NO!!!! I just tried to run a SYSGEN on my RT-11 system, and I seem to have
lost the filesystem when it started to rebuild the system. I'm able to
boot to another partition (gotta love that WQESD controller), and I get the
following results:
.dir du2: <-DU2: is my main RT-11 disk
?DIR-F-Invalid directory
.
Please tell me there is a way to recover (unfortuanlty I doubt there is).
I wasn't smart enough to make backups and everything I've been working on
was on that partition.
I'm seriously bummed. However, I finally got smart and made a bootable
TK-50 so if need be I can load RT-11 without to much difficulty (other than
having to type in the bootstrap by hand).
First I can't get TCP/IP to work, and now this.... :^( Looks like once I
get everything back together I'll be starting on that from scratch, which
might be good.

Two Xerox 800 system units with dual tape drives and associated
typewriter/terminals are now at a local thrift. They appear to be large
(each of the them I guess would top 100lbs) word processing systems with
many(?) logged years. Do these have any redeeming value to anyone (expect
*serious* dents in your 1)wallet/purse for shipping, and 2)living/storage
space for size) ?
Or am I missing something I should nab? ;)

This may be OT, but the computer is a bit unique in its own way (in the fact that there's only two that I've ever heard of/know exist - the one that I have and the one that the person I got it off of still has)
It's an IBM 9075 Laptop PC radio. One of the neat things about it is its display. Looking at it, it's reflective (silver), but when it's turned on, it's backlit, and after it boots, the backlight can be turned off under bright light.
Anyone have any info on this thing? I just picked on up, and got it to "boot" by connecting a Mac power supply to the battery terminals (7.5v). It came up with the backlight, then did the 640k memory test gave a CMOS battery date error, then booted to drive D, which is a ROM drive. I took it apart, and it has no HD or floppy, an 80186 processor, a modem, and a "Motorola Cellular Packet Radio".
First thing: where could I find a power supply for it? The connector is an odd round 4-pin plug.
Next: Where can I find IC cards? It has what looks like a PCMCIA slot, but a PC card won't fit, and it is apparently for IC RAM (ROM?) cards.
Last: How does the Packet Radio thing work? Where could I find drivers, or an antenna or something for it? Or should I contact Motorola?
The computer was apparently used by a Sears Service tech, but that's all I can figure out so far.

I realize this is way OT, but hope someone can give me some advice.
I am trying to install an ATX MB in an ATX case. All jumpers have been set
by the book. There is a switch on the power supply, and another on the
front of the case. This latter is a momentary contact type.
With the MB outside the case on a wooden surface and nothing connected
except the power supply plug and the front push button, all that I get is a
twitch from the cpu cooling fan, on only the first push, after that nothing
until it sets for a while.
Since this is the first time I have tangled with an ATX I have no spare
parts to substitute, so any help on how this power supply is supposed to
operate would be much appreciated.

Actually, I saw a prototype laserdisk player in a museum somewhere
(I think it was in the LA Museum of Science , but it was a long time
ago) that had the following arrangement: The HeNe laser tube was
bolted down, along with some optics, and a spinning platter/servo motor
mounted on a carriage. The *PLATTER* moved during seeks! It was
really quite bizarre to watch.
They used a *BIG* servo motor to move the carriage, if memory serves.

Don't know if anyone can help on this, but wanted to post this query to the
kind folks here...
I have a PDP-8E system, but it appears that the previous owner got many of
the parts from different sources. The system has a paper tape reader/punch,
but it's for a PDP-11 (PC05) not for a PDP-8 (PC04). I have some information
that shows how to convert a PC05 into a PC04 so I can use it with the 8E,
but I would prefer to not have to do the conversion unless absolutely
necessary (I don't like to mess with historical accuracy if at all
possible).
So - does anyone have a working PC04 paper tape reader/punch that they would
want to trade for a working PC05 paper tape reader/punch?
Thanks mucho!

I have a Honeywell DPS 6, nice computer, really, but I've got a problem.
There is one of these weird fixed disk/removable cartridge drives (yes
that is a fixed disk and removable cartridge in one) that has a broken
belt that runs between the drive spindle and the motor. It is this weird
small v-belt.
There is also this large hard drive in another cabinet that connects to
the thing using DB37 connectors, IIRC. I'm not sure of how to connect it
to the computer, nor do I have the cables.
I do know the box runs GCOS6, which from what I hear is a cross between
GCOS and Unix. Hooray for me, if I can get it working. Although it is
supposedly not y2k compliant, but I think that is just a ploy so Bull can
get you to spend money on an upgrade. :-)
Any hints or tips or free belts for that thing, or places to get belts for
that thing, would be appreciated. Any help on running GCOS6 would be
nice, as in how do I get the super user account on it? How do I add
users, etc.
On a different note, I may start a list for buying and selling old
computer stuff, everything but PCs, pretty soon, if interest is good
enough. Please email me personally at "enigma(a)intop.net" if you would
like to see something like that.

I simply find bit-serial AWFUL - so much time wasted !!! Anything

a good solution for a LONG word, like 30-60 bit, doing floating point,

This doesn't sound out of line. The CPU of the PDP8/e on my desk is 3
quad cards of TTL, mostly simple gates. Perhapes 250chips total. OK, some
of them are more complex (like full adder circuits), but there's nothing

If you're going to allow anything in the TTL data book, then you can
trivially make a CPU in 200 chips. You have to cheat slightly (74181
ALUs, small PROMs, etc), but it can be done. It has been done - many times.

The big difference is in the basic AND-OR-INVERT tube gate used: only
one half tube (the INVERT, one triode section out of a dual triode
tube) is used,
but a lot of diodes doing the ANDs and ORs,
so that one tube section is equivalent to MORE than a standard SSI 74xx
IC.
Typically, I would say one AND-OR-INVERT, i.e. one tube section
plus associated diodes and resistors is equivalent
to about one entire 74xx package, so one tube is equivalent to about
two
packages, on the average.

I've got some bits of a Nixdorf something or other. Basically it's the

OK, I'm back to trying to get Alan Baldwin's TCP/IP package running on
RT-11. I've gone over the install procedure and am sure I'm doing it
right. Tonite I was trying for both TSX+ and the RT-11 XM monitor using
the EQ driver, and also the NQ driver that came with RT-11 for the XM
monitor.
I know the ethernet board is good as I'm able to use it under RSX-11M for
DECnet.
Howver, I'm getting the following error when I try to use FTP to connect to
one of my other systems on my network.
.ftpsb 192.168.1.41
FTPSB-11 V02.24 1-Nov-1998
Board initialization failed!. Error code=11
netinit() failed
.
Can anyone translate this and tell me what I'm doing? Has anyone here
managed to successfully install the software?
The other problem is that while the instructions say that the EQ drivers
included will work on a system running the SJ or FB monitors, I can't get
the driver to load. Yes, I realize it's not normal for the SJ/FB monitors
to be able to use a EQ driver.

Hi, group.
I'm going to be putting up my annual exhibit at the local library and I need some
help with my facts so I don't screw anything up.
I have two display cases to work with. One will be tracing the development of
the portable pc, and will include the usual Compaq Sewing Machine, a Compaq
III, and a Compaq LTE286; a Kaypro II, an Osborne, a Mac Portable (non-
backlit), IBM Convertible, and a Tandy M200 and Pocket Computer. (I'm really
trying to get an M100, but all the reporters I know who still use them would
rather have their fingers removed first before they'd give 'em up.......)
Can anyone give me the original release dates and some tech specs on the
200 and the Pocket? The 200 has the parallel printer card, the external floppy
drive, all the books, and several floppies with stuff on them. The Pocket is the
original model, and has software, all the docs, the original boxes, the original
carrying case, RS-232 interface and the neat little color plotter/printer.
Any info, anecdotes, whatever would be greatly appreciated and acknowledged
in the display.
Thanks.

I have no clue other than the vague chart on the back. It looks like a 150
drive will read write format with a * for reduced performance a 90 meg cart.
It does not say anything about using 150m media in a 90m drive. This makes
me think the media will fit but will have to be formatted. To be sure I
would contact IOmega.
The only Bernoulli drive I have ever used was a just released 20m (I think)

Silicon photodiode predated the transistor. You would need that or
a photo tube to be remotely fastenough as the selenium or CdS is far to
slow.
In the early 50s when the tube was king germanium and silicon diodes
were reality and very common in computer and other uses. The problem
is the LASER postdates transistors! The optical light source would have
to be a collminated point source. Memory is easy, delay lines really big
ones!
BACK OT... A vacuum tube computer using germanium diodes and tubes in
under 400 of them would eb hard even with a 12bit word. It takes a minimum
of 1/2 a duo triode to make an inverter and a FF needs at least one
dual triode tube and a few diodes for steering. AND and OR gates using
diodes are trivial but a 1 bit full adder would eat several tubes and lots
of diodes. a full function ALU like '181 using tubes would easily eat
about 50-100 of them for 4bits though some logic economies could gotten by
using pulse coupled logic. Register and ALU are the primary consumers of
transistors/ICs/Tubes with gating of signals being a next level user.

It's character 0xA3 (decimal 163, octal 243) in ISO Latin 1, and most
systems that don't have a special key for it map it to the "#" key. On
older systems, quite often the drivers replace the "#" character with the
pound symbol, but some replace the "$".

Not even close. There is no shared history either as noth evolved from the
larger systems each made. The registers in the 9900 were very general in
use and symetrical in adressing modes. The 1802 the registers were not
general. They were mostly for pointers, stacks, and maybe storage. The 1802
had the ability to use any register as the program counter (via sep and
interrupts). The TI9900 the PC is one of the few hardware registers. The
1802 is a primary accumulator machine and the 9900 is anything but as all
registers are the target for the result.
<Hmm, 1802's were used in satellites, right? Do satellite apps need lots

They would like that but the 1802 was used as it was available as
RAD hard and CMOS (low power!). The latter is more important as 10mW is
nothing compared the the ~600mW of the 9900 cpu never minding clock
generation (ttl 4 phase clock generator) support.

Hi all,
I have recently joined the list, not yet contributed too much, but enjoyed
reading quite a bit.
My personal preference is older stuff - if it contains integrated circuits,
I am not too much interested (with the possible exception of a Cray-1).
I did not succeed in finding any serious equipment in vacuum-tube technology.
Therefore, I decided to design and build a complete computer with
vacuum-tube technology from scratch. A short description of the project is
enclosed,
for those of you who might be interested. The attachment is best viewed with
some straight ASCII editor, like the MS-Editor.
Thanks to Hans Franke for a reading of a draft version and constructive
comments.
BTW, I am located in Munich, Germany.

You could subscribe from that address, and then tell the list processor
to postpone sending you anything there, and never cancel the postpone
order. I *think* you could still post from that address. Of course,
the list processor may eventually explode, holding back all that postponed
mail... (Would it actually hold copies of all that, or just drop it?)

Cheers,

Is anyone on the List, in the Southern California area, interested in a
CDC 9766 350MP top loader, with three disk packs? This unit was attached
to the Prime system I got recently, but is *not* going to be used with
the way I have the Prime configured.
I have gotten an offer of $100, but I have to deliver the damn thing,
and it's 600lbs.
I would like to sell this unit for a little more than $100, or I would
consider donating it to a worthy situation, ie. needed for a systems
restoration, or to supply parts made of Unobtanium.

Very good!
Now Tony, you have the responsibility to completely photograph this machine
and try to find a correct keyboard and PSU. Some of us will appreciate
seeing the photos and comments to learn (or relive!) this interesting
machine. I know I'll keep an eye cocked for the parts to help get this
machine restored. And to think this machine was only about 3 or 4 hours
drive from here!
Good luck with it :)

A Guide to Collecting Computers and Computer Collectibles:
History, Practice, and Technique
1st Edition
----------------------------------------------------------
This book is about the hobby of collecting computers and
things related to computers. It's about the hobby in
general for novices who are interested starting, building
and maintaining a collection.
It's also for veteran collectors as an attempt to bring
us and a few of our stories, experience, and advice
together.
This book wouldn't be complete without also paying tribute
to the pioneers in the field and so it includes coverage
of many wonderful private collections and related
"how I got started" stories.
This book is simply the best resource you'll find to help
you get started and flourish as a computer collector.
This book has nine chapters, plus a section on resources.
By reading this book you'll discover what to collect, how
to collect, and how to manage your collection, including
how to clean and store computers. Each chapter opens with
an Anecdote and ends with an Profile.
A Profile tells you about another collector - why or how
they started collecting and a description of their
collection. I am humbled by their acceptance to
participate in this endeavour. You'll know what I mean
after you read about them.
Anecdotes are mostly from my own experiences. They no
doubt pale in light of your own. Each Anecdote is a brief
story about the trials, tribulations and thrills of collecting.
I have not tried to make this a pricing guide, although
the topic of Appraising is covered, and there isn't any
photographs.
I have tried to make this book:
* a practical reference;
* an entertaining piece of popular history;
* an encouragement.

Greetings. There was a two month gap in my participation on the List until
recently. Somehow, and no one has yet explained it, my subscription was
removed (this happened again two weeks ago). Unfortunately, I missed a brief
discussion of the book I wrote - it was reviewed in Dr. Dobb's Journal. Had
I known, I would have contributed. To make matters even worse, the
Classiccmp archive maintained by Kevan Heydon (many thanks man), also
suffered from a technical glitch and needed to be restored. Now I've finally
read the thread and please accept two observations and two invitations.
Observation #1 - the books' identity crisis
The book is a guide about the hobby of collecting computers and not a
traditional collector's price guide. In a perfect world one would first read
the guide to collecting and then want to read a collector's guide - the
first guide stokes and refines the interest while the second guide assists
in ensuring a collection is complete and in determining how much to buy and
sell for.
Observation #2 - the book's other identity crisis
The book is for both seasoned collectors and beginners. It is not JUST a
book for anyone who thinks collecting computers could be neat. Sure the
guide will, by design help the novice, but it's equal strength is in helping
the existing collector by affirming our practices and techniques and, by all
means, sharing some of the practice and techniques the veteran collector
might not know about. We should all be open to accepting our knowledge-gaps.
In fact, a computer collector might not consider their collection complete
without a copy of the first-ever book about collecting computers.
Invitation #1 - answering questions about profilees
I've been asked why some collectors were omitted and even why some were
included. I expected such questions. As an author with a deadline and goal
in mind I invited collectors who exemplified the experienced collector, the
new collector, the big collector, the small collector, the international
collector, etc trying to show how collecting is the same all over the world
- same passions and problems. These collectors would/could also be
role-models. The book might have included more profiles if the collectors
had responded on a timely basis and with answers to the questions I asked.
One collector didn't remember the dates and circumstances surrounding his
most important acquisitions so I rejected the story because it was
incomplete (even after several attempts to help improve its accuracy).
Please send your questions about the book to me directly.
Invitation #2 - my first attempt at building a web site
Please take a moment to visit my site. See the orphan 360/22 mainframe
(orphan because it was announced the same year the 370 series was!) and a
few other systems that aren't that popular.
Thank you. Happy collecting.

Well well, people throw out the darndest things..
I found a copy of a book by someone named Peter Norton. Looks to me like it
may have been his first book. Called 'inside the IBM PC'.
His 2 test systems for developing the book were:
IBM/PC with 64K standard memory and 512K on a jumbo memory board that
he bought as a lark. The jumbo board is populated with 64K chips.
he mentions tha this board does provide astonishing improvement in
his Pascal programs.. (Duh!). Monochrome monitor.
Second system has a Amdek color II monitor, 128K of true blue IBM memory,
twin Tandon TM 100-2 diskette drives, and the standard color graphics
adapter.
Oh yeah, he mentions that he uses teh Jumbo card to simulate a 360K
virtual diskette drive ;)
He disassembles roms, disusses bios calls, and explains how the cassette
tape interface works, among other things. Personally, I think this
guy could go far...

Hi Gang:
I learned this morning of two DEC 11/70s that are available for free in
Vancouver, BC. Taker will have to pickup. These are large systems that will
need a few strong people to get into the back of a truck.
Both were operational when last fired up 3 years ago, and have been in dry
storage and covered in plastic since.
Included are disk drives, 2 tape drives, consoles, and all documentation
including, it appears, print sets. Tons of software as well, including a
few compilers. I haven't seen them yet but will try to do so if there's
much interest.
My basement is far too full already to take one myself, :-(
There's also a Microvax II in a BA23 case (that's the bar-fridge size model
on casters).
I live in Vancouver and will be able to assist in the removal and loading.
Please contact me via email or at the office (604) 215-4812 for more info.

I finally had a chance to get out and hit a few thrifts again. I was
chained in a studio working on an anime, but I'm free again.
Anyway, I found a Xebec Sider harddrive. Was this for the Apple //?
Something was loose inside so I checked and found a small
rectangle filled with some ceramic like stuff and a wire sticking out
of each end inside of the PSU. Can't seem to see anywhere in the
power supply where this thing may have come from but also can't
see how it could have gotten inside if it didn't belong. Not even sure
what it is. Any ideas anyone? Also would like any info on the
drive type, size interface, etc. It is a model 9710H. Looks like I
can pull the drive from the case and hook up a different PSU.
On another note, anyone tell me anything about a handheld unit, I
think it was an LK-3000 or some such, I'll have to go back and
check. The guy wants $50 for it and also has a Tandy Pocket
Computer for $40 I'm thinking of picking up.
Other things I grabbed:
Odyssey2 in box
Coleco Adam in box (damn big box for a home console system)
Atari 1040STf (may sell/trade this as I have one and an STfm too)
Couple of Apple 5.25" drives
Misc software and books
For those of you who were interested in the Mattel Aquarius Data
Recorders, after two months of no replies to my query on where to
drop off the money and pick up the recorders, I have finally given up
on them. They said they accepted my offer but then they just fell
silent. Guess they found someone else with a better offer.

An ideal class of problems is Monte-Carlo simulation. You distribute
identical programs to the machines, and different random-number seeds. Then
each machine computes any desired amount of time (1 hour ? 1 day ?
1 week ? 1 year ?) without ANY communication. At the end each machine
communicates just one or a few numbers to central, which takes the
averages - that's the result. I had Cray machines working at theoretical
max performance (all processors) that way.

Owww.. Don't you get a face full of flumes from the solder?
And because of the small parallax (eyes to mouth), don't you
have a depth perception problem here? As well as a stiff neck?
(Not to mention sucking on that piece of lead in your mouth.)
Try this. Holding the iron in your right hand, take about
8" of solder and wrap it a couple of turns around the tip of
your little finger (right hand) with about 6" extending toward
the tip of iron. You can control the solder by moving your little
finger back and forth. Sure, you will wind up with a few short
pieces of solder, but you can use them on jobs that don't take so
much gymnastics.

<What are WP and PC w.r.t the 9995? I'm reading the memory map and I don't

OK,
WP... workspace pointer. back when the 9900 was new registers (memory)
really ate up chip space and TI had an archetecture in the 990 minicomputer
where register were in memory instead of in the CPU. So the WP is a pointer
that points to a block of 16 locations in ram that are addressed in
instructions as R0 through R15.
PC is PC just like the 6502. It's the instruction counter.
BLWP is an instruction that does several things.
It branches to a specified address.
It saves the WP and PC in the R14 and R15 of the new
workspace.
It then resumes at the newly specified PC.
Obviously it nees two parameters a new WP and PC. They are specified by
varios means (addressing modes and registers). Think of it as something
like a 6502 call and Push combined though it's more powerful.

Hmmm, I suppose that depends on your point of view. With the
"collector's guide" for pocket calcs coming out in '97, and the
message traffic of stuff for sale on some of the web sites,
seems to me there is quite a lot of interest in pocket calcs and
prices are going up very quickly. I've been active in this stuff
now for about a year & a half. I see lots of new names bidding
on calc stuff each month, FWIW.
>That doesn't mean things are cheap, or that you can always find what you
>want. But the list I'm on has very light traffic and a very high S/N ratio.
Very true, I'm not sure why there isn't much traffic on the lists.
I know quite a few folks who collect calcs, and there seems to be
a lot of private e-mail exchanged, but not nearly the volume of postings
as on this list, for instance.
>The Web sites I've seen are informative and rather "gentlemanly". Use of
>eBay doesn't seem to be encouraged.
Seems like the trend is towards eBay, however - on the web sites
that provide calculator classifieds it seems like more & more of
the calcs for sale are listed on eBay rather than at a fixed price.

Well, another calc-related URL is for my site:
Calculator History & Technology Archive
http://aknight.home.mindspring.com/calc.htm
I have a bunch more calculator links on my site, and am a part of
the Web ring that Andrew set up.
FWIW, I'd set up an "egroups" list for calculator discussions
and you'll see a link to that from my web site, but there has
been no traffic and due to the difficulty of using egroups I
may discontinue it altogether.
On my site right now I'm leaning more towards coverage of early desktop
calculators - they seem to have more in common with classic computers
(particularly micros) than do the pocket calcs, and plan to expand
coverage to certain early computer stuff as I can. One of these
day's I'll show ya'll the insides of my H9 terminal, man what a lot
of ICs. Maybe even my homebrew pre-PC 8086 machine...

A man was to be married and his friends threw him a stag party.
As usual there was much drinking and merriment. As the evening
wore on, the man was dancing nude and and hit his erect penis on
the fireplace, knocking himself out.
Concerned, his friends took him to the hospital. Following an
examination, the emergency room physician told them that their
friend's condition was stable, that he was bruised and sore, that
the medical term for his injury was complicated but in layman
terms, "He had broken his prick". They shouldn't worry though,
because he had supported the injured part with 4 tongue
depressors neatly bound with tape.
The next day, the wedding was flawless and the bride was unaware
of any problems. In their honeymoon suite, the bride was
spread-eagled on the bed when her husband emerged from the
bathroom and she said, "Come and get it , Honey, it's all yours.
I'm untouched by any other, this is pure virgin wool".
The groom smiled as he dropped his pajamas as he said to her,
"Check this out, Babe, still in the crate".
______________________________________
A guy was at the supermarket and after buying a few things he
began to queue up in this really long line for the checkout.
After about 15 minutes in the line he reached the checkout girl
and just at that moment he remembered that he needed some
condoms.
Not wanting to line up again he said to the girl "Oh I meant to
buy some condoms but forgot"
"Do you know what size you are ?" she asked.
"No".
"OK drop your pants and I'll tell you what size you are".
The guy then, not being the shy type, drops his trousers and the
girl has a feel with her hand and then says in the microphone "1
packet of large condoms to aisle 3 please", he pulls up his
trousers, the condoms are brought to him and he pays his bill and
goes on his way.
Another male customer sees this and thinks he'd like to have this
nice girl fondling his prick and so says the same thing to the
girl. A similar course of events takes place, only this time
after having a feel she says "One packet of medium sized condoms
to aisle 3 please", the condoms are then brought to him and he
pays the bill and goes on his way.
Also watching this course of events was a rather excitable 15
year old boy who then decides to queue up and try the same
routine.
"I'd like to buy some condoms please, but I forgot" he says.
"Do you know what size you are?"
"No."
"OK, I'll check. Whoops, mop and bucket to aisle 3 please!"
_______________________________________
A man was sitting at a bar enjoying an after-work drink when an
exceptionally gorgeous and sexy young woman entered. She was so
striking that the man could not take his eyes off her.
The young woman noticed his overly-attentive stare and walked
directly toward him. Before he could offer his apologies for
being so rude, the young woman said to him, "I'll do anything,
absolutely anything, that you want me to do, no matter how kinky,
for £100 on one condition."
Flabbergasted, the man asked what the condition was. The young
woman replied, "You have to tell me what you want me to do in
just three words."
He quickly pulled his wallet from his pocket and slowly counted
out five £20 notes, which he pressed into the young woman's hand.
He looked into her eyes and slowly, meaningfully said...
"Paint my house."
______________________________________
A man went into a chemists looking for condoms. Unfortunately he
didn't know what size to get. The pharmacist asks him, 'Would you
like to find what size you are, Sir?'
The guy agrees and the pharmacist leads him into a room with a
board. The board has many differently-sized holes in it. The
pharmacist leaves, allowing the guy some privacy to match up his
dick with the right hole.
Three hours have gone by and the pharmacist wonders what is
taking so long. So, he knocks on the door and sees if the guy is
alright. The guy says, "Forget the condoms, I think I'll take the
board."

The guy below seems to have a bunch of old PC parts he was
going to dump. They're not "classic" in mine or the list's terms but
I know some of you here might be able to use them and he was
just going to throw them away. Told him I'd pass his email along.
You can get in touch with him at the address in the email below.

I didn't read your web page very carefully....so I'm not sure if you
purchase computer parts. I have many motherboards, I/O cards,
video
cards, memory, etc that I am looking to get rid of.
Let me know if you are interested.

I just got my hands on my first Kaypro - a Kaypro 4. Everything seems to work,
but it never boots from the only boot floppy I have. I tried reversing the
two drives and booting from the other drive and got the same results, so I'm
convinced it's the floppy itself.
Can anyone point me to a site where I can get the software to create a new
one from my win95 machine (if possible).
I have some questions. First, I tried connecting a 360k 5.25 inch floppy from
a PC to the kaypro. At first nothing happened, then when I changed the device
select to 0, it hung the machine every time it tried to boot. Should I
interpret this to mean you can't connect PC drives to Kaypros? If you CAN,
can you connect 3.5 inch drives to it? It would be far more convenient...
Also, on www.psyber.com/~tjc/ it says there's a western digital hard disk
controller. WD-1002-05 HDO. Is it possible to connect this to a K4? If so,
how? I don't see any open connectors on the motherboard offhand.
Anyway, the guy I got my K4 from has a K2 and a K2x - the latter of which
appears to be unable to boot, although I suspect reseating the chips would
solve it, and the former of which has a soda-contaminated keyboard with
some missing keys. If anyone's interested in these machines, let me know and
I'll forward your e-mail to him.

<Actually, on the downstream side of the adapter card you are tremendously
<close to an IDE interface. As I understand it, the IDE interface is
<premised on the commands that are required by the WD1002-nnn controller.
<zI have forgotten the exact model, but it must be near to the WD1002.
Incorrect.
IDE is the buslevel equivelent of the ISA16 card WD1003WA. The register
format, addresses of the registers are identical, the interface is also the
same save for there are only three addres bits and two selects(like chip
select) where the board would take a full 10 bit address and decode it.
The 1002 HOST interface gas a different address, register command structure
though there are similarities wbeing both from WD.
To do a IDE on kaypro you would need to do the 8<->16 bit translation
and from what I have here there is not enough addresses brought out to the
host adaptor plug. That means a CPU piggyback adaptor (GIDE is one case).
SCSI would be easier as a cpu interface but the SCSI bios is a nightmare
for the 5380 type chips.
In any case adding a hard disk to kaypro requires utility software, an
interface and BIOS.
Going the turborom route and putting two to three 3.5" disks is easier.
With 3.5" drives there is auto write portect on power down so you dont need
to eject the disks and with the that would be 2.3mb of available storage
plus the 360kb drive for compatability. I have one setup in such a mannor
with an old IBM PS/2 drive inside the case (I treat it as 781k hard drive)
and two drives on the front (3.5" and 5.25" 360k). For what I use the
kaypro for that's plenty of on line storage.
To do 1.44mb would require far more effort due to data rate and the fact
that DMA is not available so it would be hardware mods for floppy controller
and also big time bios mods.
Allison
I've been talking with a guy who has a Kaypro II and a Kaypro 16. I
I already have a Kaypro II and I'm not interested enough in the 16.
Anyone out there who might like these, he used them for several
years and just wants to see them go to a good home. Hmm,
maybe I need another storage space. Let me know if you're

Taking books from the various piles on the floor and putting them
snuggly on their new shelves, I have encountered the other 50s UK
computing book:
"Automatic Digital Calculators" by
Booth and Booth, Butterworths Scientific Publications, 1956
(2nd ed, 3rd reprinting)
While it only has four plates, it is *full* of circuit diagrams,
element descriptions, and much advanced maths :) in connection with
the fundamentals of the devices.
I am accumulating material for a marathon scanning session, as I
said in the previous post on this subject. It's a stack about 2
meters high right now.
Hmmmm....

I agree with you that the 200 isn't as impressive as the 100. The flip-up display,
while possibly being a little easier to read, is just asking to be broken.
A couple of years ago, when I was covering motorsports for a local radio
station, I noticed that in the press room, amongst the guys with their fancy
color multimedia laptops, at least 2 or 3 guys would be filing their stories on
100's. Built like a tank, and you don't have to try and hunt down a special litium
battery in the middle of a race.

You can't read CD-RW's in (most) regular CD players. You'll have to keep
burning coasters until it works right.
Make sure the disc is "finalized"; that is, make sure you tell your CDR
program that you're not going to write any more tracks to the disc (some
programs also call this "closing" a disc). Normal CD players can't read a
disc until it's been finalized.
Also, You mentioned DirctCD. Most normal CD players can't read discs
written using packet-writing technology -- you need to lay out an ISO 9660
image and blast the whole thing at once (or do it on the fly, which is just
a risky way of writing everything at once).
Someone also mentioned multi-session discs -- do avoid these, as the other
poster recommended.

Of possible interest to the List, especially to our members in the
Greenwich Time Zone... I have aquired two books published in
England in the 50's... one is buried in a stack (I am building more
shelves for more books... arrgh) but is a general treatise on the
state of the art from a very technical stance. It has many great
photos.
The other book came from yesterday's TRW haul... it is
"ELECTRONIC COMPUTERS Principles and Applications" by T.E. Ivall
published by Iliffe & Sons, Second Ed of 1960. (two prev: 1956, 7)
This book covers Analogue and Digital machines and is packed with
many plates, pictures, and diagrams... it has several views of the
ACE, the TRIDENT analogue flight simulator, several Ferranti and
Creed devices, etc., etc.
I have made a picture gallery on my web site and I have now got to
scan a bunch of these things in... a project that will take only
about a long weekend to complete.... sometime in 2015 if my best
estimates are correct. ;)
But I'd like to get this stuff up, because it tends to balance the
Americo-centric focus of foundation computing.
Remember who had the first actual 'Von Neuman-ish' machine in
service.....
Also, in one of the manuals, I have a large model/feature/config
chart of all known machines from the EDSAC up to about 1966... from
all manufacturers, Germany, Japan, France, Switzerland, etc.
But its big.... oh well, soon!

Except for a significant penalty in register access time, maybe. Could
be worth it if you expected lots of context switches.
Sounds to me like the 1802. Is there any shared history between them?
Were the 1802 designers consciously influenced by the TI design, or was
it derived again from scratch?
Hmm, 1802's were used in satellites, right? Do satellite apps need lots
of context switching?

One possible problem is that I often stumble across somebody needing

them just to send mail to this list. Heck, I just got through telling
this to the guy maintaining the US EPA computer recycling web page.
He replied, agreeing to mention it. (But it looks like he has not yet
done it.) Here's the (hideous) URL:
http://epainotes1.rtpnc.epa.gov:7777/r10/owcm.nsf/d60e13abe847c4cb882564de0…
Seems like the choice is between being open to spam, being less
friendly to outsiders, or requiring constant work by a moderator.
How about making this list open to posting only from subscribers,
and having some secondary list address (ie: another list) that is
left totally open, and anything interesting gets forwarded from
that to the real list. Only one person at a time need subscribe
to the secondary list, and act as the forwarder. So Derek wouldn't
get overworked, and we could take turns on "door-duty" just by
changing who subscribes to that.
It's clunky, but it's the best idea I've had in the past sixty
seconds. :-)

Hi Everyone,
I came across a Hewlett Packard Apollo 400. Can anyone tell me anything
about this machine. I know nothing about it. I would like to know the
processor speed, approximate date of manufacture,something about the ram
amount(I do know that it has two ram boards in it).
Thanks in advance for all the help.
John Amirault
Well I'll be posting things as I get throught them since I have a move
in the next 6mos to a year ahead and there's way too much here. I'll
only post what I think the readers of this list would be interested in,
at as low a price as I can go.
I have an IBM PS/2 model 50Z (286) with factory tape drive (unknown
format) that is fit into the B: drive bay, and a 360k external floppy
drive unit (IBM). No keyboard or monitor. I believe it has a 30 or 40mb
hard drive and 1 or 2mb ram. I gave over $35 for this machine without
the external floppy, basically on a whim for future use. I haven't had
a use for it yet due to no time. I'd like to see this unit get used
where it will be appreciated. You can even bump it up to a 386 with one
of those 286 to 386 upgrades like a "Snap-In" made by Intel or others.
The tapedrive slot looks like a QIC-80 size but taller. Like I say this
is unknown but should be common enough.
Shipping weight from 40144 would be roughly 32 -34 lbs. I need to see
$25 for the unit and external floppy drive, plus the USPS shipping. If
you are near the central US, shipping shouldn't be too bad. It all works
great but the only thing on the hard disk (IIRC) is DOS so you'll have
to visit IBM's FTP for the tape and floppy drive drivers, no big task
though for most of us. All the hard ware is IBM so it should be an easy
thing to locate.
Email me driect at RHBLAKE(a)BIGFOOT.COM if you might seriously be
interested.
I love the add-on from Doug - priceless <grin>!!!
Also, for when you absolutely must get an antique HP part that isn't
available, and you've reached the end of your rope and are now willing to
pay severe cash for it....
There's crisis, mbg, and norco. They all still sell stuff for HP1000, 2100,
21mx, A series, etc.... and more. Be warned, the prices assume you are
buying for a business use system - they give new meaning to the term stiff
pricing. But - in a pinch...

Oh - I didn't know anyone here collected Prime computers.
My company used to specialize in Pick and Pick-like operating systems (such
as prime information and the honeywell dps6 version of Ultimate OS).
If anyone is looking for Pr1me gear, I know where most of it in the St.
Louis area is... probably know a few customers who still have their DPS6's
in storage too. Just let me know...
Matter of fact, I know where a completely working Prime 2550 with 1/2 tape
drive bay is. They said anyone could have it, just cart it away. It's in
pristine shape, along with all load tapes, docs, etc.

Hi Jay,
I wanted to reply to you.
I have a system that you might be interested in.
It's a 2100S Microprogrammable System Computer
It is a rack mount box about a foot high and 2.5 feet deep.
I also have a similarly sized expansion box for it.
These were pulled from a large bank of racked surplus
equipment. It was all wired and presumably working when
it was decommissioned. Although I've never applied power
to it. In fact I also have some kind of an HP monitor that was
attached.
Both units are populated with cards (including HPIB interface
cards and the cables to interconnect the two boxes).
Someone once pointed me to a photograph of this system
on the web, but I don't recall off-hand were it is. It has
little square luminated push-button switched on the front of
the primary box. The expansion box has a plain front panel.
If this is the kind of item you're looking for we might be
able to trade. I don't think I'd want to sell it outright. I didn't see
where you were from. This unit is REAL heavy. Each of the two enclosures
probably weigh about 80lbs so would probably be
expensive to ship.
I'm located in New Hampshire (zip 03103).
I collect homebuilt kits and single board computers and
related materials including documentation from approximately
1965-1985.
Kind of things I'm looking for:
Altair :: Imsai :: AIM-65 :: An original ELF :: Ohio Scientific equip.
Ithaca :: maybe a PDP-8? :: definately a SCELBI H8

Golly! I recently passed up a $10 dual 150-meg unit at the local junk
store. If I'd thought someone had that many cartridges in one place, I'd
have bought the thing just to pass along to someone like you.

I recently found a Xebec hard drive/box/powersupply arrangement in a thrift
store. Since I was after the box and supply, the fact that the controller
was integrated into the drive hardware, which made it almost completely
inscrutable, was not a problem. If someone wants these remnants, they're up
for grabs for the shipping cost . . .
I also have a Tandy portable computer, which I was given, which might be of
some interest to someone. Since I don't know a thing about it and don't
want to learn, this is also available for the cost of shipping. It's quite
small, but not exactly "pocket size" though I guess it's closer to that than
to a desktop of the time. I was given a wall-wart and a cable along with
it, and it has an integrated printer, I believe.

Subject: Some finds and a few questions
I finally had a chance to get out and hit a few thrifts again. I was
chained in a studio working on an anime, but I'm free again.
Anyway, I found a Xebec Sider harddrive. Was this for the Apple //?
Something was loose inside so I checked and found a small
rectangle filled with some ceramic like stuff and a wire sticking out
of each end inside of the PSU. Can't seem to see anywhere in the
power supply where this thing may have come from but also can't
see how it could have gotten inside if it didn't belong. Not even sure
what it is. Any ideas anyone? Also would like any info on the
drive type, size interface, etc. It is a model 9710H. Looks like I
can pull the drive from the case and hook up a different PSU.
On another note, anyone tell me anything about a handheld unit, I
think it was an LK-3000 or some such, I'll have to go back and
check. The guy wants $50 for it and also has a Tandy Pocket
Computer for $40 I'm thinking of picking up.
Other things I grabbed:
Odyssey2 in box
Coleco Adam in box (damn big box for a home console system)
Atari 1040STf (may sell/trade this as I have one and an STfm too)
Couple of Apple 5.25" drives
Misc software and books
For those of you who were interested in the Mattel Aquarius Data
Recorders, after two months of no replies to my query on where to
drop off the money and pick up the recorders, I have finally given up
on them. They said they accepted my offer but then they just fell
silent. Guess they found someone else with a better offer.

Today I run into a Monroe CAA-10 electromechanical calculator,
totally accidentally and unplanned. I am not in electromechanical
devices, but it looked nice, so I bought it for approx. US$60.
Question: Is this in any way rare or significant, or is it something
where everybody has already 10 pieces of ?
Does anyone know the manufacturing period ? There is no date on the machine,
but the style impresses me as definitely 50-ish.

If any of you have Kennedy tape drives this
might interest you.
I was at the local Junk store this morning and found
a box full of the rubber o-rings that are used on
the Tape reel retaining latch (both reels).
I bought a couple and compared them to my
originals and they appear to be exactly the same.
They are in good condition, still flexible and supple.
No dryness or cracking.
If anyone wants me to pick up any let me know.
They're 50 cents apiece plus shipping, which shouldn't
be much.
There were quite a few so I don't think that supply is a
problem.
Let me know soon.

I'm going to try to keep this on-topic (or at least close)... My parents
had a '60's Victor, which cost big $$$, but was no longer used, so they
kept it in the attic. Occasionally, they'd bring it down and let us kids
play on it, but I was the only one who had any interest in it whatsoever.

When I was 11 or 12, I broke the Victor in a non-violent way, but had no
clue how until a few years later...
See, this Victor had the ability to divide, and at the time I broke it, I
had no idea that dividing by zero was a bad idea.....
Damn, the racket that thing made (and still makes today if you plug it in)
as it tries to keep dividing by zero whenever power is applied.
Can't do it on computers now, either. (Thank goodness for error trapping...

Kodachrome is more tolerant than many films, but in general you'd need

The Daily Laugh spam originated from the domain virgin.net, which is
hosted by cableol.net, a UK-based ISP.
I have sent a formal request to cableol.net to curb their customer.
Based on the very tough stance against spam that most UK ISPs seem to
take, I don't think we'll be hearing anything more from virgin.net.

That's the most obvious difference, and the only one you'd need to consider
for a static subject with a camera on a tripod, at "normal" shutter speeds.
As Tony pointed out, a moving subject will be subject to greater blurring
at slow shutter speeds. For a hand-held camera, there will also be some
evidence of blurring due to the unsteadiness of the operator; for a normal
35mm SLR in competent hands you'll typically start to see this at speeds
below 1/125s. As Tony(?) also mentioned, at *really* small apertures (f/22
or smaller) the definition falls off, even though the depth of field
increases.
There is another difference, of particular importance to colour film, due
to what's know as "reciprocity failure". At very short and very long
exposures, the "double the aperture, double the speed" rule breaks down,
and you find that you need longer exposures than you might expect (because
of the particulate nature of the film emulsion, and the activation energy
of the silver halides and dye sensitisers in it). For B/W film, that just
means it seems slower outside the normal shutter speed range. Astronomers
are well aware of this, for exposures of a minute or so, speed can easily
drop by a factor of 2.
Worse still, colour film is actually made up of three or more layers
(typically 6 layers, plus a dye layer), and they aren't all the same.
Although they're balanced for "normal" eposures, reciprocity failure
begins to show itself at different times for the different layers. The
effect is that colour balance can be wildly different at very short or very
long exposure times.

Also, ordinary B/W film is "panchromatic" -- sensitive to most of the
visible colour range (and also to UV, which is why most professionals tend
to put a UV or "skylight" filter on every lens as a matter of course).
Paper and process film is usually "orthochromatic" -- insensitive to reds
-- or "blue-sensitive", which is why darkroom safelights are usually
yellow.
By "indoor light" I assume you mean tungsten lighting? Yes, it's redder,
but you need a *blue* filter to compensate, if you're using "daylight" film
(which is what most ordinary colour film is). These filters usually have a
filter-factor of about 2 to 4, ie they cut the effective speed of the film
by between 2 times and 4 times.

Well, i figured it was about time I took my terminal out of the closet and
tried to get it to work again. Well, the good news is it still appears
to be working.
This beast is a Control Data Corporation Plato terminal. As far as I know,
its the original model of plato terminal. Touch screen, vector graphics,
square monitor area... big base unit a tad bigger than my IBM pentium
computer, with a video display unit that sits on top and merges with
teh base unit. Keyboard is about as non-standard as i've ever seen.
There are side panels on both sides of the base unit, which contain all
the circuit cards for the smart terminal. It looks like this was made
around 1975 since the proms are dated then, and some other board had a chip
dated 1974... 8080a cpu.. I have the optional modem card, not that i can
use it (1200 rcv, 150 xmt ;) ;)
This baby can support all sorts of baud rates, most of which are useless ;)
Lets see, if i recieve at 1260 baud, i can transmit at one of these rates:
1260, 630, 157.5, 126, 78.2 baud.
If I recieve at 1200 baud (yes! a useful rate) I can transmit at 1200, 600,
150, 120, 75 baud.
I only have 4K ram, does anyone have a spare 4k ram board for this ;) ;)
I can see why I havent been using this, it looks like I need to wire up
a rs-232 adapter box. Pin 3 is recieve, pin 14 is transmit, pin 7 is ground.
Am I correct in assuming that i just need to move 14 to 2, or am i getting
2 and 3 swapped around? I woudl want to connectthis termianl to a cp/m
computer as its console, and not to a modem.
Ok, time for the impossible question: Does anyone have a manual for this?
I had some leftover old 1000 speed film in teh old automatic-everything
el-cheapo 35mm camera, so i turned onteh flash and snapped a few photos,
so with any luck i'll have some poor images of this beast by tomorrow.
Hmm, if no manual is available, maybe an old termcap entry might make
this terminal useful again....
How many thousands of dollars is this beast worth? i may go broke buying
cloth covers for this stuff ;)

I think Tony and Jim have said most of what I would say, but:
Use the longest focal length you can while still getting the required
magnification and fitting within the room. A macro lens is very useful
here, or, failing that, extension tubes (but if you don't have
through-the-lens metering, remember to correct the f-number for the
increased distance between lens and film).
The slower 35mm films are pretty good with a decent lens, but if you can
get the required magnification with the polaroid, it may be worth
considering since it is likely to be a less grainy process, and a larger
film area (i.e. lower resolution per inch <= same resolution across whole
picture)
I have little experience with lighting computer stuff, but I imagine (say)
a board full of chips might require several light sources to avoid the
chips casting strange shadows.

Something this useful just has to be illegal. or fattening.
ob classiccmp:
does anyone know of a (cheap) source for bernoulli cartridges? I have
snarfed a 90 transportable from work that was being tossed, and I like it.
The zips and sparq's, jaz's, etc, they all seem, well, flimsy. This guy's
a tank.
Also, does anyone need any 20Mb bernoulli cartridges? I have a bunch.
