A friend asked me about what he says is an IBM unit that is running
Windows 3.1 and he says it says a type 4836. That number isn't clciking
with me, anyone have any ideas of what this is, or is he possibly
reading a tag from an add-on/in card? I saw a reference in IBM Finland
to a 4836 multiplatform emulation card but nothing else.

Wasn't RCA started as some sort of "holding" company, that didn't
manufacture products of their own? They first sold items made by (you
guessed it) General Electric and Westinghouse. Later they acquired
Cunningham who were also making vacuum tubes/valves and included them in the

Hi!
I've got an old Tadny 600 laptop that I used to use for quick note-taking.
I "retired" it about a year ago when the battery would no longer run the
floppy and I had been given a Tandy 1400HD. Since then, the hard drive
controller in the 1400 has "lost the magic smoke", and I'd like to get the
600 running again. I replaced the NICd cells, charged them overnight, and
pressed the power switch. What do I get? Garbage filling the screen. I do
the 5-finger salute cold boot. Here's what I get:
--------
Uncoop System Load: Disk Error. Retry (Y/N)? _
--------
Disk error? from what I remember, this thing booted from ROM, and I don't
have any sort of system disk. I hit n.
It turns off. Great. I press power again, get two beeps, and this in the
center of the display:
--------
Unable to restart, critical system data damaged.
Hit any key to reinitialize system.
--------
Wonderful - system data damaged- doesn't sound good. I might as well hit
any key - can't get any worse. I hit "enter". To my surprise, I get the
old, familiar Microsoft Works 1.20 screen. I use the arrow keys to move the
cursor over "WORD", and hit enter. At the bottom of the screen, it says:
RUN application: WORD
That's where it's been sitting for 5 hours, because I can't turn it off,
either.
I also noticed that the "free memory" said that there were 976560 bytes
free. A year ago, there was only 32k.
Anyone have any suggestions?
ThAnX,

So..... what little space remained in my living room is now
occupied with to big racks of Prime system.
Its got 1 CPU, 48M of RAM, 32 ports, a Seagate Sabre, A Century
300M, a CDC 9766 top-loader, and a Kenndy 9100. I have many reels
of tape, and about three linear feet of operating documentation.
Maybe this weekend I can cable it up and light the fires.
But since I am mostly a DEC collector, I have no idea where to
start looking for Engineering and Maintenance docs on this machine,
and I have not had time (yet) to sift thru the Web for clews.
If there is, by chance, someone on this LIst who has leads to
Prime engineering printsets, I would be mightily pleased to
communicate with you.
From spending the last few nights reading the OS stuff... I am
impressed by the simplicity of the user interfaces and the operator
environment... just the thing for a CompuDummy like me.
Thanks in advance... pix of the Device will be loaded up to my
neglected webpage this weekend (honest!). www.lightsound.org

Why not Forth? Simple, interactive and gives immediate feedback. It also
has "high level" constructs, no GOTO, but is "low level" at the same time.
My six year old son loves it. The RPN style didn't bother him a bit (why
would it when he knew of nothing else?)

No personal aspersion on Chuck's plan, but in both Sam's dad and
many other parents I've seen, the curriculum (in general, not just
computer-centric) seems to be driven by the parent's interests
and perhaps the child's own natural interests are forgotten.
My three-year-old likes to doodle on my Pilot and PC, but
something inside me wants to let him be a kid for a while,
as opposed to pushing him to become the latest "youngest
NT certified engineer." When I furnished him with an old Mac SE
with a kid-paint program, he enjoyed it, but after a while he
removed the mouse and used it to lasso his fire truck until the
magic smoke left the mouse. Yes, there's a 100bT port in his
bedroom, and a T-1 to the house, but I haven't told him about
that yet. It's scary how the words "e-mail" and "dot com"
worked there way into his vocabulary, though.
I flinch when I see how computers are used in schools. I help
the local school board with some technological issues, and recently
took a tour of the new network wiring at the high school. They've
got fiber to the closets, DS-3 feeding the place, video distribution,
it goes on and on. "What's it going to be used for," I asked
the director. "Well, it might be ten years before we get the budget
to refurbish, so we thought we'd ask for as much as possible, and
we'll let the teachers figure out how to use it."
Meanwhile, the teacher's union is requesting funding for substitutes
so that teachers can take mornings and afternoons away from their
classrooms in order to attend seminars to learn how to use the marginal
Win95 machines they have now. Meaning, of course, that they don't know
how to use what was installed from the last round of funding.
The only use of the Net I saw on the tour was five kids in the library,
surfing sites about their favorite bands. Surprisingly, the "porn filter"
consisted of keeping the monitors in sight of the librarian's desk.
Of course, we all know the Web is peer-reviewed and scholastically
approved, so any material you find there is OK to cut-and-paste into
a book report.

The problem is that we need to know a little more of the system
configuration first... do you know exactly what the system has?
If you know it has MSCP disks, then we need to know how they have
the partitions setup.

As someone else has already mentioned, a Doc set is something like
US$1300+... I doubt hobbyists will run out and buy it... that's
why the best you can probably hope for is someone who can let you
1) borrow, 2) have, or 3) copy select pages/manuals of their doc
set.

Any advice on how to attach a paper tape reader to an IBM compatible

Sounds crazy, but we run some software from paper tape...would be easier

it were on disk.

6 bit characters were quite the standard BEFORE /360 days, say for
CDC 6600, CDC 7600 (the most powerful computers from mid-60s until
the appearance of the CRAY-1 machines, forerunners of the Cyber 170 series),
or IBM 7030, IBM 7090, IBM 7094 say, back in the '60s.
They were not called bytes, and could not be addressed directly;
there were 36 bit or 60 bit words, and shift / logical instructions used for
character manipulation. In fact this is probably the origin for the
six character namelength limit in FORTRAN IV : 6 chars x 6 bits = 36 bit word.

I remember that *My* first computer was a 286-16 with 4 MB RAM, DOS 3.3, a
1/2 x CD-ROM and a 360k floppy.
The keyboard was missing a few keys, the case (XT) had gotten rusty from
sitting in a damp basement, and I had found the EGA monitor in the garbage
(I had to replace the power cord).
It didn't have a mouse, and when I finally was given an old mouse, I found
out that neither serial port worked.
I eventually bought a serial card for $1, and a copy of Windows 3.0 for $10
(on CD, in 1992). It was the first program that I ever had on CD.
It took 5 hours to install.
The printer was a Tandy DWP ][ that I was given by someone who got rid of
their TRS-80. Instead of buying a cable for it, I ripped the D-connector
out of the fried serial board and made my own cable.
I used Windows Terminal to connect to a local BBS with a 2400 manual-dial
Racal-Vadic modem that I found a Salvation Army for $3.
The computer was running up until two years ago, when the HD crashed
(heads?) and a cloud of tan/orange smoke billowed from the front of it. I
pulled the serial card, CD-ROM controller and video card. I gave the
monitor and vid card to a cousin that was building a computer, the
case/MB/floppy/HD to a computer recycler (since out of business), and the
CD-ROM is still chugging away on my 5170.
I think that entire system cost me about $20.

How is that as easy as ROM BASIC? You turn the computer, and Visual Basic
pops up immediately? I've yet to see such a computer (and if I do, I'll

We're talking about teaching _about_ computers, not teaching _with_

Haddock's book is A Collector's Guide to Personal Computers and Pocket

Books Americana, Florence, Alabama, 1993. ISBN 0-89689-098-8.
I found it useful as a reference, but dated; it doesn't include many
machines after the Amiga 1000, and the prices are way out of date. Also,
the information about many machines is incomplete (e.g. no production
estimates, original list prices, details). The book also has a lot of
material on 70s vintage hobbyist machines and peripherals (e.g. Altair,
IMSAI, many more obscure others) that are largely unobtainable where I
live. Still, fun to browse through, and one of the few references available
for our hobby.

A disk block has gone bad. Either the rebuild process was unable
to read a block or unable to write one. Either way, the on-disk
structure may be corrupted (someone more RSTS-saavy can explain
more). The bad block is block 1 -- the home block... not good.

I went computer scrounging today and found a brief case style tool box with
some kind on IBM tester in it. I have so idea what it is but it has an 8"
floppy disk drive in it! I got the floppy disk too. It has a NICE handset
with a 4 line LED display and a full keyboard attached by a cable. There's
also a lot of strange looking connectors and adapters with it. The main box
has an "IPL" button and three connectors labeled "PIO", "S LOOP" and "R
LOOP". The quick reference chart only calls it a "MD". There's a tag on it
that says "TYPE 910x 002". Anyone know what it is and what it's for?

One of the main problem in getting a kid interested in one machine is not
really at the level of what they can do with it but more IMHO to what
machine they are used to play with.
My daughter (4) and my son (2) are both used to play with thepentium running
Winblows. If I show them a game on a c64 or Apple ][ or any other machine
for that matter they look at me weird and ask if they can play with the
pentium since I'm not using it...
I belive that if a kid is interested in programming (mine are not yet:( it
is better to let them choose what machine they are attracted to. I don't
know yet whether any of mine will have any interest in old machines but for
the time being I'm just happy that they show any interest at all in one of
them. What I'm trying to do is show them as much as I can (or as much as
they can take) about other machines. I'll let them choose what they want
later if they keep the interest.
I can see ten years from now trying to tell my son that the C64 had an 8X1
byte for sprites and having him replying ok but how do you do hollographic
simulation?
Of course skill learned from old machines are valuable to understand what's
going on inside of the machine but the trend today is to make abstraction of
all those _annoying_ facts and use the proper library or API. (I work with
Winblows programmers who have no clue how a computer operate)
So I say let the kid choose.

I dont know RT-11 (yet.) and am looking forward to the experience. But
before that happens the seller wants to purge some sensitive employee files
on the system. Can someone tell me how to tell him to 1) move through the

Where can I find a good source of RT-11 info?

It does. I was confused when I heard about people complaining that an HD20
wouldn't work with their 128, because it works fine with mine. Then I
realized that mine was upgraded to 512k.
I believe that there's not enough room in a stock 128 for the HD20 init,
plus the buffers it needs, plus the rest of the operating system, plus user
apps.

Despite which fact, in PET BASIC the CODE function is replaced by the ASC
function.
But I think you missed my point. Was I really that unclear? Let me
rephrase:
The decision to use left arrow for that code was sensible because the
PETSCII character set has underscore elsewhere (and I still maintain it is
at shift-$ on the PET keyboard. FWIW it is indeed one of the Commodore
line drawing characters, but I used it as an underscore in many text-based
PET applications when I programmed the machines regularly, and I still use
it as underscore in PETSCII-ASCII translation), and it would therefore be
redundant to include another underscore character in the character set.
If you ever get the chance, have a look at the layout of a PET chicklet
keyboard. It is quite clever. PETSCII, unlike ASCII, _does_ make
connections between codes for shifted keys and those for unshifted keys -
on the original PET keyboard the PETSCII code difference was always 128
(the screen code difference was always 64 BTW). And yet they managed the
following things:
Characters with horizontal lines of pixels in all eight positions followed
a simple route down and up two adjacent columns of keys, yet they managed
to get bottom (shift-$), middle (shift-@) and top (sorry, can't remember.
Shift-# ?) onto punctuation keys so they would be available in lower case
mode. Similarly with the vertical lines in all eight pixel positions.
For those pedants who say there is no middle with an 8*8 dot matrix, it was
the one that lined up with the small corners and tees (shifted numbers).
Large corners (two outer edges) were in a little block on shifted O, P, L
and colon (or possibly semicolon). Shifted O, P and L were of course
unavailable in lower case mode; shift-: became a square root sign.
And so on.
So although PETSCII is not ASCII, don't knock it. It worked well.
Philip.
PS Why is it that, whenever someone misunderstands what I say, they assume
I'm wrong, and they're right. And if their interpretation of what I say is
obviously silly, they berate me for saying something obviously silly,
rather than stopping and thinking, Can he really have meant that? Nothing
personal, I hasten to add. It happens all the time. P.
What boggles the mind is that this is a problem at all. It seems hard to
believe (in retrospect) that people really did deliberately build software
with only 2 digit years. I know it saved a few bytes, and yes, I remember
when a byte of memory was a significant amount, but still. How did standard
programming practice come to be so short sighted as to assume that software
infrastructure would be thrown out and replaced on a regular basis?

I picked up an auction lot today and it contained, among other things, some
5.25" disks that are hand labelled as "1.2MB Test Media". I'm wondering if
they are calibration disks for 5.25" drives. Realizing they are probably so
RARE that to L@@K at them should cost $20 :-) Since I've got a couple I'd
like to send one to anyone who feels confident they can tell me what they
are (Tony?)
Another thing this lot had in it was the 1996 MSDN developers network
subscription CD binder. This basically has like all the "big" software
microsoft made including copies of Win95, WinNT 3.5 and WinNT 4.0 Beta.
Plus various SDKs, international versions and docs. It occurred to me that
to a developer this "trash" is going to be gold to a collector in 20 years
who is trying to demonstrate or renovate a "pre-millenium personal
computer." So it seems to be out there and it is fairly low volume (less
than 1 cubic foot) and can be had inexpensively. May I suggest we do future
collectors a favor (as those who saved OS/8 did for me) and take some of
this "junk" and store it somewhere safe for future generations...

It's from around 89-91 era, so it might be. I have a couple. One built in
89, (A Classic!) 1 in 90. It's a medium sized Vax, about the size of a very
big fridge. The 300 series cpu's were good for about 3.8 VUPS (1 VUPS ~
1MIPS). The middle digit of the 300 indicates the number of cpus in the
system. Depending on individual machine config, this could be anything from
1-4.. The internal tape drive would be a TK70, a 280mb version of a TK50.
They will also read TK50 tapes but not write to them. A typical 6000-310
would probably have 64Mb of RAM, and an ethernet adapter, plus it may or may
not have either a KDB50 SDI Disk/Tape controller and/or KLESI-B controller
for TU81+ tape drive. It could also have instead of a disk controller a CI
bus adapter to allow it to use HSC mounted disk/tape drives in a VAXCluster
configuration. Apart from the size and weight, if you have the room,
they are a good, reliable machine. VMS or Ultrix only. NetBSD not
supported (No XMI Bus support). They are 3 phase, but it's fairly easy to
convert to single phase, and they only consume around 500w. My 6000-220
(slightly slower, but a 2 cpu version) draws about 2A @240vac from a
domestic power outlet. FWIW, it can be moved by hand, though it takes
about 6 guys, weighs about 200Kg, about 30 of which is a 3 phase
autotransformer in the bottom. (First thing I get rid of!) They need a
VTxxx terminal as a console.
One of these was my first Vax, so I guess I'm sort of an enthusiast. Oh
yeah, they are just about unkillable, dropping one from a great height will
distort the cabinet somewhat, but it will probably not stop it working.
Hope this helps.

All,
Right here in Figure 5-6 of NASA's Technical Memorandum 4527,
Natural Orbital Environment Guidelines for Use in Aerospace Vehicle
Development, it shows that the Cosmic Ray environment is actually *less*
severe during a solar Maximum than during a solar Minimum. Note that the
effect only applies to rays with energy lower than appx. 10,000
MeV/nucleon, and these would probably be screened out by the atmosphere
anyway for a surface observer or classic computer. The rays packing more
than 10,000 MeV/nucleon are unaffected by solar max/min.
I surmise that when the sun is putting out lots and lots of
protons, the extra protons form an additional layer around the inner solar
system and screen out some of the cosmic rays. Of course, this means that
though there are fewer (low-energy) cosmic rays, there are more solar
protons - but their energy distribution falls off rapidly above 10,000
MeV/nucleon (per Figure 5-7c).
The bottom line is that unless your classic computer is on orbit,
you won't see any particle radiation effects from solar max. Magnetic
storms affecting power distribution grids, particlarly far north, quite
possibly.
On another topic, I salute Captain Napalm for his multiply-encoded
message. Chuck, I disagree with you with less vehemence than he - I'd
rather see text messages myself - but that was a *hilarious* rejoinder.
Well said, er, shown, er, put.
On yet another topic: I spotted about a month ago (and finally
found my notes) the following gear at a local electronics shop (A-Tex, near
the airport in San Antonio, Texas).
2 ea. HP 1615 A Logic Analyzer $31
4 ea. HP 1610 B Logic Analyzer $31
1 ea. Tek. 4105 Monitor $10
1 ea. Tek. 4404 Monitor $10
1 ea. Tek. 4025 Terminal $10
1 ea. HP 1611A logic state analyzer $?? (not marked)
Each unit was about the size of a CRT terminal. The 1611 looked
like it might be an in-circuit emulator for a Z-80 based on some other text
on it. Conditions all unknown, no probes or accessories or manuals.
Outsides were dirty and scarred, with some keycaps gone on the terminal.
A) What are Logic Analyzers? (This is an embarassing question. No need to
coddle me with a long answer, something like "please go *open* the Horowitz

Anybody know the frequency ranges for these particular units?
Could I have fun probing the inside of my Rainbow or Mac Plus with them?
Could I have fun probing My friends' PowerPC computers?
Are these good prices, assuming they work?
B) What do accessories for the logic analyzers (like probes) cost? Can I
still get manuals? How could I test these in-situ?
C) Is anybody interested enough in any of them to have me pick one up at my
next opportunity and ship it (your expense for shipping, could be some time

There are third-party GUI's possibly available for QNX but they are costly.
Wonderware's and Intellution's interfaces are around US$2k minimum for
example. There may be others cheaper nowadays. These GUIs are typically
refered to in the industry as Man-Machine Interface or MMI.
QNX is a small realtime OS for control systems. Applications are nearly
always handwritten for each installation often using a third-party supplied
MMI, etc. No typical desktop apps available for QNX as far as I know. I
know little about QNX and my books and catalogs are still packed in boxes
after my untimely "downsizing" last year.

>There are three fans inside the box, but it's sealed. I always thought

>fans inside a sealed box?
The industrial environment is quite tough for electronics. Depending on the
factory/machine/process, much muck could be drawn into an electronics
enclosure by air circulation. In machine shops as an example, tool coolants
which are sprayed onto the workpiece and tool are found in the air as an
aerosol mist. The aerosol is pulled into a cabinet by the fan and collects
on everything. Over time there is a coating of condensed coolant which
collects dust and other garbage and prevents proper cooling of critical
components. I worked on a 1978 vintage 6800-based CNC controller (not 68k,
but Moto's 6800 :) which had this cooling arrangement. After about 12 years
I found a 1 mm thick coating of sticky coolant glop coating most everything
that was not even close to the airstream of the cabinet cooling fan. Poor
idea. A standard PC used in most machine shops is even asking for trouble
after a period of time.
Sealed Boxes Are Good. Cooling is achieved by thermal exchange between the
outer surface of the enclosure and the surrounding atmosphere. Fans inside
the box ensure the air is mixed to maintain contact with the inner surface
and to prevent "hot spots".
On systems which had to have a LOT of electronics, especially high power
motor drives and a CRT display, etc. a refrigerated heat exchanger system
was hung on the outside of the cabinet with its cooling surface stuck
inside the enclosure. Another lower cost, simpler way is to use the
venturi-effect which uses filtered compressed air blown through a venturi
thus cooling the air and pressurizing the control cabinet. Air was
exhausted _out_ of the controls because of the positive pressure inside.
Really old machines actually had a small air conditioner placed inside the
cabinet.
Usually when I built control systems I made sure I could get as much
surface area as possible exposed to the outside world. I used cabinets
somewhat larger than needed, air moving within, free space around exterior
and absolutely no open apperatures to let junk in. Insides were kept clean
with fewer electronic failures.
Some non-industrial computers that have no fans, especially lo-cost
mass-market types, probably had their cases made such that free flow of air
around the exterior would help cool things off without relying solely on
their vent holes and slots.
>

Hard to tell without knowing something about the software written for the
thing. Of course, it is not hung on the original machine at this time so
there could be some sort of interconnection which would keep the controller
running. Though the display blanks this could be related to a feature in
just the display panel, not so much the controller. I feel the CPU is
halted early on as there are no periferals to be found, so the OS hangs
thus not keeping the display 'alive'.

24/7 is the norm for most industrial systems. The power switch for this
machine was likely the big disconnect switch on either the machine or the
wall from which the AC power was run to from an overhead busbar. You never
shut it off unless there was an extended plant shutdown (long vacations) or
machine repairs.
I haven't got Netscrape back up yet because of a disaster with windoze95
(GRRRR! Don't get me started on this damned OS which cannot handle system
problems correctly. The crash was incredibly uncalled for and troublesome.
Grrrr.....) but I would suggest searching for a QNX website yourself. They
could have some bits of info for you to pick out. Otherwise, as an
"unlicensed end user", you may not get any direct help from them. They will
likely send you to a local sales rep. Depending upon how sympathetic he/she
is to you being a collector type you _might_ get a little assistance or
even a few bits of documentation.
Good luck.

Ok, well, one of the criteria of the Patent office for
registered 'firsts' is that it must have utility! What
makes it fun, promising, useful as opposed to an
academic intellectual curiosity?
We read about early logic devices with interest, but
the Simon seems to lack a certain critical mass to
generate widespread enthusiasm, it's basically an ALU
unit. That's like claiming a horizontal output unit,
affordable to a home user, was the 'first TV',
even tho a sophisticated hobbyist could buy it and use it
as a part of a larger project that could actually do
something useful. There's nothing really there that would cause
thousands of hobbyists to get excited over the possibilities
enough to rush out and plop down four grand and swamp the
manufacturer with so many orders they couldn't keep up.
But we want to know more - was the tape program storage,
could it make decisions and branch based on comparisons,
scalable, etc.

The US could have hundreds of millions of dollars by doing that (at least

to do that *successfully* is to pull the bills out of circulation
immediately as the coins are released.
Our "Susie B" dollar was a failed attempt -- becuase the bill was not

I picked up an HDD made for the Atari ST by ICD. It is a shoebox form and
has space and connectors for 2 HDs. The highly proprietory HD interface by
Atari (ATASCI ?) is usually directly converted to SCSI in most newer HD adapter
interfaces for STs.
In the Atari and ICD HDs the DMA output was converted to SCSI by an ICD card
and then to MFM or DLL. via an Adaptec 4004 (MFM) or 4070(RLL) controller.
This one has an Adaptec 4070. The 1 drive present is a Miniscribe 3834P .
I understand that some MFM drives could be coded by a RLL controller if
they were fast enough, etc. I have an ST4096, which according to the specs I
have seen is an 80 meg MFM , as well as several other smaller MFM HDs.
According to a spec sheet the 4096 would work with Perstor Systems ADRT
controllers to double the storage which would seem to indicate it was of high
enough speed and quality to stand the tighter coding.. Anyone know if this is
also true with an RLL controller or what MFM drives do work with RLL ?

PET has a left arrow for that code as well. Sensible, since underscore is
available elswhere in the character set (shift-$ IIRC) but I never knew it
used to be standard ASCII. What other changes have there been? Is there
any precedent for PET using up-arrow instead of circumflex?

<whole stinking computer world to Bill Gates on a silver
Specifically it was seattle computer that needed a 16bit os
for their S100 8088 box. They literally took CPM1.4 disassembled
it and lofted it to run on 8088 and called the result Q-dos.
They had no incentive to improve it and cpm1.4 was actually
behind V2.2 (then current!).
Billy took it and modified it some say per IBM to go from the
CPM allocation scheme to FAT (Billy had used that in their
disk basics).
<For crying out loud, the first versions of UNIX ran on
<minis that didn't have any more memory space than micros.
<(OK, so they had 16 bit processors, I know. So did the

Unix had been on DEC pdp-11s for years when the Altair
rolled out. It was a $24,000 source license and even though
the PDP-11 is 16 bit the instuction set, memory managment and
disks were about 10 years ahead of the PC. Unix wanted memory
and it wanted a hard disk of some size to work well.
What si forgotten is the path to unix(linux etal) was via C
language for micros. To that Scot Guthry(Tinyc) was the
starting point for Smallc and later SmallVM. Those things were
the catalyst needed to get people interested in C (adverse to BASIC
and PASCAL) as a language. With a systems language people were
thinking about Unix (written in C). concurrent to this DRI was
working on and delivered GSS Kernal, GSS-80, and GEM which was
influential in presenting graphics to the desktop as part of the
OS. Others were doing it but as standalone apps aimed at specific
hardware. This was the early to mid 80s where the PC went from
XT to AT, DOS to desktops and integrated applications and the z80
was still giving them a hard run for the money. It wouldn't be
until the late 80s and the advent of the 386 before the battle
lines were starting to clear. In the mid to late 80s the SUN,
Apollo and DEC (others too) workstation war would extend to the
PC market via apple and the Mac and push 32bit cpus, graphics,
networking and performance.
I's more than Gates getting dos, it was opportunities and near
disasters in the industry that got us here. Even Gates saw a few
really bad years in the mid 80s when dos3.3 was really the harbinger
pointing at an end of the line with something new/better needed.
Graphics we know were not going to happen on PDP11 or most other
16bit cpus as they don't address enough space. OSs were driven by
the environment and it's tasks plus space needs.

Hi, folks.
I'm new in these parts, having been referred to the list during a quest
for some (very) old Data I/O programming equipment. Before I stray from
that subject, if anyone has any "Programming Paks" and accompanying socket
adapters, I'd appreciate hearing from them by mail. I need a number of
particular sets for 1702, 5204, and 6653 EPROMs. If'n anyone's interested,
they're for an original Intel MCS-4 (4004) development system, National
SC/MP, and Intersil 6100 (the pdp8-compatible one) respectively. I'd also
like to hear from anyone who has or is familiar with any of these machines.
After a couple of days lurking, I'm finding the endless discussion of Altair
prices and email "formats" dreary. The former was a rather badly built piece
of crap compared to the IMSAI (though we obviously have to acknowledge the
Altair's historical importance - right BEHIND the Mark 8), and the latter
has nothing to do with antique computers. I should think that the list owner
should have clamped off that discussion some time ago.
In other news,

I can't imagine why you'd want one. The big Intecolors were mildly
interesting, but the 8-track cartridge tape drive was junk of the first
order. The later Compucolor IIs (in the hacksawed portable television
case with the 5" floppy where the tuner used to be) was one of the most
unreliable hacks of the time. I serviced them circa 1980, and they were
really bad news. One of the worst excuses for a roll-yer-own switcher
I've ever seen, and nonexistent development software. Words of advice:
If you want to learn graphics, go track down an SGI Indigo - the purple
cube. They're down in the couple-of-hundred-bucks zone now, and one of
the most elegantly built machines I've touched in almost 25 years in the
biz.
On the subject of home-supers, I'd be interested as well in hearing what's
out there. We're anticipating getting our hands on a Cray YMP-EL/98 soon,
and it appears there are a number of these air-cooled boxes being dumped
in various parts of the world.
Jonathan Levine
William Donzelli <william(a)ans.net> desperately wished to know:
> > That's why we're after our first Cray,
>
> Please tell...
Not much to tell yet. It's a YMP-EL/98, the 8-cpu version of the
air-cooled "baby's first Cray" series. It's been promised to us,
but there's a certain amount of corporate bureaucracy left to
clear. Apparently we're going to be asked to vow not to sell the
machine - or cycles - to terrorists or other unsavory sorts.
Whether participating in distributed crypto challenges (like RC5)
qualifies as "unsavory" is yet to be determined.
At the moment, we know of two other machines of the same family
that are now in private hands.
More news when we've got it.
Jonathan
OK, I realize the subject line looks off topic, but it really isn't since
this deals with handling and archiving classic media. I seem to recall
someone mentioning some of the utilities such as 'putr', 'teledisk', and
various other won't work on a modern PC with a 5.25" floppy drive attached.
Am I remembering correctly? If so does anyone remember which programs are
effected?

Well, I _did_ call it that when I wrote a programme, sorry, program fom my

"noughts and crosses"
AFAICT, Nought = Zero, Naught = Nothing
Tic-Tac-Toe is a name I had met even then, but Tit-Tat-Toe I've not come

Hi! I've got a question: has anyone ever heard of a SCSI floppy drive? I
was talking to someone about one, and he said he'd never even heard of one,
and when I thought about it, I hadn't either.
Anyway, my question is about a WANG WLTC laptop that I have. It has an
internal 10 MB JVC 16pin HD (ID 0), and an external (no internal) 360k SCSI
floppy (ID 1). In the manual, it says that a 720k floppy and a 1.2 MB
floppy was also available for it. My question is will a 1.44 MB floppy work
on it? If so, where would I even be able to find one, since I've never even
seen one until I got this huge WANG. (weighs about 18 lbs, plus the floppy
is about another 18).

OK, what would you say if I told you that you could build a two input AND
gate or a two input OR gate using just two neon bulbs (in parallel), one
resistor AND NO TRANSISTORS?
Or, how about a one bit readable, writable memory circuit consisting of
one neon bulb, two resistors, and a capacitor?
How about a ring counter with no ICs, no transistors?
I put some scanned pages up on my web page so you could grab them. The

So lamp4546.gif (pages 45 and 46) is the first two pages and lamp6566.gif
is the last two pages.
The zip file is at http://www.best.com/~dcoward/lamp.zip
If you can't view .GIF files offline, then just bring up each file with
your browser. Start with http://www.best.com/~dcoward/lamp4546.gif
I'll leave the files up for at least a week.
I hope this rekindles your interest in lamp circuits.

|That too. :^) But a 7.62 NATO is a little shorter than the 7.62 Russian.
The 7.62 NATO is 7.62x51, the same as a .308 Winchester.
The 7.62 Russian rifle cartridge is slightly longer than
this (either 53 or 54 mm), but that's completely different
than the 7.62x38, which was developed for carbines.

At 100m, it's just fine. Which is what it wa sbuilt for - short

Hello, all:
I recently got a Mac HD20 hard drive, which is the floppy-based hard
drive for the 512k Mac. It requires the HD20 INIT file, which does the
following:
<insert>
The Mac 128 and 512k will need [the HD20 INIT] extension to use the HD20.
The Mac 512ke and Plus do not. Basically the 64k ROM, 400k drive Macs need
the
extension and 128k ROM, 800k drive Macs don't. The 128k ROM as well as the
HD20 INIT give the required HFS instead of MFS of the 64k ROM. In fact your
Mac512k can also use an external 800k disk drive with the HD20 INIT (and
this works out well, 400k internal, HD20 hard drive, 800k external floppy).
The early Macs can support up to 3 floppy devices (including the one
inside)."

Does anyone have this file? Thanks!

Very interesting document, Doug, and fun to read. But I think that in 1956,
a $4000 computer (Simon) could hardly be considered a home or personal
computer. Wouldn't that have been more than most people's annual salary?
I think on the price/performance scale, the Altair is the winner and still
champion; it's price was probably in reach of more hobbyists.

That too. :^) But a 7.62 NATO is a little shorter than the 7.62 Russian.
I was taught that an AK47 would chamber and fire a 7.62 NATO round, (a
bit loose, but it's fireable) but the 7.62 Russian won't fit in an SLR,
FN or M60. I doubt this is an accident.
>But find me a new gun in .308 for $99, and I'll buy it.
Got to Indonesia. We sold them the contents of the factory that made
our 7.62mm NATO/.308 SLR's
(Self Loading Rifles - Basically an FN rifle with a few refinements) You
could probably buy one dirt cheap.
I wouldn't vouch for how legal it would be. It's not a full auto
weapon, (the L1A1's we had, anyway) so it should be importable to your
country at least. There was an auto version (L2A1, IIRC) but it wasn't a
big hit.
Our Armed Forces downgraded (IMNSHO) to a locally made/modded version of
the 5.56mm F88 Steyr (Bullpup style)
They have already discovered that:-
1: If you go to ground the wrong way, you will smash it to bits (it has
a lot of plastic). Magazines and the butt are particulary vulnerable.
Magazines are transparent plastic.
2: It's not as accurate as they hoped because the scope gets beat up by
belting it around in the bush.
3: It's not as accurate as they hoped because the barrel/breech fit gets
stuffed up becaus of the brass hats insisting that the grunts have to
take the barrel off (a twist fit) when carrying out safety on the
weapon. You are supposed to pull off the barrel and squint into the
breech to make sure it's empty. This is not good for the weapon, as it
wears the lugs that latch the barrel to the receiver, eventually the
weapons accuracy (which is very good out of the box) reduces to a point
where it's only somewhat better than an AK47.
4: It's less reliable, lot's more little moving parts.
5: The round does less damage at long range than the heavier 7.62,
particularly, it doesn't penetrate anywhere near as well.
6: The troops hate it.
7: WOD's/RSM's hate it. The rifle drill movements looks like S...
"Reverse Arms" is a joke with this weapon.
8: It's capable of full auto and it weighs less than the SLR. About the
only positive statement I've heard about it, so far.
9: It doesn't have a bayonet fitting.

This is not exactly inspiring. An AK is probably the most inaccurate

A little story:
Seeing the tinkertoy computer reminds me of the mechanical "Computer" I got
for Christmas when I was about 7 years old (1961..ish). It was a long long
time ago and my memory could be a little distorted but, as I recall:
It was made primarily of plastic and was about a foot long, 6 inches high,
and 6 inches deep. This "toy" was built in horizontal layers or "planes"
where each plane was one bit in the computer. The planes could slide either
to the right or left to represent the logic states. If the plane was in the
leftmost position, it represented a "0". If the plane was in the rightmost
position, it represented a "1". I believe there were about 4 planes total.
There was a "flag" (literally a flag) attached to the left end of each
plane that provided the output. As the machine was cycled, the flags would
raise and lower with the change in states.
Along the rear of the computer there were a series of vertical wires that
pushed the planes either to the right or to the left. These wires were the
logic "gates" that drove the computer. As I recall there were about 8 of
the wires (gates) in total.
There were small projections from the rear of each plane that interacted
with the wires (gates). To program the computer you placed small sections
of a plastic soda straw, about 1" long, on some of the projections. The
straws provided the input for each of the gates. If a straw was on one of
the projections, it would interact with the wire (logical 1). If there was
no straw on the projection, the wire would not touch the projection
(logical 0).
To operate the computer, the user would move a selected plane from one
state to another. Any straws attached to the projections on that plane
would push against the wires (gates) which in turn would push against the
other planes in the machine. Some of the planes would change states, some
would not.
For each cycle of the machine, the user had to program in the next
instruction. This meant moving around the straws on the back of the
machine. Once the next instruction was loaded, the plane was slid back the
other way. I never thought about it before but, this thing actually got two
instructions per clock cycle.
Max clock speed was about .01 CPS :-)
The manual had detailed instructions for playing TIC-TAC-TOE and it
actually worked. Unfortunately, it did not provide enough other examples
so, I could never figure out how to make my own programs :-(
I'm still fascinated by mechanical computers!

No, it is not that we do not perceive any possible problems. I at least
believe that there will be problems. But I don't believe there will be
major ones. And I certainly don't believe that they will happen all
suddenly on 1/1/00.

Possible. And may affect telephones. But water, gas and electricity
suppliers won't have the staff to go out and cut everyone off, since this
has to be done physically at the premises. Besides, such a huge number of
disconnections will be noticed and the cause identified.

Are you sure this is legal? A couple of years ago the National Savings
Bank (as it was in the UK) were saying that they had accounts that had been
inactive for over eighty (yes, 80) years with a few shillings in but they
couldn't close them because they couldn't trace the owners or their heirs.
(BTW Nat Savings never paid interest on balances less than a pound, so a
few shillings 80 years ago is still a few * 5p today)
AFAIK there is nothing in any contract I take out with a bank that says
that if I deposit money and leave it there for over 2 years they are
entitled to it. I come back 10 or 20 years later expecting to retrieve my
savings. Yes, I did this with my German bank account in 1995 having not
touched it since (I think) 1985. It was still there and I could still draw
money out when on holiday in Germany.
Yes, empty accounts may well vanish, and rightly so!

This has _already happened_ and will be addressed long before 2000. IIRC a
chain of supermarkets in the UK was asked by a tinned (canned) food
supplier why they were suddenly ordering three times the usual amount of
tomatoes. It turned out that the warehouse was accepting tinned tomatoes
each day; overnight the stock check found that they were out of date ("best
before end feb 00" or something) and ditched them, and the following day
more were ordered.
It is not something that suddenly happens in 2000.

May happen. But the first manifestations of the bug will have turned up
already - temporary contracts that expire in 2 or 3 years for example. Our
accounting, job control etc. system uses 2 digit dates. Last year (or the
year before - I forget) a lot of work was done on our system and a 2 digit
date is now assumed to lie between 1950 and 2049.

As Tony and others have pointed out, this will probably occur. But it is
relatively easy to override manually until sorted out.

Credit card companies - I forget who told this one from personal experience
- hit the bug a year ago with cards that _expired_ in 00. This made them
do all the necessary work then. While I concede that it is possible that
there may be a few bugs left in (spurious late payment penalties for
example), I doubt that accounts will disappear (and who will care? I'm not
going to fuss if a lot of money I owe is forgotten about ;-) ). I know
this is another "assumption" - that having hit the one bug they did all the
work to cure the others - but I think the evidence points that way.
Damn! This discussion is way off topic and I wasn't going to join in.
Oh well, I've typed it now.

Oh, a spirit duplicator! I've been wondering for ages what a Mimeograph
was!
In the UK such machines were generally known by brand names. For small
runs - a couple of hundred copies - one used a Banda machine (2-part sheets
on which typing or writing transferred a waxy, usually purple ink to the
back of the top sheet. The duplicating machine put solvent on this so it
would transfer the ink to the paper.
For longer runs one used a Gestettner (I don't know how to spell it,
either) machine. Cut stencils by typing with the ribbon disabled in your
typewriter, or drawing with a special stylus.
I heard of electronic stencil cutters that would transfer a plain paper
image to a Gestettner stencil, but I never saw one.

As a matter of fact, mimeograph/ditto/Spiritusumdrucker machines
provided me with one of my favorite examples of "antique" technology's
applicability. My wife was teaching at a high school in the early 1990's
that had a way over-subscribed photocopier and an idle mimeograph machine.
She made handouts on our Mac Plus using WriteNow and SuperPaint (both
fantastic programs). She then printed them onto mimeograph masters using
our ImageWriter 1, an *impact* (dot-matrix) printer, at home the night
before class. She'd take the master to school in the morning, hook it up
to the mimeograph machine, and crank out 250 copies as fast as she could
turn the crank - then stroll to class past the line of frantic teachers
awaiting their turn on the photocopier, having saved the school appx. $10
in copying costs.
She could also save and modify files and print new masters at her
convenience. No need to carefully retype or coddle a master for a whole
year for next year's class, or try to stretch a dying master for 30 more
prints. It was a great system.
BTW, she later convinced me to *give away* the Imagewriter in favor
of a Stylewriter (inkjet) we recieved as a gift, just prior to moving to
Texas. Not one of my better decisions. Ah well.

Yup. With a great big hammer and a nearby dumpster. If I want warts,
fun, and interesting, I'll spend my time on the MCS-4 or even one of my
old DG Novas. They had their strengths and their weaknesses, but they
were both well-built and historically significant. A badly-designed
machine was a waste of time the first time around - you insult your own
short lifespan by wasting yet more. If you don't agree with me, I'll
be happy to send you a box of assorted unreliable S-100 DRAM boards that
will keep you busy well into your retirement.
As for fun vs. usable, who the hell says you should have to choose? Why
not have both? That's why we're after our first Cray, why we maintain the
NetBSD Build Lab (a single location in which we're trying to assemble one
example of each machine supported). Normally I couldn't give half a shit
for Amigas, but it's fun to rackmount one and help get unix running on it.
Maybe that's the primary philosophical divergence here: I consider few
obsolete machines to be inherently interesting, when there are so many
others that are merely _thought_ to be obsolete but are still utterly
useful given a current, robust OS.

Well, this is just silly. How much more luck have you had getting parts
for that Compucolor? SGIs are just like anything else - if you've got
enough bits you can maintain them yourself. And I'll tell you one thing
for sure: Gathering enough spares to do the support is easy, seeing as
how there aren't (yet) any collector scum driving the prices of Indigos
to 20 times their original price.

Speaking of the Horizon, does anyone know anything about a New

There were a number of mostly-accurate replies to this yesterday. Seeing
as how I wrote the FAQ, I'd like to present the mostly-definitive reply.
First, this is a 68020-based, Multibus machine. Nothing at all in common
with the later MIPS systems.
According to William Donzelli <william(a)ans.net>:

IRIX 3.6 was the last OS distributed. There's some incomplete 3.7 stuff
kicking around, but probably not of interest to most. To my knowledge,
no open-source unix has ever been ported to one. X is not supported,
though TCP/IP is, so you can get it on the network, but it's going to take
you a bit of work to make it useful, like compiling bind, as they predated
DNS. Your server will offer you a delightful choice of drives: ST506,
ESDI, or SMD. No SCSI.
Note that when SGI put out the first 4D (MIPS R2K/R3K) machines, they called
the OS IRIX 3.something as well, just to create confusion.

IMnot-so-HO, that's too much money. Stuff of that vintage should be GIVEN
to you for nothing. Pay 'em $90 only if they'll deliver.

Yes, they all have ethernet. Want a unix box? If so, they're worth grabbing.
Monitors are fixed-sync RGB, and probably not useful on anything else you
have or might get.
As it happens, there's another (non-list) chap for whom I've been getting
my 3130 running again (a bad video board, then a blown /etc/passwd...) in
order to generate a boot/install tape. I'd be much more enthusiastic about
doing it if there were a few other people on the list who need them as well,
so I can do a bunch at one time.

Its an interesting thought, and I know from personal experience that
a set of Kenwood Twins operating at 100Watts about 4 ft from a TRS80

Thats a dumb question.
The situation is that an IDE drive has it's controller on board the drive
and it is proprietary. The purpose of the IDE "controller" card is only to

Bruce,
FOLD THE LINES! MY screen is not 200 chars wide and I really hate
horozontal scrolling!
< Here's what I remember about Horizons: S100 bus, CP/M for an OS,
built pre
<
The native OS was NS* DOS not cp/m though there were several vendors of
CPM configured for horizon.
Generally they were z80/4mhz cpucard, MDS hard sector disk of 80k for the
older single density controller or up to 800k for the later DD controller.
Ram minimum for running NS*dos was 16k orged at 2000h while cpm required
20k(minimum and 56k max due to memory mapped disk controller). The s100
backplane was not IEEE696 complient but pretty close considering its design
window was many years earlier. The mackplane also carried the logic for two
serial ports, parallel port, interrupt logic and a heartbeat timer.
A minimum system could then be the box and three cards and the most often
cards added were ram. Theses systems use an external terminal though I'd
set mine up with a VDM-1 video card and a encoded parallel keyboard.
Another OS that ran on the NS* was UCSD PASCAL P-system. The basic system
for that required 48k ram and two floppy disks minimum and three(or four if
it was the DD version) were more useable.

There used to be (probably still are) X.25 public data networks.
"Public" means "not private" -- effectively, the network owner sells
connections and bandwidth to paying external customers, not just to
users within the owner's company. You as a customer would pay your
money, and the network owner would deal with details like telco so
that you effectively get RS-232 synchronous serial port(s) that want
to see and hand out X.25 packets at your various locations, and X.25
network addresses corresponding to those ports. Or maybe you would
pay for the telco stuff and an access charge to the network provider,
and get a port on the network provider's X.25 packet switch.
This might be of use to you if you had a need for computer/computer or
computer/terminal communication between distant locations. Host
computers (minicomputers and larger) often had X.25 network interfaces
available as an option, and software that supported
computer-to-computer communications and/or terminal-to-computer
communications over it. Terminals didn't, but you could get devices
called PADs (Port Access Devices? I can't remember) that had
connections for terminals, an X.25 connection for the network, and
could either act something like a multiplexer, running all the
terminal sessions over a permanent virtual circuit (PVC) to a host's
address, or like a terminal server, using switched virtual circuits
(SVCs) to connect to any host address on the network.
Or you might just have a host and a casual need for connectivity from
terminals in remote locations, e.g. you've got some database and you
sell access to it. So rather than installing a modem rack, you get a
connection to Telenet and tell your customers that they need to dial
in to their local Telenet access number (which is really a
Telenet-owned modem pool with something-like-PADs behind it) with a
terminal and modem and connect to such-and-such address.
Either way, the X.25 public data network solution could be cheaper
than installing point-to-point telco data lines between your hosts and
terminals, and the X.25 network provider could offer internal
redundant routing that might be prohibitively expensive for you to
implement on your own.
Now, that said, X.25 networks do not need to be public. If you have
the wherewithal, you can build your very own X.25 network out of the
same sorts of hardware that the public data network providers use.
I guess the Iraqi government could have one or several.
And I remember a data center that, in the late 1980s, got fed up with
its computer-to-computer communications being done entirely of
point-to-point links between computers (with a protocol that wasn't
smart enough to forward messages -- if you wanted to go from host A to
host C, and the only connection was through B, you had to log on to B
>from A then C from B) and bought a small Dynapac X.25 switch to sit
between the computers.
X.25 can also be used to transport other protocols' datagrams,
e.g. IP. In fact the US Defense Data Network was IP-over-X.25 and may
still be for all I know. I think this sort of thing is either
incompatible with or distinct from using X.25 to carry host/terminal
traffic (in much the same way that e.g. rlogin and telnet are distinct
-- they both run over TCP but use different protocols, and different
ports so TCP can multiplex them), so you can't just dial into a PAD
and telnet to a host doing IP over X.25, unless the PAD also does telnet
and IP over X.25.

course, that would mean never responding... If life ain't interesting, it
probably ain't worth living.)

Anyone know where I can get or have a spare copy of _Fire in the Valley_?
Someone was going to send me one a while back but never did.

I powered my micro PDP-11 up for the first time, today. Here's what
happens (please keep in mind I have no manuals or familiarity with the
PDP-11):
Memory Test
Message: "Booting from DU0"
Message: "Device XK0: does not interrupt - device disabled"
Message: "RSTS v8.0-07 Micro/RSTS (DU0) INIT v8.0-07"
"Option" prompt.
At the "Option" promt, I typed "Help", bringing up a list of options.
{To actually begin "using" the computer, am I correct in assuming I want
to select the option "Start" to start timesharing?}
At the "Option" prompt, I typed "Start".
Here's what the screen looks like, afterwards:
Option: START
Disk is being rebuilt - wait...
DU0 error UDASA P.OPCD P.STS P.BCNT P.BUFF P.BUF2
P.LBN
000000 000242 020006 000000 044000 000000

Unrecoverable disk error on DU0
PC=121232 PS=030341 OV=000022 M5=001600 M6=003242 SP=041274

Fatal RSTS/E system initialization error!
Option:
-------End.
Now to me, this sounds like a bad hard drive, but I'm not at all familiar
with this. If somebody could offer their opinion as to what's wrong here
(and what to do about it) I'd be most appreciative.
Thanks!

Close. The Horizon was definitely one of the better-built and more
reliable S100 boxes of the time. 10 slots (I think), and a little
unusual in that the serial and parallel I/O were built into the
motherboard. Most had a wood case.
(I once had to replicate all that stuff on a wirewrap board for a
client who needed more than 10 card slots and had to migrate to a
Cromemco Z2 chassis while maintaining I/O compatibility. I also
discovered with that system that their hard disk - a 14" 20(?)meg
Century drive - suffered from serious read/write problems due to
ground loops. Annoying but solvable. I digress...)
CP/M was available, but not the stock OS. North Star (originally Kentucky
Fried Computers - swear to god) designed their own unique floppy controller
(it was their entry into the S100 market) and had a proprietary OS to go
with it. The controller was a full S100 board to run the 5" drives alone,
and the weird and difficult thing was that they used HARD sectored floppies,
10 sectors per track (not to be confused with the 16 sector floppies used by
Micropolis).

Hi. I recently got an Apple II+. OK, it's not the most exciting
system in the world, but very cool in it's own respect. It's totally
FULL of all kinds of add-in cards (including a AD/DA converter),
and has 64K RAM. (48K+16K Pocket Rocket), etc. So basically,
it's a nice II+, but more important to me is the add on cards, which
probably hold tons of interesting secrets. There's a problem.
MACHINE WILL NOT BOOT. I can turn it on, floppy spins, but I
won't get a display. None at all. One possible reason is that the
local power is 110v, 50hz, not 60, but the IIc works fine. It was
also shipped here air freight, but once again, other computers
work, but that doesn't prove anything. Ideas? Suggestions?

I'm sure someone here has heard of a NorthStar Dimension. Was it a PC
compatible system?
