Until just recently, either in the sim docs, or on the web page
associated with the sim, there is a table of famous landmarks
by GPS coordinates, in case you want to fly into one of them.
WTC is at the top of the list.

Hi,
If there are no other (or nearer) takers for

there is sufficient interest.
Obviously I'll pay for shipping (surface mail).

The only reference within TI's own site (that

freetradezone has a two page sheet which
has little technical information. It does say
that software simulators were available for
customer use as were hardware simulators.

I purchased a plastic bag mixed with new and used 5 1/4 floppy diskettes
and inside the middle was one of the famous "Fileware" or Twiggy
diskettes with it's sleeve used with the Lisa I. I could not believe
my luck as I had just watched one of these go for almost $50 dollars on
eBay for just one diskette awhile back. Now I just need to find a
twiggy drive or better yet a Lisa I. :-) Yes I went back to the
thrift store looking for more disk but no luck. The cost of the package
was $1.40 for about 20 diskettes.

Yeah, phone net was designed with the idea that you would piggy back it
over your existing phone wiring... the theory being that a standard
house/business would be wired either all serial (one jack to the next) or
in a star (all jacks coming back to a central punch block). Following
this assumption, it was specifically designed to work over the unused
pair (being yellow/black in standard station wiring).
All PhoneNet REALLY cares about is having two wires from one box to
either the next box, or to a central hub. It need not be twisted pair,
and it need not be the yellow/black pair. Although, if you choose to use
a different pair, either you need to make sure you wire it to the correct
pins on the jack (and thus fake a y/b) or you will have to cut a custom
wired flat cord as the boxes all expect the wires to be the outer two
wires in an RJ-11. But there is nothing stopping you from using unused
pairs in Ethernet and just use a custom flat cord (or break them out into
their own jack).
The single biggest problem with Phone net that I ran into was it was VERY
picky over the wiring being correct. Unlike phones, you could not safely
reverse pairs in a serial setup. Also, the fact that it expects there to
be either serial wiring, or star wiring falls thru in most phone lines.
And even depending on the unused pairs wasn't a surefire idea. In every
Phone net system I installed, I was forced to do some degree of rewiring,
or correcting the wiring. POTS phones are very forgiving to poor wiring,
and many telco installers use that as an excuse to be lazy. In almost all
POTS phone setups you will find some degree of "non spec", things like
unused pairs not being connected, reversing pairs, mixing star and serial
wiring, tapping mid line into a drop to extend for a new jack. Tapping
was DEATH to phone net, it was the single worst thing you could do, as it
caused things like ghosting (items showing up after they have been
removed, or showing up more than once on the network), and random
dropouts of networked devices. It also proved hard to track, as you
almost had to physically trace every wire, looking for a tap.
But all things considered, phone net was a much more econimical way of
wiring a localtalk network. True localtalk cables were very expensive
compared to cheap 2 pair phone cable, so even with rewiring, it still
worked out to be the less expensive way to go.
Even today, phone net works as a nice quick and dirty network when all
you want is printer sharing. I keep a 25ft retractable cord and phonenet
connectors connected to a Localtalk to Ethernet bridge. It lets me
connect old Macs to the network (or my Newton) on the fly, and I can set
it up anywhere in my office. When I am done, I just unhook the phonenet
box, and let go, the retractable cord rewinds and pulls the box back to
my hub shelf, where it hangs waiting for my next use.

That seems very likely, given that it was invented by AT&T in the late

I think I still have mine, and in working condition. Although I would not
be willing to part with it (thus why I think I still have it), I CAN open
it and send some digital pics of the chips. Maybe even draw out some
schematics.
I would guess that based on its age, there is nothing fancy in there.
Probably a simple eeprom or something for storing your stats, and
everything else was probably random gates (fighting, spinning,
whathaveyou). As far as "emulation" goes, I would think you could just
write it from the ground up following the rules of the game. Although, it
wouldn't be a true emulation, it would make it playable (and you could do
it networked EASY... now THAT would be a cool internet based game!)

That's true, you can run all sorts of things over Cat5 "structured wiring",
in fact that's the point of structured wiring. 10baseT uses two pairs
(pins 1+2, 3+6), the phone uses the centre pair (pins 4+5). ISDN uses all
four pairs.
Serial lines use either the middle pairs (for Tx/Rx) or all four (DTR/DSR,
Tx, Rx, RTS/CTS) if they follow the DEC (and other) system. Some use the
same pairs as Ethernet (which means a crossover cable for Ethernet also
works as a null-modem for Tx/Rx on serial lines).
100baseTX uses the same pairs as 10baseT.
You're not supposed to run a phone line (pins 4+5) on the same cable as an
Ethernet (pins 1+2, 3+6); it breaks the spec. However, you'll normally get
away with it with 10baseT, and it *may* work for 100baseTX over short
distances. It certainly won't work for 100baseT4 (does anybody still have
any of that?) or 1000baseTX (Gigabit) because they use all four pairs.
Nevertheless, you can buy little boxes which are essentially a Y-piece for
phone+10baseT -- you need one at each end of the cable. They consist of a
small box with two RJ45 sockets and a short Cat 5 lead ending in an RJ45
plug. You can also get similar boxes to combine/separate two 10baseT
signals (they move the second signal from pins 1+2 and 3+6 onto 4+5 and
7+8) and ones to simply double up the sockets (pin 1 to pin 1 to pin 1; ...
; pin 8 to pin 8 to pin 8) which are sometimes used for ISDN. For some
reason they tend to be different prices, and all overpriced (over here they
cost ?8 - ?15, though you can make one for about ?3 including the cost of
the box to put the PCB in).
I'd be wary of running Localtalk over a cable carying a phone or Ethernet
signal. Again, it might work, but it will probably generate interference
which might be hard to track down -- I write from experience[1]. Better
to use one cable for one service at a time. The real reason for using
different pairs for different services is partly serendipity, and partly to
avoid damage if you plug the wrong device into a cable which is already
connected to something incompatible at the other end.
In my workshop and study I have quite a lot of Cat5 (actually Cat5e, the
Cat5 standard is officially obsolete) which I use for 10baseT, 100baseTX,
serial lines, ISDN, a phone line, and even the audio to the speakers. I'm
about to add a couple of Econet adapters, and I'll probably use it for some
LocalTalk (PhoneTalk) when I get round to sorting out the non-Ethernet
Macs.
[1] More than one bad experience, but exemplified by the occasion when I
had to make a trip to Northern Ireland with a couple of technical staff
>from Acorn to visit some schools who had networking problems. The school
staff insisted everything was done to the standard, but it turned out that
their erratic network problems were due to putting LocalTalk down the
existing network cables. It had worked for a while, but when they extended
the networks, both suffered.

A few pics of the controller to Dark Tower have been posted. You can find
them at <http://www.mythtech.net/darktower>. (Pic #28 is missing, it is
the same as 29, just out of focus).
The board is about 7" x 3" (17.5cm x 7.5cm) There isn't a whole lot on
it. 3 lights down the middle that are socketed, an LED digit display, a
pair of LEDs (IR send and recieve, it is used with the picture disc to
determine what pictures are facing out), there are a handful of
resistors, a few Capacitors, 3 transitors (9112 D 07; 9113 D 05; NP2
3704) a choke coil, 2 diodes, and 3 ICs.
The 3 ICs are all Texas Instuments, photos of them are on the web site (I
made sure you could read the numbers, but they are upside down right now)
The two connector looking things on the very end of the board opposite
the LED digit display... are in fact connectors. The white one tied to
the motor, speaker, and batteries, and the black one tied to the push
button panel for user interaction (the push buttons are a flat 3 x 4
pressure panel connected to the board by a ribbon cable.)
That is about it. I will try to draw up some basic schematics later (I'm
a little busy at work right now, hopefully I will get to it later this
week, or maybe next week).
I don't know if I will be able to do any testing of my unit. When I
opened it I found batteries had been left it in, and leaked. There is
some pretty bad corrosion of the largest IC where the battery acid
dripped on it. I am hoping it will still work when I clean it and put it
all back together, but there is a chance it has been damaged. Also, the
LED digits have suffered some damage (the laminate cover is peeling back
>from corrosion)
I will post again when I have the schematics done.

well, it has been a while since I looked at one, but if I understand you,
you want the big black external brick that goes between house current and
a small round power plug on the PCjr... right? That is what I think I
have one or two of still kicking around.
The one I was picturing in my mind (and why I was thinking of an odd
right angle plug), was a power brick to an old HP Deskwriter... I
realized that about an hour ago, when I kicked the HP brick that was
sitting on my floor.
Now, the problem is, I might have been thinking of the HP brick when I
was thinking I might have a PCjr power brick... but I will still look,
just to make sure. (If I have a PCjr one, I know where it would be, it is
just a matter of getting to it)

Well, I bought a membership and expensed it out to $CURRENT_EMPLOYER, and

There is one motherboard seller selling refurbs, clearly marked, and
ditto as maybe or maybe not functional. But a few things do carry a
warranty, and I see the same faces and company names almost every time
(especially the non-hardware guys like Hacker Hut). At least 50% of the

Good thought, but it's not quite that easy. As I recall, AIX defaults to
the JFS file system. This is an IBM proprietary, journalized filesystem,
and would not be trivial to "write a utility" to safely modify it. Standard
Linux (or any other Unix, for that matter) will not recognize it.
Luckily, there is a Linux port of JFS (http://oss.software.ibm.com/jfs/). I
dunno if it will mount a native JFS filesystem from a legacy AIX box, but it
should show you what you need to do to get started.
Oh, yeah...AIX stores passwords in /etc/security, or somesuch odd directory.
Wants to be a TCB, but isn't really a TCB.
I liked and respected AIX...but then I didn't pretend it was really Unix.

They do tend to be high, new Americans seeking their fortunes... but
a few people carry surplus stuff, and it tends to be priced better if
it isn't so decript as to be not worth buying (but perhaps worth picking
up off the trash pile).
I picked up VB 5 Pro a few years back for $50, and VC++ 5 for the same.
But one vendor screwed me out of a academic VB package that came with NT;
he had it priced for $50, I made the mistake of asking if it was for real,

Since I didn't know the answer I asked someone
who was a Philbrick employee from 1949 to 1966.
"Hi, Doug:
The standard rationale was that the purpose of the
spelling was to differentiate between
machines that did computing and people who were
employed to do so. For example, my wife's roommate,
in the early days of her post-college life, had a
math degree and was employed at MIT's Whirlwind lab
as a "computer", doing computing tasks that were too
complex for the digital machines then existing.
However, I think that George really invented the term
(a) because it was attention-getting, (b) to
differentiate his product from the competition,
and (c) because he always liked to do things a little
differently and more creatively than the next guy."

Wow, even a users group! This is great.
The boards are beautifully done, discrete logic, and dipped in a conformal
coating. Each transistor or diode has its own serial number, which I assume
provides traceability to quality control. The card cage is cylindrical, and
surrounds where the "stabile platform" would go, except they were removed
before the computers were surplused, for reasons of secrecy. I heard once that
the whole thing cost about $1/2 million, half for the computer and half for the
stabile platform. There is a port in the card cage where a telescope on the
stabile platform gets to look out at something, presumably the sun or stars.
Thanks for the info,

Hello All,
Please respond privately.... this is going to two lists.
I have a Micro PDP11 that I would like move to a new home. It is an
11/73 that uses the CPU board from the 11/83. It is the 18mhz J11 CPU
with FPU (M8190-AE). It currently has 2megs of ECC memory, although I
have about 3megs worth of parity that could be swapped in instead.
Various other boards are included (no scsi boards :-) It is in the
tower mounted BA23. The case is clean, but has a few flaws....
scratches and the base is cracked, and one of the little horns? where
the back cover fits it cracked. Overall the case looks very nice. The
steel chassis itself could use a vacuum, However.
I could get into he ROM with a terminal, but never got it to boot from
the RD54 HD. It complained of a bad controller (m7555). I have spares,
but never tried them. It could be the drive as this particular PDP11
has a bad history with drives according to the documentation that came
with it.
The main reason I would like to move this on, is because I don't have
the time to learn about it. I know nothing of the PDP11 OS's. Plus I
have a Vax that I would like to get working, and lots of other little
projects.
In the subject line, I state "almost free". I do have some money in it,
and would like to recoup at least some of it, so I'd like to get $40 for
it. That's certainly much lower than what it would fetch on Ebay.
I live in Battle Creek, MI. It's right off of I94 about 1/2 way in
between Detroit and Chicago.
Here is the info on the cpu board from the field guide:
M8190-AE KDJ11-BF Q/U 11/83-84 CPU J11 CPU 18MHz with 2 boot &
M8190-AE diagnostic ROMs, FPJ11-AA.

>I'm thinking that the drive might be going bad.
If it doesn't boot when you first turn it on, you might not have let it
come up to speed fully. It takes a good 20-30 seconds to come up to speed
before you can turn the mac on. The drive light will turn on, then start
blinking steady, after about 20 seconds, you will hear the drive click a
whole lot, and the light will blink rapidly for about 2 seconds... after
that, it is up to speed and safe to turn on the Mac and try booting.

It was through the floppy port. It used a special boot disk with a

In spite of the now long-extant senility, I seem to recall that these

True. Despite development over 40 years, witness the recent death

fine, it's the fuel tanks that we still don't know how to build...

The card has trouble with high transfer rates. The on-board
BIOS allows you to limit that to 5MB/s; when I slowed it down
to that, it worked fine for me. YMMV (rather, HMMV), etc...

I was almost 100% positive that I once had it working on a 128k, but a
search of apple's TIL shows that the HD20 works with the 512ke, Plus, SE,
Classic, IIci, and Portable... so I guess I never took it lower than my
Plus (I never owned either of the 512's). This is going to be a head

There are two different products with the name Hard Disk 20. One is the
Apple Hard Disk 20 SC and it is a SCSI device. There were also 40, 80 and
I think 160 mb versions (and maybe others in larger sizes).
BUT... predating that was a "Macintosh Hard Disk 20" that was not scsi.

I have seen the boards out of one of the minutemen missile computers. IIRC
they are very interesting Boards composed of discrete components. Anyone who
has a full computer is very lucky. I would consider it to be an extremely
rare collectable.
The Boards that I saw were about 4"X6" and heavily plated in gold then
lacquered. They are very pretty. I would love to see a whole computer.

Astoria, OR
I don't think the one that he's talking about is SCSI, it plugs directly
into the floppy port on a Mac 128k or Mac 512K. ISTR, using one on a newer
Mac Plus instead of a SCSI drive as I needed something of that formfactor
and that was all I could get my hands on at the time.
Based on how it's used, I'm guessing you're right about it being a MFM
drive, but I suspect it's some wierd sort of bridge in it.

Anyone have one of these in use and could possibly be a source for a copy of

software and this is NOT SCSI to the server, it works on the LAN and has
SCSI drives in it. Even if someone can send me the manual so I can scan or

Subject: Re: Burroughs E6000
As late as 1977 ! was using two Burroughs E6000 computers to perform the
function of loan payment application. The loans were for health club
membership in the Chicago area and a great deal of the rest of the upper
midwest area. We had over 50,000 loans outstanding at any time and
processed from 1,000 to 3,000 loan payments a day. The machines we had were
magnetic stripe ledger card readers and they would punch an output card
with the results of the processing of the transaction. The latest
information about the loan kept on a master deck of cards was replaced with
the card that was punched as a result of the transaction on the E6000. The
update was performed on a daily basis using the 085 sorter and a
reproducer/collater. During the last 8 to 12 months of the use of the
E6000, while a conversion was being worked on, we used only one E6000 and
kept the other one for spare parts. Burroughs had run out of spare parts.

Not to double reply... but now I am going to start beating my head into a
wall.
Apple's technote article # 8169 (in the archives section), claims that
the only way to add a hard drive to the 128 and 512 is by using the HD20
non-scsi drive (the one in question here). This seems to contridict a
previous technote that lists the first supporting mac as the 512ke.
So now I am REALLY going to have to pull out my 128 and see what
happens... it seems Apple doesn't even know which way it goes.

I guess I will have to keep an eye out for a SCSI board for the IIgs.
Maybe I can also track down an original Apple HD SC... just to keep

It was the second generation before really complex LSI actually the '181
was
likely the highest gate count part in the class before the TI bit slices
(74881-884).
It's also very old but still a handy part as it does all the standard
arithmetic ops
and logical ones too. The ALU core of the 2901 is basically the 74181.

Why not. they were demil'ed and made available to colleges and
any one else that could deal with the 30someodd inches diameter
by 20 inches tall "slice". It wanted three voltages and one whole
whopping amount of power. PITA to cool as well. I'ts been 30 years
since i've seen/played with one.

Maybe. The 'T' in "10baseT" etc is the same 'T' as in "UTP" -- unshielded
twisted pairs. I don't know what the 'T' in "T1" stands for. It might be
the same as one in "AT&T" since they coined the term, or it might mean
"twisted pair" because that's how T1 lines were originally made. T1, BTW,
is 1.544Mb/s, and T3 is 44.736Mb/s; AFAIK there's no such thing as T2. A
bit like ISDN; there's ISDN2, ISDN6, ISDN30, but no others.

Sounds a lot like a box I've been threatening to build for a while.
On the Ethernet side, I'd not worry about specific 10bT and ThickNet
segments. Instead, I'd run a single 10b2 (ThinNet) segment and get a 10bT
hub with a BNC uplink. This also had the advantage of saving you a slot in
the box. Don't worry about ThickNet, just pick up a couple of spare 10bT or
10b2 tranceivers for the odd box with an AUI port.
Since you've got LocalTalk running to the box, then I'd also run MacGate
which would let you run MacIP (IP over LocalTalk).
As for other fun topologies, you already mentioned TokenRing. My personal
choice would be to also add HomePNA (Ethernet over phonelines). The 1MB
HomePNA 1.0 cards (the only ones supported by Linux)are very cheap these
days. I picked up a pair from Computer Geeks (http://www.compgeeks.com) for
something like $12. Now if I could just find a cheap Ethernet/HomePNA bridge
for the Nubus Mac in the spare bedroom...

Subject: ArcNet and the Pursuit of Multiple Topologies
Dear all,
I've decided that one of my goals is to run every networking topology
possible in my house, regardless if I actually NEED to run them or not. :)
My plan is to place 1 linux box running a card from each topology in it and
use that to bridge all (or almost all) topologies.
I currently have running 10bT ethernet, 10b2 ethernet, Localtalk over
PhoneNET and the beginnings of Arcnet.
In light of such, I have a series of questions:
1) Who knows some stuff about ArcNet? I've gotten 4 cards (8-bit ISA) and
a
16-port active hub. I've read somewhere that cards are either hubbable or
not. Any other info on that?
2) Anyone have any (I think it is) 93ohm coax arcnet patch cables that they
want to get rid of?
3) Anyone got good resources on ThickNET? (10b5 I think it is?) I know it
was run back in the day, and I know some precursory things about it (the
funky vampire taps, etc.) Anyone have either resources or hardware on this
topology that they'd like to share/sell/etc? :)
4) Any other interesting topologies I should try? I have plans to do:
Arcnet, FDDI, Token ring, Localtalk, 10b2, 10b5, 10bT, 10bTX, 10bFiber, and
(eventually) 802.11b wireless.

>8-)
Well, if the original poster was refering to what I had, then Dark Tower
is a board game (circa late 70's early 80's). The board was this roundish
board that you moved all over, and there was a dark brown plastic castle
thing that sat in the middle.
The object was, you were an adventurer, and you had to move about getting
things (treasures?) from each land (4 lands, 4 players IIRC). When it was
your turn, you would press a button on the tower (I think there was
"pass" for do nothing, "move" to go somewhere). It would then spin (well,
the inside would spin, the tower stayed still), and eventually stop,
telling you if you ran into enemy's, or treasures, or whatever. If it was
an enemy, you had to fight them, and it would track your possestions and
army strength, and would tell you how you did (how many people died, how
many of the enemy joined your ranks, if you got new possestions)
Basically, it was a 4 player, board game version along the lines of D&D
(and was out when D&D was in its hayday, something else I am afraid to
admit I was in to.).
I would be happy to pull mine out (I am sure it is in my parents basement
still, I have to go over there today anyway to fix my mother's computer),
and I can take some pics of it, and scan the directions if people want.
Of course, maybe the original poster was refering to some other Dark
Tower game, and I now look like a total ass (but the one I know of was
really cool, so even if I just get to tell others about it, it was worth
the typing).

An ALU isn't that complex, really. Find a TTL databook and look at
the logic diagram of a '181. There's not that much to it.
More complex and less "generic" than a 7400 quad NAND gate, sure...

Tony,
According to a datasheet downloaded from www.freetradezone.com (free
registration, and supposedly 12 million component datasheets -- I believe
it, as there's yet to be a part I haven't found)....
It's a CMOS 4-bit magnitude comparator...
1: B3
2: (A < B) IN
3: (A = B) IN
4: (A > B) IN
5: (A > B) OUT
6: (A = B) OUT
7: (A < B) OUT
8: VSS
9: B0
10: A0
11: B1
12: A1
13: A2
14: B2
15: A3
16: VDD
I can email the datasheet if you'd like.... It's a 220KB .PDF file...

This last weekend I pulled my old rack mount
CompuPro system out of storage and cleaned it
up. The last time I used this system was about
15 years ago and I only used it to edit my resume
in Wordstar.
The system consists of:
a "CPU 8085/88"
a "DISK 1" controller
a "SYSTEM SUPPORT 1" for the console
two "RAM 16" boards for a total of 128K
and two Qume 842 8" floppy drives
After one small capacitor fire I had the system
up and running. I went through all of the 8"
diskettes I could find to determine what would boot.
So far, I have bootable disks for CP/M 2.2,
CP/M 86, and CP/M 8-16.
But the disks that I really want to read are in
86-DOS format according to the label. I have
disks that claim to be 86-DOS boot disks but
they wouldn't boot. Some of these disks I'm having
problems with appear to be SSSD 26 sectors/
128 bytes if that helps.
Can anyone point me in the direction I need
to go in order to be able to boot 86-DOS?

some other snippet?

After finally getting my TU56/TD8E setup operational, I now
run into problems generating an OS/8 system tape.
The system keeps insisting that "TAPE #2 is not an original dec tape",
although i know for a fact that it is.
I have 3 sets of system tapes and all generate the same error.
Tape #1 is never asked for, the resulting tape is of course not usable.
Any clues what I'm doing wrong ?

Sorry to be late to this topic. As it happens, I've got a DEC 3000/300X
(175MHz 21064, 64MB RAM, 2x2GB Disk, NetBSD 1.5.1 + fixes) in production.
I'm fond of it, but probably more for the fact that it comes in a rackmount
sled, which appears to be quite rare. It fits nice at the co-hosting
facility (it's www.thistle.com, but it doesn't talk to anyone but me right
now).
What I know:
Memory: No...you can't put just anything into it. It's got 8 72-pin SIMM
slots, but it will only accept 8MB, true parity, generic SIMMs (giving
64MB). And it's damn finicky about those. My 3000s spits on SIMMs that
everything else in the basement has no trouble with. It will also accept
Digital custom 32MB true parity SIMMs (giving 256MB). Nothing else that
I've found will work, but that could just be me. If anyone has any of these
SIMMs they don't want, do let me know...
Video: AFAIK, none of the free *nix systems support the built in TC frame
buffers. VMS and OSF/1, nee Tru64 do. The 3000 will run X clients and
display to another machine. Real men do serial consoles anyway.
Speed: Slow. Really slow. Not PC532 slow, but not something I'd trade one
of my PPro 200s for (other than the swanky rack-mount sled). Definately
useful for low volume web, mail, etc., but "make build" isn't pleasant. My
PC64-275 is way, way faster, but still not that fast.
There's lot's of good info out there, and I know there are people working to
support all that isn't currently supported. Drop me a note if anyone wants
to know anything else.

The stringy floppy is flawed the same way an 8-track audio tape is -- it
only moves in one direction. As a result, A&J didn't write any OS for
their drives, just a couple of simple commands. You search for the file
you want, and you either find it (after several minutes) or you don't
(after several minutes).

Ahh, neat! I've heard a bit about Wang VS systems, but I had no

74LS181 is 4 bits wide...how many does it use?
Have you had a chance to take pics of this system? I'd be highly
