Is a PS/1 machine considered to be in 'family one'? My school had a PS/1
486-25 (processor speed, not model#) Consultatnt (I think), that when the
HD died, it booted to IBM BASIC. It was also able to access the drives,
but was in ROM BASIC.

In any case, he doesn't win every auction he bids on (though, from what

I came across an ebay page that suggested a good way to find your true
maximum: First pick what you think your max bid is, say $50. Now, close
your eyes and imagine that the auction is over and someone got it for $51.
How does that make you feel? If you're upset, set your maximum to say, $55
and try again. If the thought that someone would get it for $56 still gets
you upset, do it again. If you get to $110, and the thought of someone

Very true. Assume your max for item X is $100. Opening bid is $1. You
bid $100 on the first day, and the high bid is $1. Day 2, another bidder
comes along and bids $20. You still have the high bid for $21. The other
bidder sees that and tries again, this time putting in $40. Your bid is
now $41.
If, however, you wait 'til the last minute, the other bidder will bid $20
and that's it. You can come along at the last minute and snipe him for
$21, saving you $20.
Keep in mind, too, that not all categories get the inflated prices that the
older computers get. I've got a box full of Donald Duck stuff (Rachel's
birthday is 11/9) that I got at prices ranging from decent to outright
theft.

The answer to sniping is to keep bidding open until no bids have been
received for x minutes. That's the way some of the reputable collectible
auction houses do it.

Yep. Dead right. 12-15v dc to feed a dc-dc xvtr that produces 9v to run

Exactly as you recalled. I have the PDF files with data for the lot.
Amongst other things, there is a page with a "Typical Application" which is
a cct diagram of a what amounts to an AUI-Thin cable transceiver. Complete
with pinouts of a typical pulse xfmr. Exactly what I needed.
So I'm gonna build me a couple or three from bits of network cards. Should
be able to do it on
a piece of veroboard in about an hour or so. Cabling can be avoided by
connecting the pins of
a male 15pin d directly to the veroboard, then the whole thing can plug in
to the ethernet AUI port on
the back of the VAX.
This has basically solved my problem, as I have several elcheapo ethernet
cards laying about
that can supply all the parts except the 15 pin male d.
Thanks for your help.

That's OK, it took me two years to run the two serial lines from my room to
the garage, and four more to do the coax. Now I have to run Cat5 as

I don't have it anymore, it had a lot to do with sampling and compression,

Well, as someone who learned 10-key touch before I learned to type, the
idea of a comma on the keypad does not seem so obvious. More important was
the plus, minus, and period keys, for true data entry.

Briefly, here could be a solution to us inadvertently posting what should
be private replies to our whole list:
Can listproc on the U. of Wash. server be set so that the "Reply to:" field
defaults to original poster and not to ClassicCmp?
For example, Majordomo software running on a server handling a different
list I am a member of is set this way. Therefore a reply will go to the
previous sender in a msg thread. If the message is to go to the whole list
then we simply type the "r-390(a)qth.net" address into either the "To:" or
"CC:" field. Works very well it seems. FYI: 'R-390' is the military
nomenclature of a high performance military surplus shortwave receiver that
is truly a "classic" as far as its owners are concerned. I would even wager
that Wm. Donzelli may have one too.
As the reasoning that the message should always go to the list, we should
just remember to specify the ClassicCmp addr. in the "To:" or "CC:" field.
If we do not see a msg we intended for the list come up in our own email
Inbox later then we know that we accidentally forgot and then have the
option of reconsidering sending it to the whole list. This will help keep
personal stuff such as discussing a deal to buy/sell something from the
rest of the world --or those flames that get thrown around which nobody
here appreciates.
I'm still waiting for M$ s/w that works well.
Whatever happened to Bill Whitson anyway?

I know the problem all to well. They just have no sense of humor on such
things. I moved all of my equipment to mobile homes I use for office and
storage. 4 now soon to be 7 all sandwiched together. Now I get complaints
that I am never down at the house, but when I bring things down there to
work on they are in the way. Now that the kids are off to college I plan to
take over one of the bedrooms and put a system in there. I even have a 4
inch conduit running the 350 feet from the office to the house. It is
buried in the same trench as the power, phone, water, and sewer feed to the
office. It has been there for 4 years and I still have not run the coax

The first paragraph sounds familiar. Liz complained about the black cable
snaking along the landing -- even though she finally got email and remote

TBOTA:
Does anybody remember a 'INTEL' video game ? I have
aquired today a unit named 'INTEL UNIVERSAL TELE PLAY'.
Acording to the chip dates the base unit (there is
only the video logic and the connectors inside) must
be manufactured around 1976. The two modules (here is
the processor) I got, SUPERSTAR (a collection of Pong
alikes) and TANK are from 1977 and 1978.
The unit is very nicely, a plastic case with metall
plates, 4 switches (on/of and 3 game dependant), a
Start (Reset) Button and even a numeric keypad to
select games.
Funny numbering on the keypad:
159
260
37*
48=
maybe taken from an old calculator.
The base unit has a German/English mixture of
labels, while the modules (cassetes) are only
in english.

No, I have no C4P, but I still would like to get this board.
Maybe I can dig up other parts over the next years. Wasn't
the C4P Board already a complete computer ? At least thats
what I remember. So adding a Terminal and a PSU might be a
first step to check condition.

including the two i own. i guess it could still be useful with a floppy
because you could always run those programs on cartridges.
i have no idea why the ps/1 was announced after the ps2. perhaps was just an
afterthought. i've had people actually think that the ps/1 was "better" than
the ps/2 just because it was first.

this way, but I'm just not in the UK ...and thats what the
thing was about - I already had some talks to Wirtschaften
(some Pubs) over here about this, and a meeting somewhere in
spring might be reasonable. But it would be a Bavarian (German)
mini VCF, and beside the travel distance for our UK list fellows,
the Meeting language will be German, at least for most people,
since the goal will still be to attract more visitors. Of course
everybody is free to use what ever language is possible to talk,
but if there is a programm of speaches to be made there will be
problems. On the other side, we might attract new followers for
the list.
So, when only looking at the list I belive a UK (informal)
meeting might have more members visiting than one in Bavaria.
But feel free to prove me wrong. If there is a response,
I will voluntere to organize it.

Thats the simple way of avoiding any possibility, as far away
it might be. An empolyee like you described could even in
Germany, where we have very strict laws agains random kickin
of employees, be fired winthin some days. AND will be responsible
for any possible financial loss - Thats a bit like your cracy
pruduct cases. So taking of parts is ok at most companies (with
permission) but using them for profit (no, a single sale at a
flea market is also not considered profit) could harm you more
than being charged with murder.

Of courese - extending the usage of any thing is the best
environmental protection strategy (maybe without suizide),
especialy with wares that used a lot of energy and other
recources to produce - often a lot more in construction then
at any time later - like cars or computers :)

Yes, and only in the US. Ok, our European product laws
are maybe sometimes a bit week, but the combination of
better rights for the customer and a very junky law system
isn't helpful either.
And worse, if we would bothe get hurt (in the US) I have
to be lucky to get 1/20th of your payment ... American

Almost same for Germany, although the point of changing
ownership is depending on the contract. In most cases
the ownership changes when the item ist dumped, althrough
no court will rule agains a dumping person when the item
is taken back. The same is true for any public trashcan/
dustbin. As soon as it is droped it belongs to the owner
of the dustbin.

Anywhere from $5 to $200, depending on options, condition, venue... I got
a 32K model in nice shape at a flea market for $14 (Thanks Rax!), and have
paid over $100 for a mint condition one, with RJ-11 cable, acoustic cups,
tape player, 32K, hard shell case, floppy, manuals, slip case, etc.
If you just want one to use, you should be able to get one pretty quick for
$50 or so. If you're willing to wait, you may find one at a thrift shop or
flea market for much less.
Keep in mind, also, that other versions are available: The Nec PC-8201,
PC-8201a, PC-8300, Olivetti M-10, Kyocera KC-85, TRS-80 Model 102 and Model
200 all are either very similar or identical. Note that the NEC PC-8401A,
Olivetti M-15, and Radio Shack Model 600 are *not* related, other than in
similar names.
Also, I would be more than happy to trade a true m100 for pretty much any
of the others (except maybe the PC-8201a) along with some cash if they
didn't suit your needs (not enough memory, no modem, etc.)

If I may butt in... Perhaps there is a way you can do this. First, pick a
location that you think will be convenient for everyone, perhaps near the
chunnel(?) or near an airport. Then, find a pub, restaurant, whatever with
a decent sized meeting room and convince them to let you hold it there for
free. (Often, they'll do this because they figure attendees will buy lots
of beer/food/whatever.)
Next, pick a date. Get together with your core 5 and find a mutually
agreeable date. Plan for 1 day the first time. Let people know about it,
arrange for some computers to be on display, maybe a speaker or two, dig up
some vendors, and go for it.
Costs should be minimal -- printing some flyers, maybe. Income will be
minimal too (perhaps charge vendors a small fee) but can be used as seed
money for the following year.
At the very least, you'll have 5 people getting together for a day of
BS'ing about old computers. At best, you'll have a decent first shot at
it, with the momentum to really do a bang-up job of it the following year.
I think starting out with higher goals worked here because of the high
concentration of techies in the Silicon Valley. Over there, I think a more
modest start makes more sense.

I just had to stick in my 2.1 cents worth (inflation, you know...) on this
issue. I will *never again* use 10base2 for plant wiring for the simple
reason that 10base2 (and 10base5) provide a ready path for "ground loops"
between all the equipment sharing the cable. It's true that the "grounds"
are "supposed" to be isolated (to the tune of several Kvolts) from the
computer connection, but, believe me: "sh*t happens." And the results
can be dangerous.
10baseT is designed to be isolated at every connection point in the "star"
configuration (high-isolation transformer coupling,) so there is a much less
likely path for the "big ugly voltage" from one piece of defective equipment
that just happens to be shorted to the Ethernet 10base2 cable. You don't
get killed when you reach behind your computer and grab the Ethernet cable
and suddenly find it has 480vac on it due to some stupid short in a control
cabinet. If the 10baseT cable is shorted, the hub has a high potential, but
it never makes it out to any of the other cables plugged into the hub.
Both of these scenarios assume correctly isolated cable-to-interface
connections. It's just there is nothing isolating the bad stuff from
you when you touch the cable shield. The necessary hub on 10baseT
keeps the bad stuff from getting past the first short - assuming you
*do* use a hub...
And making 10baseT connections (with the proper 50US$ tool) is MUCH
FASTER than making coax connections, if speed is important.
Of course, the better (best?) approach is 10baseF, but it isn't readily
available for us with home installations (at least not at the price *I*
want to pay.)

Actually the addres bus can be smaller than register size. For example
we could build an 80 bit machine with 60bit address busses. The 60 bits
is more than enough to address most likely memory needs for a long while
yet if you need to do address math or other math 80bit long registers may
make it much easier. The datapath bus can be any size as well but larger
is generally better.
The assumption of symetry is likely the most false.

Oh, RJ45's are no problem provided you have a decent tool. I use crimp on

<GRIN> Actually, this thought also crossed my mind whilst gazing at just
such a card.
I'm going to try that. I have an NE2000 clone card I'm going to try and
convert to a txcvr.
I think it needs +-12v and +- 5v, but that's not a big problem. (Diskless

Not even gonna try. A direct patch into the txcvr from the AUI port with a

Hmm. "Square" isn't the best way of putting it. In English we generally
call that an "exponential" or "power" function: for an address bus of n
bits the size of the memory is 2^^n words (pronounced "two to the power of
n"). That's what I was getting at in my post.
I agree totally that data paths should be as wide as possible. It wasn't
just vaxen (Good post, Allison. A lot of very good points that I hadn't
thought of) and mainframes that did that - the PERQ was a 16 or 20 bit
machine but the memory data path was 64 bits wide (Help! Tony, you know
more about this!) and fetched 4 words at a time for the processor to chew
on, then 4 words for the video, 4 words for the I/O etc. Huge increase in
speed.
Address bus should be as wide as you think you might need plus a bit more.
As Allison said (again! Why oh why did I delete her post?) you want your
processor to be able to think about huge memories even if you can't build
them and have to swap to disk.

I belive your idea could still be done on a second server.
For your proposed testrun, a real check about the members
of ClassicCmp to allow access for the sidebar list is not
needed. The listserver will only be made public thru this
list, so any subscription from outside is kind of uncommon.
And even if there are some few, they shouldn't change the
result in a real way. If the idea is right, an add on for
the 'real' server might be made. Or we keep the second and
just exchange the member list every other week to check the
data base and we get another foot to stay on.
Merging both lists into one folder should be no problem for
any mail client out there (also splitting it up again into
several theme folders).

I might be proved wrong, but I belive this chip had
a vital role to turn down the wall. In 1985 the Eastern
German government decided that they had to pull up with
a 1 Meg chip to show that their system is able to do
all the same fine things than the west, all of us might
temember that the 1 Meg thing was kind of journalists
pussy when talking about the future back then. They
already cloned the 80286.
For the next years they poured all resources within
electronic and process development into this project.
It was almost like the idea of building a a PDP-8
>from scratch that has been around :) Of course, they
already had a technology to produce 64k and prototype
256k, but without any help from outside it's kind of
uncomfortable.
Short before the wall came down, they finished, but
at what cost: the whole development was sucked up
into this single project - anything els was almost
like stopped even production of actual components
suffered.
So this project added a lot to the economoc problems
witch eventualy lead to the end of their system
You know - people without video games and home
computers tend to think about dangerous things (<g>).
I'm not telling that this development has been
the mayor reason, but it added stress to an already
stressed system.

Nice talk, but just think how hard it seams to be just to
change the Subject line at the right moment AND to get all
participants into changing it - not to mention the time delay.
This is just an international thing - when I get up and have
a first look at it Allison is still sleeping, Uncle Roger
(or the other US West Coast guys) are just about to find their
sleeping position, while Olminkhof is right about to leave
the office - I've seen these things from other lists and
news groups. It is just impossible. It is even impossible
to live such a policy within a worldwide collaboration tool
for a project. Even when corporate and special rules try
to enforce it.
And Moderation is just the dead of any list (maybe beside
a anouncement list for 0190 (1-900) services, where they
don't need any spontanous answer.

Thank you. I hope I'm not hurting your eyes to hard. Fact is that

Ok, I've gotten most of my stash transcribed into text documents on the
site. The exception is the bus section, which contains a list of those
pinouts that I have but am still working on.
Anyway, what this really is is a request to people to dig through their
piles of old docs and add some pinouts that aren't there yet. Tony Duell
has offered to do PERQ machines, and anyone is welcome to contribute
anything that's not there already. I put a file in the "pinouts" directory
named "contributors.txt" which contains specific info about who is working
on what.

Well, not if you're accustomed to TS-EDIT on the Tandy Color Computers! vi
is a superset (I believe -- been a long time since I used TS-EDIT) but the
CoCo clone is a fairly complete implementation of it.
One thing about vi / TS-EDIT: 'tis a pain in the rear to use, until you get
accustomed to the commands. If you do become highly accustomed to editor,
you can go *very fast* with it.
Boy, I miss those good old days... ;-)

This is a question that has been dealt with very thoroughly in the
past.
Sydex (http://www.sydex.com/) has some very excellent software
available for dealing with "foreign" floppy formats, and can deal
with many (but not all) 8" floppy formats. Instead of going into
great detail on how to use these tools, I will instead just refer
you to the CP/M FAQ at
http://www.cis.ohio-state.edu/hypertext/faq/usenet/CPM-faq/faq.html
specifically, Q14: "Can I read my 8" disks with my PC?"
I hope nobody takes this reply as a brush-off as a result of
a good fraction of my business coming from reading old media,
including (but by no means limited to) 8" floppy disks. Even though
references to non-mailing-list resources seem to very sparse
on the CLASSICCMP mailing list, I just want folks to know that
there *are* very useful FAQ's out there that deal with the issue
thoroughly already.

Thanks Tim.
Speaking of road trips:
Next month I going to take my two weeks vacation to retrieve our
belongings from storage in Manassas Virginia, where we left them
11 years ago. I'm excited to be finally getting my two analog
computers out here to California. Anyway, we will be driving
back to California from Nov 14-22. I'm hoping to stop at a few
places on the way back, looking for (real old) computer stuff.
We already plan to stop in Pennslyvania,Ohio - Lima and Aurora,
Michigan - Benton Harbor and Ann Arbor,Chicago,St. Louis,and
New Mexico - Albuquerque.
If anyone knows of good places to look, and want to share the
secret, let me know.
What kind of places? Places that dark and dirty. Places with
junk arranged in piles. Places with vacuum tube equipment.
(I would love to find an example of a vacuum tube analog computer)
Places you won't want your kids to play in.
On another note: Does anyone in Florida have more information
about the plans to tear down the original control room at
the Kennedy Space Center? (It was on the news)

There IS a huge distinction, there is no such thing as a "fair price."
Its a myth, it don't exist, deal with it. If this "schlub" as you so
affectionately refer to them knew about your thrift store (and I can
guarantee you he will) then you won't find Atari's in thrift stores and
you won't find them at swap meets and the _only_ way to get one will
be to pay more than what some other "schlub" is willing to pay. And if
the price is too rich for you then you won't own one. What's a "fair"
price for a Picasso? a Rembrandt? That is exactly what a market IS
and it is actually _incredibly_ fair. Without external intervention it
will settle on a price that people are willing to pay. To use the 1200XL
example.. Word will get around that a 1200XL goes for 600 on Ebay, so
enterprising folks who have been in thrift stores will start scrounging
around for them, and then they will all put them up on eBay and the
large number of them will cause the price to come down, probably way
down but it may not get down to a level you are comfortable paying.
For heaven's sake, you think there is a "fair" price for a house in
Silicon Valley? Of course not, the MARKET supports a median house price
that is well above what any ordinary mortal could pay for, but only
because there are enough people willing to pay that price. When people
said, "This is f__ ridicululous!" in 1991 guess what, houses stayed
on the market until the price came down. When I bought my house I
offered nearly 100K UNDER the asking price, got the house and it STILL
lost 15K in value over the next couple of years! Now its going back up,
great, but that will change when the guys from eBay who got rich on
the IPO have all bought there houses.
Economics, not just an idea it's a discipline that actually predicts
these things pretty accurately...

Just a note to people: when you e-mail someone directly; don't use an
email-address that has something like "your name
<yournameDIE.YOU(a)SPAMMERmydomain.com>" in it. Using Microsoft Outlook
(which I do), it just shows <your name> with the SMTP portion hidden. After
the mail bounces, I'm less inclined to type the whole message again and edit
your user name. So that reply to you offering to sell you the complete
Altair for $50.... well, you didn't get it.
I mean, it's a direct e-mail, not the mailing list. If you think I am going
to spam you... come on.
Ok, now that, I've jumped all over Arfon, I have to say it's nothing
personal and I apologize in advance. it's just not the first time that it's
happened. it's just that I don't even see anything until the mail bounces.

Look, I don't know if this was supposed to be a private mail, or not, but
WHATEVER it is, it's DEFINATELY OFF-TOPIC! I really think I'd have to side
with Sam on this one.

virtually everyone on the list and have created yet another flame war
which has no end in sight. Please be advised to re-read the Classiccmp

Well this list used to be good, now it has degenerated into 80%+ noise.
I joined the list some time ago because it was a means to get information
about some of the old computers I have collected, hardware and software

What does a 64 bit Z80 have to do with old computers
What does gripes about EBay have to do about old computers
What does a modern college education have to do with old computers
I have been watching closely what has been comming though and I have found
that by just looking at the heading I trash 95% of all messages, spot

Go back and re-read what this list was supposed to be about.
99% of useful information I now get is off other peoples web sites.

< already in use in main frames - only called data path),
< even a 128 Bit address bus is just nonsense.
There is some truth to this. DEC went to 64bits as they knew 32bits
were not enough for some applications. They were also trying to design
for the next 20years to repeat the life of the VAX (32bits).
Now, having a large address space isn't completely about filling it.
It's about having addressing modes and arithmetic adaquate to deal with
large data objects. In the 32bit model 4gb is the limit without
thrashing. Those limits was exceeded by disk farms with tens of
Gigabytes of databases and solving large mathmatical models. The
current example would be doing windows graphics programming
(1280x1024x16m) using only 16bit pointers, you do a lot of thrashing
to get the the next 64k chunk and there will be a lot of them! That
was the problem that spawned the VAX!
Brief history lesson: The PDP11 was reachhing the point where a fully
filled machine (4mb of ram) could not process in one lump the large
problems like weather models or MRI data. It was NOT a speed issue it
was 16 bits made for too small a data pointer. Also doing 32/64bit math
required more steps (or FP hardware) as the registers were all 16bit.
So to add two 24bit numbers on a PDP-11 required multiple steps and that
was a speed impact. Going to 32bit registers made that a single
instruction and paid back as speed without processors running at faster
clocks.
If it were speed the 11/74 would have been an ongoing event rather than
the 4-6 than did get made. The birth of the VAX (and DGs Eclipse) grew
>from this need.
So computer designers bumped the size of things to assure they could
comfortably address the likely largest object they can resasonably expect
to see for some time to come. Not so they could have 2^64bytes of ram
but because they already have 2^40bytes of disk farm!
All this was no surprize to computer designers. They foresaw it in
the 60s knowing that larger memories and disks were needed to solve the
problems that were growing.
The datapath issue is strictly about speed as the VAX could have an
8bit data bus (in a trade for speed) like the 68008. While it has a
big effect on speed it has no interaction with addressability. It's
addressing the system problem of multiple devices competing for the
common resource (MEMORY). By making the datapath wide you can grab
several bytes at the same time and while the cpu is dealing with
that the ram is available to run a IO cycle to a disk system or
other IO. How big wide enough is, that is determined by how much
silicon you have.

I disagree. In between Q14 and Q16 of the CP/M FAQ, and the reference
to Sydex's tools, everything you need to know to make images from physical
floppies and physical floppies from images on a PC-clone is in the FAQ.
Q16 will even tell you how to use a 5.25" or 3.5" floppy on your
Model II.

But it *is* a FAQ in many other forums, and has been repeatedly discussed

I'm not objecting to the thread; I'm simply pointing the group towards
an already extremely comprehensive source of information, because
this is a better practice than repeating stuff that most folks here
have already seen many times before.

Basicly I think its about integrations and transistor
equivalents, but this is just linear to the size of memorys.
In fact, to come back to the original question, Arfon
just took doubling of address space and doubbling of
data bus width for the same thing, but in fact they
are two different functions - widening data bus is
linear, while widening address bus is to the square
(sorry, my mathematical english just stops here).
This means doubble the data bus just doubbles the
date transfer rate (the only thing the data bus is
needed for) or w'=w+w. But doubbling the address bus
is putting the address range (and thats what the
address bus is for) to the square or r'=r*r.
So, while a 256 or 512 bit data bus is usefull (and
already in use in main frames - only called data path),
even a 128 Bit address bus is just nonsense.

Coming from someone with a 24-line signature, ragging other people about
appropriate mailing list behavior strikes me as just a bit hypocritical.
Every time 1 or 2 people make noise about "noise" on the list, Sam jumps on
his "This list needs a moderator and I'm the man for the job" soapbox and
everybody grumbles about leaving until he settles down; I don't really see
the point. Judging by the relatively small number of complaints, I'd have
to guess that most of the users (myself included) don't have a problem with
the way the list is operating. I typically read the mail from this list in
batches, as I have time; I use Forte Agent, and have a rule set up to sort
messages from "classiccmp(a)u.washington.edu" into a seperate folder, just
like I do the other mailing lists I'm on. That way, I don't have to wade
through list messages to find my personal e-mail. I guess I'm with Max - if
you want an encyclopedia, get one. I prefer to deal with my on-line friends
and neighbors as whole people, not chopped up according to arbitrary
criteria and stuffed into neat little pigeonholes just to keep a few
anal-retentive people happy...

Why not just take an Alpha if you want Alpha features ?
And now tell me where you need 128 Bit address ? Just in
case, even to fill a 64 Bit memory you need 4 GIG of
mem thats just 4 grand ... and 128 Bit memory used ...

Lets just assume you need only 4 cycles on your
micro-controller to do the equivalent of an Z80
cycle (after all they are software controlled).
this means a 400 MHz micro controller equals
a 100 MHz Z80 with an sustaind rate of around
25 MIPS - thats just double to tripple the rate
of an Z180 - not a big deal - and anything faster
would require Memory with less than 10 nS access
access time - and if you remember SDRAM design,
there are some quirks to resolve - your simple
Bus concept is dead.
And speaking of timing - at 1GHz, a signal
traveles less than 30 cm (or less than one
foot if you like the ancient way). If you take
just 500 MHz and lets say 1.4 ns of switching
time, wireing at hobist level is impossible.
just forget it - these speeds are only possible
inside of chips - gee even chip designers have
problem with the path inside the chip, and you
want rant about using special socets ?
> I can parallel them to make them read-in and intrepret Z-80 code.
Paralell them - interleaved (pipelined) or even
out of order execution ? Have you ever been involved ?
O3 is the crudest thig one could imagine - you need
5 to 15 times the logic of the active components (ALU
etc.) just to coordinate the concurent components.

What about taking an extreme simple CPU and try to think
again on a simplified base - I would suggest the 1802 -
one of the simpelest designs - less than 300 gate function
as I remember. No complex math just addition no fancy
OPs just minimal needs. And now try to think about
O3 and parallel concepts at this simple base.

See above.

A one cycle ALU is still faster - and when using 64 or
128 bit math you need more ROM than available on earth.

IBM 21xx series were PS/1 and current aptiva models. the earliest 21xx series
i know about is the 2121 386sx types that had the power supply in the monitor.
2121 models do have a similar form factor though. i'll check at work and post

Has anyone ever seen (or heard of) an IBM PCjr with no internal disk
drive, but instead a face plate covering the slot where the drive would
go? I saw such a thing today and was curious if there were ever any
PCjr's released without internal disk drives. Obviously this one was.
The inside is rather bare as well. There is not the usual cards inside.
I also saw what looked to be a very small IBM computer. It had all the
connectors on the back, for video, keyboard, printer. It also had two
3.5" bays side by side in the front. The front cover was missing so I
couldn't get any model number off it (not even on the label on the
bottom). The only thing I saw on the label was "Type 2100". I'm thinking
it might be a PS/1 or something. It was really small, measuring about 12"
wide by 3" high by 12" deep.

I once bid on an item and saw the "auction has closed" screen. Then, ebay
decided that because a problem came up shortly after the auction closed,
they would reset all the auctions (even the ones not affected) to close one
day later. Imagine my surprise when I checked MyEbay and saw the auction

Hi Group:
I have an old 11/23 with an H7861 power supply. It's a Q bus box. The
cabinet kit is missing. There is a ten wire ribbon cable from the power
supply. I am looking for the pinout of this ribbon cable, so that I can
make my own panel. The leads likely carry DC OK, Halt, Restart, and so on.
Anybody have the info on this?
Thanks in advance,

Chuck McManis said speaking of EBAY:
>It sounds like this is a "bad" thing. Is it? If so why?
----- START RANT -----------------
Yes, it a Baaad thing. I was very happy when my computers were "worthless"
(to everyone else), thank you very much for asking.
1) Computers are appearing everywhere. I don't have to look so hard
any more. As a result I don't yell "Yipee" as loud any more, especially
when I realize what it's going to cost me.
2) A good portion of the discussions on this list are about what some
machine is
worth. A hobby that allows a person to gain complex knowledge of
so many aspects of their machines and it history has been reducted
to the level of baseball trading cards and "beanies". I would
rather hear about how someone just got a machine running for the
first time in 15 years.
3) I see a "Low Tech" craze coming. People will be mounting S-100 boards
to hang on the wall. Just like the people that buy old magazines,
cut them up to frame the old advertisements. By piecing out a computer
they make alot of money, and someone has a piece of Americana to
decorate their den, but it's taking technology out of context.
This will come when the prices "crash". Imagine you need a S-100 disk
controller. You find one,it costs a fortune and you need to chip it
out of a block of Lucite, because someone made it into a paper weight.
4) I don't care for the way it makes people react. The following is from
the CP/M list last weekend:

something

tolerate and

5) "Beanies" are made to be collectible. They don't have a story to tell.
They don't have a functionality that is greater than the sum of their
parts. You don't play with them. You just display them.
And that is the biggest problem. When a treasured possession becames too
valuable to use for fear of damaging it, that defeats MY purpose for
collecting computers.

Again, this is well discussed in Q16 ("Can I use the newer floppy
drives on my old machine?") of the CP/M FAQ. See

And there are several
tools - most notably Teledisk - which can handle split-density
floppies.

Anyone have any pulled MA3172s they can help this gent with or know of a
source for them? All I have are dead 8514s and I'm not good with a
soldering iron--I don't think this fella would want to buy/ship the whole
monitor just for the chip and I would destroy it if I tried to pull it.

i'd use mess-dos 5 myself. help files, and a workable editor makes it worth it
but still small enough to run from floppy.
In a message dated 98-10-27 13:58:09 EST, you write:
<<
Weeeeeeeell, I landed a Data General One laptop. Normally I eschew MS-DOS
based machines, simply because I'm a racist pig etc., but this one has an
interesting notebook mode and a built-in terminal program at 1200bps. Except
that the screen is harder to read than James Joyce, it seems like a winner
and it works great.
Question. Anyone know what version of DOS this uses? Does someone have any
boot disks out there, or at least have the system files available for
download? The drives are 3.5" DD, right?
Thanks much, >>
