Are you sure it would destroy the floppies, I dont' think so, I think it just
looks at them to check that you own them.
Windows95 demanded that the DOS floppy not be write protected and trashed
it so the DOS on it won't ever install again. I assume that ME would do
the same to the Win98 floppies and am not about to switch off the write
protect to find out.


I have my previous Windows on CDRom
so it couldn't destroy that. If microsoft was going to destroy your floppies
I'm sure it would tell you first. And you could just make coppies of your
floppies anyway.
Copies of Win98 install floppies will not install Win98. There is some
thing non-standard about the Win98 floppies.

Have you looked at your bios settings. I've sometimes had to tell bios that it
is not using a Plug and play aware operating system to get Me to run OK. In
this case the bios routines set the addresses and interrupts and not ME.
I've tried both "plug and pray" on and off. It is currently on.

Good luck, I'm still running ME, with good results on 6 computers. The geat
thing is that no one is bothering to make new virus for it.
You can still get hit if you run outlook and have any of the windows
office stuff installed. The virus checkers don't check for all posible
bad macros. They check for the ones that have been seen. If someone
writes a new macro exploit, it may get you.

Do not ask me why.
I will not reply to questions.
You also seem to ignore what was said, or failed to understand it. More likely

Your past misconduct tells me that no matter what is said you have a lame

Yes, this should be possible. In fact, I heard about one device that

I find this difficult to believe for modern modems.
The bits are simply too fast, and to make them visible all recent modems
that I've seen have some sort of pulse-stretcher to make them more visible.

I was just cogitating earlier on the TO-92 package for UHF devices.
Often these are also available in surface mount, which is obviously
better for the higher frequency limits of the device in question.
Given that zero lead length is the ideal with through-hole, is it
practicable to scuff away enough of the top side of a PCB (with a
dremmel) where the device is to be placed to reduce the board
thickness down to a few mil and thereby eliminate a small amount of
stray lead inductance in the process? Is it worth the effort for the
minimal amount shaved off?
No. What I have seen is cutting a hole in the board and placing the
tranny sideways in it, then solder the leads to the pads. I that case
it was to shave off a bit of overall thickness but should work for
other purposes too.

TCXOs have to sweep a wide temperature range and all crystals have small
purturbations over temperature due to unwanted responses. An OCXO
crystal sits between the temperatures that give purturbations.
There was an emergency beacon that employed a crystal under the armpit
to maintain close temperature control.
I could envisage other constant temperature locations.
An SC cut matched to the individual could meet your requirements.

Interesting then that the dictionary definitions you so kindly provided

Yes, that's dictionaries for you. They should be barred from defining
technical terms that they don't understand.

Axioms DO NOT have to be self-evident. In fact, in my post about non-
planar geometry I gave two examples of Fifth Postulates that are very
far from self-evident, and are incompatible with each other and with
Euclid's, yet all three are valuable.

In Chambers Dictionary, the Witch of Agnesi equation is given as

x^2y = 4a^2(2a-y)

A little algebra results in the far simpler form:

y = A/(1 + X^2), where A = 2a and X = x/A (i.e. the x-axis is just
linearly scaled. Before your jump all over me, there are a number of
other forms of the equation, all equivalent.

You can state ANYTHING as an axiom if it is internally consistent. But
not all axioms are useful. Some sets of axioms define Universes other

Hi John,

I use AutoCAD.



Can we call you 'Mr. Moneybags' in future?


I remember AutoCAD came out with a small low-end program that cost, I
believe, under $100. It won't likely suffice to design a bridge or an
engine but it should be enough to create a meter.

Why not start with a passive divider, thin-film or something?
The capacitance of widely-separated electrodes is asymptotic to the
free-space value. This means the capacitance may be very much larger than
calculated from standard formulas. Here's an analysis of the field lines
on widely-separated circular plates. See the section at the end, titled
"Plates relatively far apart":

"As the distance between the plates increases even further, the
ovoids become increasingly symmetrical, until they approach
ellipsoids. In the limit, the plates cease to interact at all, and
each plate holds a charge based only on its potential with respect
to the surrounding space. Thus, as the equipotentials approach
ellipsoids, the capacitance approaches a constant value that is
independent of further increases in plate distance."

http://www.ttc-cmc.net/~fme/captance.html

So a thin film resistor may or may not reach the ~0.05 pf stray
capacitance needed. I tried using a 2D field solver, but ran into the
problem of accounting for the fringing fields off the sides of the
contacts. Obviously the problem is solvable - both companies did it. But
it's not clear how.

A small PHEMT might have Cgs of 0.2 pF (naked chip) and Cgd even less,
so it doesn't sound exotic... just a lot of hard work to keep the
response clean.
Agree - solvable, with a lot of effort. Of course, you need the toys to
play with this stuff:)

I still think a dual-gate mesfet follower could be a neat, cheap
active probe. Bootstrap G2 and the input resistor, and servo it to
Idss to kill the offset and LF dispersion. Some of the available IC
buffers/followers would make a pretty nice probe, too.
2 to 6GHz is easy. We need a minimum of 20 to 30GHz bandwidth to handle
Gigacom, plus any exotic stuff you might come up with:)

Mike Monett

How? A third "modem" listening somewhere between the two modems will
need a a method to separate the signals from the two modems. The two
modems can do this as they know what they send and has trained their
echo cancel algorithm during the initial connect. The third "modem"
can't use this method and will have a very difficult time listening to
the traffic. I have never heard of any equipment that can do this, but
it is possible that some government funded organization have designed
this kind of equipment...

I don't have much experience with JFETs, but bipolars will detect IR
straight thru the plastic package, even when properly biased.

TI used to have a line of IR photo diodes that were just like the "D"
plastic BJT package... no windows ;-)

Well, yes.
Sniffing anything is possible, V90 is a bit harder than V21, as you've got
to split the line, and work out the echo cancellation that both modems
are doing.

In nearly all cases, doing a modem-in-the-middle attack is going
to be easier.
