Now that's where an IMSAI front panel really paid off. You put
in the card, stored an FF in the first location, the panel
display show EF instead...bingo, the RAM on D4 is bad (or more
likely a bent pin or upside down in socket).

Are you sure you measured from the right ground? I have never
seen a bridge rectifier that would take 16VAC going in, then
provide +/-32VDC coming out the DC side. Connect your ground
lead to pin 50 on the S-100 bus (the rightmost side, pins 50 and
100 are signal/power ground). You should see +8VDC (roughly) on
bus pin 1/51, +16VDC on pin 2 (or 52, I forget which, don't have
a schematic in front of me), and -16Vdc on pin 52 (or pin 2).
If you still show +/-32VDC, look at the transformer, something's
wrong there (you would have a 120V xfrmr instead of a 240V one).

The list is, more or less, on topic, and I've taken this oppertuinity to ask
a question: My Apple ][ has a Language card called a "Pocket Rocket". Now,
what does this do? Does it let me write in such languages as Pascal, C, or,
on my ][+, Integer BASIC? Also, is RAM expansion avaible to increase RAM to
128K (As I've heard that it could go to...)
Thanks,
Tim D. Hotze
<Out of interest, what would a N* want with 256K anyway? Presumably,
<whatever OS it is running is pretty hefty stuff!
It ran NSdos which was pretty lightweight. and didn't care much about
how much ram there was. It was possible to run multiuser NSdos.
CP/M was commonly ported to it and 2.2 could be banked if you weren't
faint of hear and CPM-3 was designed for banked operation. MPM was a
multiuser cpm that also could use banked ram while running multiple
users.
Mine has 128k in it at current, running CP/M-2 banked.

There's some hope for classic computers from the Catweasel people.
In their FAQ, they admit knowledge of eight-inch drives, and would
be willing to add support for them and their disk formats if someone
loaned them a drive and some disks. The problem? They're in Germany.
Andrew De Quincey <adq(a)tardis.ed.ac.uk> recently posted some messages
to various Usenet classic groups regarding a project where he's
capturing the bit-level signals from a drive, and using a Java
program to decode it to higher levels of representation.
I've been improving my ANSI C tools for getting directories and
bursting disk image files for UCSD Pascal and RT-11. Right now
they work on logical-order disk images, but I want to improve them to
read physical-sector-order images, as well as Anadisk's extra
eight-byte sector-header format. Sadly, Anadisk doesn't work under
a WinNT command shell, I have to boot back to DOS.

First, you should appeal to these thrift shops to use a pencil. Some
thrift shops I haunt will pencil in the price on the inside cover,
then to thwart repricers, pencil it in again on a different page.
I've never had any luck removing grease pencil and have ended up
smearing it. I suggest you look up the Library of Congress on the web
and email them for advice if they have nothing listed for book
preservation.

Many of the old computer books I get from thrift stores have the price of
the book written in grease pencil on the inside cover of the book. I'd
like to remove this safely. Can someone point me to the right place to
find this sort of information? Thanks.

(This is from memory and unreliable) There was a proposed standard for North America called NAPLPS, for videotext presentation. I believe it was sponsored by Philips. If someone has a complete collection of BYTE magazines, I recall there was an issue devoted to videotext, circa 1981. The one clever feature of NAPLPS was that the graphics were based on floating point coordinates. Because screen sizes and resolutions would vary, positioning and sizing graphics was a problem. NAPLPS used a coordinate system where the width and height of the screen ranged from 0 to 1. For instance, to place a pixel in the center, you referenced coordinates (0.5, 0.5).
Videotext never really caught on in the US except on cable TV as a non-interactive display. I believe there are still a few videotext services piggybacking on satellite channels. They transmit on one of the unused scan lines at the top of the picture, similar to closed captioning for the deaf.
To my knowledge the only truly successful videotext implementation was the french minitel telephone directory.
Hope this gives you a place to start.

Well all the last couple weeks have 50/50 as my sources stsrt to have less

IIsi, Mac IIci (all for $15 each); all were loaded with software and worked
fine no kb's or mice with them just the boxes. A couple of servers one Dell
and the Compaq but not 10 years old yet for $10 each with no memory or hard
drives. A NeXt black laser printer for $15, NEC MultiSpeed EL with power
brick and manuals $20 at Goodwill. COMQuest PC for .80, IIc mono monitor
and stand .80, Apple IIc free no power supply with it. Atari newstyle 2600
.80,Mac 512k model M0001E will not power on .80, IBM 6156-003 Portable Disk
Drive unit,Pitney Bowes in AT style case with black 3.5 FD $10 not tested
yet, and todays finds have not been listed yet in the computer so I can't
tell you what all I got but my pickup was full. Yes I got 2 IBM 5494's
anyone know something about them ?? Thanks and keep computing John
Simon, how timely of you. I just acquired a NorthStar Horizon
yesterday which uses four 64KB memory boards (parity). Each board has
four 9 chip rows of 16KB dram. I haven't got the documentation for
this machine yet, the previous owner has it in storage with software
as well (he claims) and said he might have it for me by next week.
I'll let you know more details when I get the docs.

Hi there, guys. I've been lurking on this list for a good long while now,
and some of the recent talk of Northstar crates actually prompted me to
dig one out that I had aquired a good few years ago and promptly forgotten
about...!
Does anyone have any idea what sort of RAM cards the Horizon likes to
play with? My system already has an (albeit flakey) RAM-16 card, and I
have the remains of an old Godbout Econoram-II card, sans about half its
chips. I have *no* idea whether this card was ever used with the N*.
The machine is not in great condition, bless it; it seems to have been
robbed of a couple of voltage regulators at some point in the past, and
the full-height 5.25 drives are, I fear, past their best, and shall be
retired gracefully. I think that the PSU could do with some adjustment,
too; if anyone in the UK has schematics for any of these bits, and would
be willing to make copies in exchange for money or eternal gratitude,
please let me know!
Still, despite it's problems, I suppose I should at least be grateful
that I have at least found a manufacturer of hard-sectored diskettes! [1]
Thanks.
Simon.

Jeesh folks,
I'm really sorry about this. It may take some time for your local
DNS servers to update their cache. Until that time the Admin at my remote
ISP (the guys maintaining my DNS records), have set up a sendmail
virtusertable to forward mail from their local mail server (see
www.sendmail.org if this is greek to you). OK, so if any bounce messages
wound up on the mailing list it should stop now....

Folks,
I'm in an mx record tangle with my primary nameserver (which of
course, I don't admin). If you can get your nameserver to kill the TTL on
it's cache you'll get me, otherwise it's going to bounce until the TTL
ends. I've unsub'd from classiccmp to prevent any bounces (I assume there
were bounces <*cringe*>?). Will subscribe back once this is straightened
out....

On the list, Don was talking about the MicroSolutions MatchPoint card,
which, with its associated software, permitted reading and writing Apple
disks on a standard PC drive, and another hardware item I can 't remember at
this time.
Here's my idea. Why can't we contact those vendors that are still in
{corporate} existence and who at one time produced interesting and useful
hardware or software (examples would be MicroSolutions, or CentralPoint),
and try to purchase, for nominal $$$, the rights to produce and distribute
these goods in small quantities.
Although it would take some of the sport out of trying to locate a
MatchPoint card, for example, it would enable us to produce these tools for
ourselves, thus becoming self-sufficient in a way.

I actually stopped to notice how many e-mails I got yesterday. Over 300.
Here's what I'm going to do.
I'm going to ignore all the off-topic BS (including the off-topic stuff
about being off-topic and and the off-topic cat-fighting) and all the
suggested changes and alternates and so on.
I will continue reading whatever comes in from
<classiccmp(a)u.washington.edu> and will (occassionally) post messages (maybe
even including the occasional off-topic one) to
<classiccmp(a)u.washington.edu> as if none of this had ever happened.
Those that are unhappy are welcome to go off and start something new. Who
knows, somewhere down the road, I might subscribe to your
list/chatroom/website/whatever as well.
Those that want to keep on whining, are welcome to do so. I'll delete your
messages and somehow manage to go about my business without committing
suicide.
Those that want to talk about classic computers, great. I'll read your
messages (even the bloody cax ones! 8^) and might even have something to
contribute.
So, if you liked it the way it was (and don't let Bill fool you, he's been
doing a great job) just sit back, ignore it, and the nonsense will
eventually blow over.

This is old news. The ATARI newsgroups have been full of this
for the last couple of weeks, so I'm sure most folks here know about
it. However, Hasbro recently came out with an announcement stating
that they are going to re-release old games such as Centipede just
like they rereleased an updated 'Frogger.'
A core ATARI constituancy still exists who would like Hasbro
to update the ST hardware line. With clone European makers _still_
manufacturing ST compatible machines, and Gateway 2000's purchase of
the Amiga line, one might think this could be a profitable move for
Hasbro. Looks like they don't see it that way howver.
What a shame. Both *BSD and Linux run on this hardware line
and I _really_ want a decent alternative to PC hardware available
which is also designed with <*cough*> games in mind (hey, I may be an
adult but I still like videogames!) Maybe a letter writing campaign
to Hasbro could help change their mind? Anyone else here fond of the
old ATARI computer line and share my enthusiasm?

I have a problem with an Atari 1030 modem. While I can receive
everything correct on the Atari modem I am not able to receive anything
transmitted from it to another computer correctly. All I get from the
Atari modem is binary garbage. Can anyone help me? BTW dose anyone have
any spare Atari cables remember they have 13 pins. On another note I've
noticed that flea markets are a pretty good place to find classic
computers.
Many of the old computer books I get from thrift stores have the price of
the book written in grease pencil on the inside cover of the book. I'd
like to remove this safely. Can someone point me to the right place to
find this sort of information? Thanks.

I have to admit that I'm flame virgin, but it looks like fun so I'll
give it a shot.
I can't believe so many on the ClassicCmp List don't subscribe to
the digest! That was the first thing I did.(Change over to the digest)
I can't be sorting through 40-50 messages to find the work related one
that need to be answered right away. And frankly, collecting computers
is a hobby for me, one of many, and this is not the only digest I
subscribe to.(Even though it's the one that takes most of my mail reading
time.)
Yesterday's digest came in SIX parts. In the last year thats nearly the
record. Page after page of the same e-mail quoted again and agin.
BUT I'm not complaining, instead I suggest that MAYBE the
ClassicCmp List should default to digest when subscribing. I think
that a digest allows people the time to think out their responses.
Many of you are the CP/M-List, this is a good example. You may have
to wait 24 hours for a response, but usually it a very thoughtful one.
And I think its because (as I remember) CP/M-L defaulted to digest
and it just become a slower paced discussion.
Also with a digest there is no reason to quote someone in entirety
(You just read the other message). You do have to cut and paste, so
you're more selective.
It true than I'm sometimes 24 hours late on a computer for sale. But
then again everybody want to auction off their computers anymore.
Well that my humble opinion.

Northstar got its start, I think in late 1976, with one of the
first affordable and reliable floppy disk systems for S-100s.
It used the then brand new 5.25" floppy disk Shugart had just
started making, matched to an S-100 controller board. Up to
that time all the floppy systems were based on 8" floppies,
which went for, oh, around $1000-$1500 for a drive (and weren't
very reliable either). The NS drive was very cheap in
comparison, I think around $500, but bets of all you just put it
in the box and it worked, very rare for S-100 machines in that
timeframe.
The drive was single density, single sided, hard sectored with
10 sectors of 256 bytes each, total around 90KB. Paltry
compared to the 243KB on an 8" drive, but infinitely better than
a Tarbell cassette interface. The drive came with a crude
operating system (CP/M didn't work right away because of
hardware problems with the boot ROM on the NS controller) and
Basic. Eventually Lifeboat got a version of CP/M working with
the drive.
After the floppy subsystem, NS came out with a unique S-100
floating point coprocessor board. This was actually a sort of
bit slice state machine that did BCD arithmetic. A very clever
design but somewhat difficult to use. It was fast for it's
time. The only software that used it (to my knowledge) was the
NS basic and I think one of the CBASIC or PASCAL compilers
(Sorcim?).
NS made enough from their floppy systems that they started
making whole machines, the Horizon and later the Advantage. As
with all the S-100 companies, PC's killed them off.

Well, pretty soon you're all going to get sick of
hearing from me, so this will be the last listop
stuff I post for a couple days.
I read back through a couple weeks of archive and
I'm still letting thst digest. For the time being,
I've decided not to make any decisions ;)
It seems a little common sense and courtesy would
go a long way in bringing this list back on track.
I'm not so sure that hard-core officiating would
make any difference. It would probably just spawn
arguments defending the honor and freedom of
listmembers (heads up aspiring list operators -
that's a lesson I learned the hard way).
Even when I was actively moderating this list, all
I looked at was whether or not subjects were about
classic computers or not. If it goes a little off
track, all right. If that continues for too long,
a polite message to the parties involved usually
retires the thread to private mail. If you think
about what you're going to post to the list for
a minute or two, you'll know whether or not it
will be well received. Spend that time.
This list is for recreation. You should be on it
because you think classic computers are fun. All
of you are people with a common recreational
interest - there's no reason to get nasty with
each other. If you don't like certain people or
topics, just delete them and focus on what you
like. If you can't find anything you like, maybe
this is not the list for you.
I'm getting off my soapbox now. Thanks to all who
have sent me their input. Keep it coming. I will
lecture you more next week ;)

Allison, thanks for the reply. I am hoping to get full docs from the
previous owner (which should answer most technical questions) but am
very interested in learning about the history of the company itself. I
read everything I can find on early microcomputer companies and find
it fascinating reading.

Hi,
Can one of the vaxheads help me with this one....
I have a 3100 who's monitor just died and I want to use a terminal emulator for it until I replace the monitor (should be here in a few days). I know that I have to change one of the dip switches inside but which??? And what's the pinout of the serial printer port (that *is* also the terminal output, right?) ???
I'd kill to get my hands on some original documentation/manuals for either my 3100's or 3200.
BTW, the 3100 in question is a 38.
Thanks,
Aaron

Good heavens, another libertarian anarchist. It's people like
you who build computers in your garage instead of accepting that
only billion dollar corporations have the resources to build
computer products. Where would Bill Gates be today if he

I'm surprised that it took so little time for this list to get to this
point. Another list I'm on took about two years for it to reach critical
mass before it exploded into three additional mailing lists, all covering
the same topic (with the result of many hurt feelings, a list that only
lasted about six months before it imploded, with the original list still
going strong).
As I said to Sam in some private mail I sent to him:
I'm not sure what can be done, but if the topic of a mailing list is
held too tightly, eventually it'll die (like one of the mailing list
I host now, although there are some other reasons for that as well)
as there is little or nothing new being added.
...
I don't want to seem overly pessimistic, and yes, perhaps the topics
have drifted off a bit too much, but actions like yours (and I'm not
trying to blame or pin anything on you, this is just my observations
from about 5 years of being on several mailing lists (almost all of
them high volume)) tend to do more harm over time than good, by
splitting the community up, causing confusion, ill feelings and
political overtones.
And yet it continues (and Sam, in your reply to the above you appear sane
and rational, yet your diatribes on the list show a completely different
side, and one that isn't very flattering).
Bill may "own" the current list, but that still doesn't prevent anyone
>from starting up a new list dedicated to the same topic, only time and
resources. And perhaps against my better judgment, I'm doing such a thing
(Lord help me), and so let it be. If Sam feels that he can run a list
better than Bill, or even I, then he is certainly free to start his own and
see who signs up. Much like I am doing now.
It's there. If no one subscribes and this list continues to flurish, so
be it. If, on the other hand, my list takes off and this one dies, so be
it. Currently, the only person subscribed is me. I'm not going to add
people, it's up to you.
To subscribe, send a message to classiccomp-request(a)lists.armigeron.com
with a subject line of 'subscribe' (you might want to put this on the first
line of the body as well). That's it. You'll then recieve a welcome
message describing the rules and regulations of the list, as well as the
unsubscribe rules. If you don't like the rules, we can talk, or you can
walk.
Simple, eh?

I've been on Compuserve since the early 80s, and I tend to like their
style of management. The forum managers tend to rule with a very light
hand, in the style of a good bartender. (Another factor I believe

Huh? "Supporters of democracy deserve to get it, good and hard."
Please, Sam, it's within your ken to set up and administer a mailing
list, and you can even moderate it, which will probably take more
than an hour a day, and people will complain when you don't do it
fast enough. Sound like fun yet? Life being what it is, you'll
probably revert to the "sit back and let the flames die on their own"
approach to list management, which works pretty well, considering
the alternatives.

I'm sorry. I had no idea that my questions about the ASR-33 would
be considered off-topic by anyone. My 70s computer experiences
were nearly defined by I/O through these beasts, and they were
certainly a popular interface for DEC and S-100 era computers,

Hi there, guys. I've been lurking on this list for a good long while now,
and some of the recent talk of Northstar crates actually prompted me to
dig one out that I had aquired a good few years ago and promptly forgotten
about...!
Does anyone have any idea what sort of RAM cards the Horizon likes to
play with? My system already has an (albeit flakey) RAM-16 card, and I
have the remains of an old Godbout Econoram-II card, sans about half its
chips. I have *no* idea whether this card was ever used with the N*.
The machine is not in great condition, bless it; it seems to have been
robbed of a couple of voltage regulators at some point in the past, and
the full-height 5.25 drives are, I fear, past their best, and shall be
retired gracefully. I think that the PSU could do with some adjustment,
too; if anyone in the UK has schematics for any of these bits, and would
be willing to make copies in exchange for money or eternal gratitude,
please let me know!
Still, despite it's problems, I suppose I should at least be grateful
that I have at least found a manufacturer of hard-sectored diskettes! [1]
Thanks.
Simon.

I also have a big Symbolics and supposedly some documentation, but I
haven't opened any of the boxes so I don't know whats there. I don't
have any experience with these machines and don't expect to be able to
try mine any time soon, but other than that would be happy to share
experiences. I also have contacts in a shop that ran them fairly
recently, but they are a startup (of sorts) so don't have spare time to
hold our hands.
Corresponded with a fellow who has a complete listing of LISP 1.5, we
talked about how to get it into machine readable form so it could run on
a 7090 emulator. Definitely something I'd like to see happen. If you run
across any LISP on 7-track tape I can read it.

If they are from a 704, 705 or 709 or ancillary equipment I may have
module diagrams. Look for a 4-digit number rubber stamped on the metal
on the tube side, also there may be a 6-digit part number. To get an
idea of what machine they might be from list the tube types. For
instance, the higher performance 704/709 modules used mostly 5965's in
the processor. Also look at the parts on the sides, logic modules have
resistors and lots of diodes and maybe a few inductors. Other modules
will have few or no diodes. One common module from card equipment has a

If I send any of you messages, I would expect that they
will be held in confidentiality. I will certainly give
the list a chance to input before making any decisions.
If I wished to communicate to everyone, I would post to
the list.

Yesterday I began talking to people about taking over list
functions. The response has been amazing and overwhelming.
Before making any decisions, I am going to go over the
list archives and attempt to read the list for a week or
two to get a feel for what's going on. If you have strong
feelings about how the list should be run, or by whom it
should be run, please e-mail me directly.

:::cautiously leaving bomb shelter in order to post:::
back in the 1980s, i came across a book that also had a design for a robot dog
but i think this was a different book. it was built around a 8085A and 8155
support chips, totally wire wrapped and included schematics for building a
programmer to program the robot dog itself. i never did get around tuit, but
would have been fun to build. why didnt robots catch on as big as computers
did? i remember robots were the thing back in the 1980s like the web is now
but never really gained critical mass. there were a few models made, ( hero 1
and 2, rb5x, et al) but nothing really caught on.

Not a lot. To keep it simple there's no 'learning by experience' (the
book does mention this in passing) or large memory stores (using only
valves and relays, that's not suprising). Looking quickly at the book I
can find :
1) Detecting/following a light source (turning its 'head' towards it,
moving towards it).
2) Detecting a sequence of 2 tones (its 'name') and coming towards the
sound source
3) Detecting that it's walked into something and backing off.
4) Detecting a hot object ('food'), turning its 'head' towards it,
licking it.
5) Using a sonar (accoustical radar) system to detect objects and avoid them
OK, trivial compared to what can be done with even a PIC microcontroller.
But I'd still like to make one one day....

I just acquired a couple of Osborne 1's and one of the two of them has a
Drive C: in it. I got some docs with the boxes but nothing describing
this exciting little add-on. I've scoured the classic computer mailing
list archives and I've found a previous question (from may of last year)
on just this topic, unfortunately nobody really knew anything then. Any
help or pointers would be greatly appreciated.
Cheers and thanks,

To tell you the truth, I don't know the first thing about these drives. I just
got one for free a whilke ago and was really just wondering if the damn thing
worked or not.
I'll let you know what i find out tho...

In no particular order:
Friends and Family (and the companies they work for)
Thrift shops
Garage Sales
Dumpsters
Surplus dealers
Internet (this list, especially)
hamfests/swapmeets/fleamarkets
classified ads
typewriter/office equipment repair businesses
Okay, that's only nine. Sorry.

I know of them from the computer graphics market. (I'd love to get
one, if you have two. :-) I think the 3D modeling / rendering
software was sold off to various other companies (Triple-I / Autologic)
and these days at least the concept of a Lisp-based modeler can
be found at www.nichimen.com .
The symbolics.com domain is still registered, and by reading between
the lines of some messages I found, I think it's owned by some
Symbolics enthusiasts or employees in Princeton Junction, NJ.
There is/was apparently a related newsgroup or mailing list. Go to
www.dejanews.com and search "info.slug" (with the quotes). I found
a message that said that Symbolics had laid off its last three
employees just this past January, and that the lawyers are
fighting over the assets.
Good start on your Lisp history page. I have one for UCSD Pascal.

I've got a spare SQ 555 as well as about a dozen carts that I'd
be willing to let go... a trade for something nifty would be great!

Hi, folks,
Like most of the list subscribers, I'm a scrounge. To this end, I've
placed on my web page listings of electronics and computer-related surplus
stores and swap meets in Washington and (northern, Bay Area) California.
Oregon (Portland and Vicinity) will be added as soon as I can swing a
survey trip there.
Hoping these listings may be of use to at least a couple of you, the URL is:

Or...

Enjoy...
