* Can a miniature calculator-style ASCII keyboard and encoder with
quality features (2KRO, choice of strobe, tactile response, two shot
keys) be built to retail at the hobbyist level for $14.95?
* What is the longest length and highest character quality that can be
obtained with direct rf entry of an unmodified tv set?
* Can you build a legal, universal, single-channel rf modulator to retail
at the hobbyist level for $4.95?
* What is the minimum possible cost for a snap-on Selectric base-plate
adapter and converter? How fast will it operate? Can it be made to
enter as well as print?
* How do you add light-pen feedback to graphic and tvt displays?
* Can a single microprocessor such as an MOS Technology 6502 provide all
the timing and control for a stand-alone tvt?
* What are the most effective software and algorithms needed for graphic
display games and puzzles?
* Can you design a simple CPU backup for a graphics tvt that will move
chessmen following chess notation, e.g., Bishop to King's Rook 5?
* Can you build a basic compiler on a chip or two?
* What is the setup needed for a tvt-oriented wordprocessing system to
be used for addressing, printing form letters, and so on? Can this be
done without a CPU?
* What is the simplest and cheapest dedicated "super front panel" tvt
configuration you can come up with that will read out the entire memory
contents of a microcomputer a page at a time? ? Can you make it
sequentially read out locations in hex or octa1 instead of ASCII?
* Can you come up with a simple and universal locking system for video
titling and superposition on existing EIA sync programs, both for
studio and home video-recording uses? Can you make it crawl, have
variable character size and shape, etc.?
* How do you use a tvt for printed-circuit and schematic layouts?
* What is he best way a CPU and tvt can interact with an electronic
music synthesis system?
* What about video art synthesis? Can you build a super spirograph? Make
it follow music?

Hello everyone...
I have a question:
I have a Tandy 3800HD laptop that I' trying to upgrade for a friend, with a
486-20 processor, 120 MB HD, 14.4 modem, VGA, and 4 MB RAM. It's a great
little computer, but it really can't do much with 4 MB RAM. It has 2 MB on
board, and 2 MB in (2) 1 MB 30-pin SIMMS. I have (2) 4 MB 30-pin SIMMS that
I tried putting in to put it up to 10 MB. However, when I turn it on,
absolutely nothing happens (the screen occasionally lights up). Do I need a
some sort of BIOS upgrade, or am I basically stuck with the 4 MB? It
currently has Win 3.0 on it, because even with 3.1, it doesn't have enough
RAM to do anything.

Hi. For those who remember, and for those who care, I'm back.
After coming back from my vacation to my new home in Guyana...

and then spending lots of time thinking about but not doing, I got

I remember seeing these used to develop embedded microprocessor systems for
applications like industrial control, back in 1979. I was using a Kontron
development system then so I didn't use the EXORcisor firsthand. As I
recall, it had a backplane that accepted cards from Motorola and a few
3rd-party manufacturers (cpu, memory, serial ports, etc). The cards had
dimensions similar to S-100 but were 86-pin or something like that, and of
course the bus incorporated more 6800-ish signals, like the E clock signal
used to synchronize bus events.
The idea was that you could run the EXORcisor itself as a general-purpose
computer (monitor, editor, assembler, Basic, and so on--running on top of a
proprietary Motorola OS that I can't recall) and you could stuff in any
special boards you were developing for your application and so integrate
them into your software development. When you had the code debugged, you'd
blow an eprom, pull the boards out and stuff them into their own cabinet,
insert the eprom, and start up your embedded system independent of the
EXORcisor.
One interesting thing was that many of Motorola's standalone (KIM-like)
single-board computer "development kits" like the "D2" had the same
EXORcisor bus connector and you could easily mix-and-match those boards with
standard EXORcisor cards.
I have a couple of EXORcisor cards somewhere (a Burr-Brown D to A card, some
memory boards I think?) but no EXORcisor and no documents. So if you have
documentation I'd like to take advantage and get copies of the relevant
schematics, etc. I also think I have a couple of ROMs containing Motorola
Basic that would probably work if plugged into an EXORcisor memory card.
The system you've got probably sold for upwards of $20K back then. This was
state-of-the-art professional gear, so admiration and respect are warranted
:)

Thanks to all who replied. I was concerned that if the PSs are really pulling
7 amps each I was going to run out of power really quickly in my computer
room, which is fed by a single 20 amp circuit. However, since they're not,
my 3 soon to be 4 computers, tv, and laser printer will (hopefully) all
peacefully coexist. Again, thanks. :)

Well, a 2SD350 or 380 are fairly common HOP transistors, they will certainly
run at line freq, I don't have a data book handy, but they have Ic ratings
of well over an amp. 2N3055 might work too, though I'm not certain it could
handle the frequency. They all have TO3 cases though, so mounting it might
be a headache.
If I can dig up a data book in this mess I'll see what else I can come up
with.

I don't know where you are getting this. Solaris is an "environment". Always
has
been. It includes SunOS, Openwindows, and tools. Real developement ended on
SunOS 4 about 7 years ago, 4.1.4 being the last released version about 3-4
years
ago. Also called Solaris 1.1.2. Yes, the Solaris moniker was retrofitted to
the
SunOS 4 stuff.
SunOS 5, also called Solaris 2, is running rampant as we speak. the Solaris
7 thing, well, we figured that was just to get a bigger number than NT 5.
course,
now its windows 2000. Solaris 7, aka 5.7, aka 2.7, still returns 5.7 in the
uname
commands to ensure compatibility with scripts, etc.
This is even on topic, sort of. The Sun announcement of what would become
Solaris was in 1987.
Kelly
SunOS and Solaris were seperate creatures up until about Solaris 2.4 and
SunOS 5.4 when they began merging the two into one entity.
As for the numbering scheme that is definitely weird. It's advertised as
Solaris 7, yet in the code it comes up as 2.7. Guess their marketing dept.
had an afterthought about it.

I think they're genuinely rair ;)
I also own two. The first was a hand-me-down from the Scottish university
where I worked in the early 80's. (Too bad I wasn't able to inherit the
Perq they had around then too!) I found my second Rair, incredibly, at a
garage sale in Aylmer, Quebec, only a few months ago.
Information about these machines is scarce also, although I'd expect Tony
and other friends in the UK might be in a better position to dig something
up. These rather elegantly styled micros (well, for the time: 1979-81)
originated in England. The earliest models were built using the 8085,
around an idiosyncratic motherboard/bus design (not S-100), and ran CP/M.
Mine has the most complex-looking, overdesigned switch-mode power supply
I've ever seen (although some DEC models perhaps come close). I think, but
I'm not sure, that they put 8086's into their later models.
Around 1981, I recall the British computer conglomerate ICL re-badged the
Rair micros under their own name and sold them that way for a couple of
years, probably because like many other huge computer companies they needed
to get a micro on the market quickly to regain some credibility in the new
marketplace for small computers. Somewhere, I have a reference to a defunct
American company (Drake Micros?) that sold Rair for a while. If anyone is
desperate to know I will dig up that bit of history.
My original Rair machine is I think the original design: dual floppies, 32K
ram, running CP/M v1.4 with a dumb terminal. It runs, and I can supply a
boot disk for this model.
The other machine is a little more recent and is blessed with a hard drive
and is supposed to run CP/M v2.2 --but it won't boot. The hardware design
is quite different from the original model, and my v1.4 floppy won't boot
up this machine. So, if anyone can provide a system disk for this beastie
I'd be very grateful.

When I was a kid, (<7 y.o.) I wanted my drill to be just like my dad's. So
I tied a piece of string around the handle, tied a paper clip to the other
end, and plugged it in. Luckily, we had flame retardent carpeting and a
good family doctor.
Recently, my idiot sister's idiot dog bit a woman who worked for a

Hi everybody-
A while back I got an Iomega Bernoulli Box at a hamfest, along with a big
stack of cartridges. It's almost the exact same size, shape, and style as
an XT, with dual 10MB 8" drives. I also got the sort-of-SCSI host adapter
card. I didn't worry much about asking the guy about drivers, because,
hey, there's a bazillion Bernoulli Box users out there, right? Wrong. I
can't seem to find anything of use on the web, Iomega's site doesn't yield
anything except that the drivers that sound like they should work, have a
line buried deep in the readme file that says that they don't support 8"
drives. So, I ask:
Does anyone have the drivers for Bernoulli Box 10MB 8" Alpha drives? I'd
really appreciate a copy.
Thanks,
Richard

Here is another small addition to the list of interesting machines that
may be scrapyard-bound as January 1, 2000 approaches.
Evans & Sutherland have recently sent a letter to the owners of ESV
workstations indicating that these systems will suffer catastrophic
failure (i.e, will refuse to boot) after January 1, 2000 due to a Y2K
problem with the system's NVRAM. The ESV is a quite nice UNIX-based 3D
graphics workstation, and many of these systems are still in use running
specialized software (such as the 'O' molecular modeling package). E&S
indicate that the Y2K problems with the older VAX-tethered graphics
terminals are all in the "nuisance" category, but the warning message is
certain to send many of these machines that remain to the scrapyard, as
well.
SGI also does not certify any of their systems with 68K, R2000, or R3000
processors to be Y2K compliant, presumably because they cannot run IRIX
6.5. Watch your local scrap dealer for IRIS 2000/3000, 4D series, and
Indigo R3000 systems.

What voltages are on the transistor in the working unit?

<Hi. Just a quick question which is kind of off topic - with switched powe

7A@115V... an 800w PS???

The input current is load dependant above a minimum current. If that 7A
PS is real I'd expect a minimum of .5A-1.5A at near minimum load.
Plain english, input current is proportional to load current plus some
internal losses.
If it helps I have 6 vaxen on the same 15A line. Three 3100/M10E, one
3100/M76, two VS2000, BA123 MicrovaxII and one BA23 MicrovaxII. Worse
case numbers would have me using a 25-30A line. Real numbers are far
lower. Also the 3100 PS is only some 160W but if the aux outlet is present
for say a monitor then there is +3-5A added to the input current for that
outlet. So it's easy to have a spec for 7A but it's likly allowing 3A for
a monitor or somesuch.

I think that manufacturer's code may be wrong in the manual. I can't find
any other parts with that code but I did find that a lot of the 1854-xxxx
transistors are made by 86684. I looked that up, it's RCA, Electronics
Components and Devices Division in Harrison, NJ.

It probably has a 7Amp fuse inside, so the 7 Amps is just the max surge
current. Even then most PC power supplies have less turn on surge current
than a color TV because they have a negative temp coeff. surge resistor in
series with the power input. Many TV's I've seen do not.
Because of lower power disk drives, most PC's draw much less power than one
may expect. Feel the air flow exiting from the PSU to get an indication of
the heat load. Take out all the computer stuff from the case and put a light
bulb inside as a comparison. One can also measure the currents on each of
the DC leads (with an adapter because there are, for example, multiple 5
Volt leads).

Lots of things in many Unix versions are potentially non-Y2K compliant --
anything that handles date input/output in ASCII could be, or anything that
depends on a RTC chip that only stores the year as two digits. Common
culprits are at(1) and date(1) but SGI have a list of issues on one of
their support pages, as do Sun and some other vendors.

Mind Walker wasn't just the name of a browser (which, incidentally reverted
to the original title of "Voyager"). It was the name given to a new Amiga
that Amiga Technologies, the Escom subsidiary were releasing. The system was
to include a 68030 processor, CD-ROM, and 500Mb+ hard drive as standard.

At University of Texas Center for Space Research in the late 70's, there
was one continually logging data to tape off a nasa communications line as
the data arrived. One of my jobs there was to switch the logging to the
other tape drive and dump the full tape to the PDP for data-processing. The
tape drives were pretty reliable and pretty easy to use. Sorry for the late
reply, I'm getting a bit snowed and behind on the *really* important things
in life, like reading my classic-comp digests. Also, they did not let me
keep the manual, and I do not remember how to operate the machine. :-)

What does an E&S PS-300 look like?
I saw one last Friday. Or part of one. It was a large monitor
with the tag "Evans and Sutherland PS-300" and a digitizing tablet
of some kind. There was a large cable coming from it with a round
connector and a dozen or so conductors. I expected it to be connected
to a large box containing the computer power, but didn't see that,
nor any keyboard. It was for sale for about $20 at the UW-Madison
surplus store. It was so large and appeared to be missing the
main components, so I didn't buy it.
There was a Sequent S27 parallel computer there, too. I don't
know how many nodes it had.

I don't think it is. It's not a browser. It's a search engine

Hi,
Thought I'd let ya'll know that there is an IBM Display Writer,

I also saw some other stuff, like a big IBM 5360 CPU (the
size of a washer & dryer) for $1, an IBM 3174 server for
$5, an IBM 3274/1C printer for $1, an IBM 5262 printer for
$5, and an IBM 6360 dual 8" floppy drive unit for $5, all
at the same place.
Operating condition on all this stuff is unknown.
Write me off-line at "aknight(a)mindspring.com" if you're interested
in this stuff. It's all too big for me to mess with. Well,
maybe I could snag the DisplayWriter to trade for a really
interesting calculator ...

That's what I'm asking. How do you save to floppy on a Daybreak?

Well, file extensions is questionable. In MS-DOS and relatives, these are
very severely misused. On a Macintosh, they're hidden from the user, and all
nice and neat. Until you want to change something, when you regret that it's
all hidden. In Linux, there are no extensions as far as the system is
concerned, and I must say, I don't miss them at all.

Yes, I sort of like that thing too. I had about an hour of experience with
an e-Mate (a Newton with a bigger screen and a built-in keyboard), and
though it was somewhat disorienting (there is no distinction between an open
file and a stored file, so I was trying to close the word processor for
about 10 minutes before I realized that the concept didn't exist), I thought
it was pretty neat.

You can't begin to imagine how lucky you are! Around here, I've met only a
dozen or so people who have any interest whatsoever in making things (not
including artists, there are plenty of those). I'm tempted to reduce the
number even further, considering how many of those people have never held
a soldering iron.
The other problem is that those books tony mentioned which started this
discussion are no longer easily available. What is are stupid little kits
like 'build your own radio' that come with some stencilled cardboard and a
PCB. All you have to do is to cut the cardboard, fold, glue, and stick in
the PCB. You've made a radio. And this way, people miss the point. I think
I missed the point, now that we're having this discussion.
I have one example of a 'do-it-yourself' book from 1935 called 'Making
Things for Fun' by Frederick Collins. There are lots of nice things in the
'Other Books by Fred..' list. Anyway, in this book, there is a chapter on
making a small radio receiver powered off an AC line. And the book says,
"for all ages". We don't have these things anymore, it's hard to learn.

Unfortunately, lots of "fundamental" knowledge gets left out when you
skip electric lights and go to things much more complex.
Clarke's law says that "Any sufficiently advanced technology is
indistinguishable from magic", but as far as I'm concerned light
bulbs, batteries, and wires still have an element of magic. The
concept that by connecting these two pieces of copper, I can make
a bulb elsewhere glow, is magic in itself. (Even more magical is
what happens when you short out the turns of a hand-cranked magneto
and try turning it...) One has to understand these basic elements
of technological magic if anything worthwhile is going to be done!
Unfortunately, in today's world of glitzy computer graphics and
sound everywhere, many kids feel that somehow unless their creations
live up to to Hollywood standards that they aren't worthwhile. And this
attitude is completely wrong. But talking with educators from
the local kindergarten right up to the Provost of Caltech, I've
come to realize that this is a very real obstacle to teaching
the fundamentals of not only technical subjects, but also of artistic
subjects.

Well, I downloaded both Squeak and 'Smalltalk Express'. Squeak is
certainly more complete, SE tries to be an IDE of Smalltalk which isn't
what it's about. However, it seems that both use lots of RAM. I often get
out-of-memory errors when trying to multitask under Win95 with either of
these running.

There's little need to make coils these days, and wiring electric lights
isn't very fun when one can play around with things millions of times more

no, os2 used web explorer and i like it. seems faster than netscape and IE. of
course, previous versions didnt support frames either. grrr. os2 had
explorer and start before ms copied those ideas too...
I saw a Tektronix T4002 "Graphic Computer Terminal" at a junk auction place
near here.
Had a big weird looking joystick and what was labelled a "Teletype Port
Interface" for a DG Nova or Supernova computer. Also a hard copy unit nearly
as big again.
I don't know if it was sold. If it is still homeless next time I see it, how
important would it be to save it? It's a lot bigger than most of the stuff I
pick up so please tell me there's lots of them left.

WebCrawler !!! Is that the original browser that came with OS/2 Warp?
You still use it?
I just got this curious item from somebody. It's labelled LORAN C
NAVIGATOR on the back. I haven't powered it up yet, but I guess this is
something similar to GPS (only LORAN is on the ground, isn't it?). It
looks pretty old, and certainly has digital electronics in it. Could
someone tell me what to do with this thing? Would it be useful in a car or
an airplane? (I have neither)

I've been trying to clean out the basement for the last year without much
success. I've been given orders from the supreme commander to get this
stuff
out of here. I hate to just toss working computer equipment, so I am
offering PS/2 stuff for whatever it cost me to box it up and ship it out.
All equipment was working the last I used it, but is offered as is.
If you are interested in any of it, please contact me directly at
dmasters(a)prodigy.net. Trash day is Tuesday, but I'll hold the larger stuff
until the Tuesday after Christmas. If you're interested, please contact me
before then.

Hi. I recently acquired a Hyperion "portable" PC - Mac-influenced, 8086,
dual 5.25 floppies, built in 4" amber monitor. I can't seem to get it to
boot, however. When I power it up, I get a flashing cursor, and the
system tries both drives. Then I get a "DISK FAULT" error on screen.
I've tried various versions of DOS, from 2.1 to 3.3, with the same
result.
Does the Hyperion require an earlier version of DOS, or a customized
version? Or, do I just have a machine with defunct floppy drives?
Any help much appreciated.
Mark Gregory
Thanks! I'll check it out.

Hi Gang:
This afternoon I acquired the above system. There's a main system unit, a
separate unit with dual 8" floppies, a SOROC Technology dumb terminal, a
good stock of development cards, and what appears to be a full set of
documentation and software on 8" floppies.
Any info on this system, which appears from a cursory look at the docs, to
have been a development system for standalone 6800-based industrial
controls, would be appreciated.
Thanks,
Kevin

I'm attempting to gather some revision history on the old 99/4A in the
interest of having complete---if insanely esoteric---information.
If you've got a 99/4A, would you look at the bottom and mail me the serial
number and date code (to the right of the serial number and most likely
prefixed with "LTA") along with the following identifying characteristic:
Black and Silver with "Solid State Software" badge
Black and Silver without
Beige
The next step I suppose would be to identify any hardware or software
revisions in there, but so far as I can tell my oldest and newest 99/4As
are identical in all respects except external packaging.

I have never seen anything to the effect of relay systems. They are often
brought up on this list, and I have seen relay computers that looked
quite impressive. But I have _never_ seen any explanation of how a system
based on relays works. Even in the Soviet Union, where projects like
'build your own RC boat' were common in magazines, I don't recall seeing
instructions on building a telephone exchange.

Never heard of a DY86, but yes, either that or the damper diode. Can't
remember.

Sounds about right. Murphy.

I've seen 3 ohm secondaries on valve gear, so that sounds possible.
The 1930's radio it was in had a field coil loudspeaker, first one I ever
saw.

Assuming the speakers are identical, then, in parallel, the resistance of
the circuit is halved, while in series, the resistance is doubled. This
means
that for series, the volume of the sound which is produced by the speakers
is halved, and doubled for the parallel case. I am neither an electrical
nor
an electronic engineer but, Ohm's law is sufficient for this analysis.
