Sorry, that's what they're called. ...perhaps just to keep
MassivelyWrong confused.

And other things, like "SCSI controllers". ;-)

SCSI is normally Multi-drop, not daisy chained. There can be eight or
sixteen drops on the cable. Some variants (e.g. Fibre Channel) use
other topologies (ring or switched) but basic SCSI is a multi-dropped
cable.

Big Bertha Thing china

There is an old chinese curse,
which goes "Live in interesting times."
In which times, they used to get their heads chopped off.
They used to go around saying
"Thats not so good, thats not so funny or thats not so interesting."

There was a nation of them, now some 1 billion strong.
There are even bigger numbers in OUSA Classical Particle Conf.,
such as 227879226 photons in an electron.
Every one should have one.

Hi Tony
++++++

I'm afraid you are going to have to take me through all this very slowly - I did say my
last Physics was A level some 30+ years ago didn't I?


In answer to your question, yes I'm happy to be archivist - my 486 'boasts' a reasonable
amount of hard disk space and I could allocate about 500MB to the job with as many backup
100MB floppies (on a zip drive) as is necessary. I'm a bit puzzled about the email and
password bit - do you mean that I should log on as AML34 with your password and download
your mail and files? I'm not terribly comfortable with that idea - I would much rather
you forward the relevant messages and attachments to me rather than I should find myself
reading all your mail.

Or perhaps it might be better to set up a closed subconference, one that can only be
accessed by your volunteers and I would get archive the files from there.

Or you can ask people to copy them to me or mail them to me directly.

Have a think and let me know - I would rather not mess around with your mailbox - I'm
pretty sure it's against the rules anyway!

Next
++++
I have downloaded and run the Pastures software and there are lots of things I don't
understand (probably because I don't exactly understand the physics - and I'm not even
going to try to do that right now - although I think I understand what your goal is).
First thing I didn't understand was why working through the Worked Example for Option 1 -
the seven-hour bit took my machine about 20 minutes. So either I'm missing something
fairly fundamental or there is a much bigger speed differential between a 386 and a
486DX-66 than I would have thought!

Then as Option 4 in the Worked example was next, I tried that, but it didn't work -
presumably because it shouldn't be next, it should be after Option 3?

When you refer to 'Edit particle.dat' are you referring to the Dos Edit command or are you
using the term Edit more loosely than that?

Anyway, having made a miserable attempt at running the examples I decided that I really
need my hand held on this one. I'm afraid that perhaps your documentation steps just
aren't quite small enough for me. Would it be too much trouble to go over it again at
half speed? If it would and I can't be of much help to you running the damn thing, I will
still happily act as archivist because I am now quite intrigued by it all!

Cheers for now

Pam
PS I don't understand your Big Bertha messages either - and I've heard of Serpico, there
was a not very good film made about the case a few years ago that has been doing the
rounds on Sky.
PPS: Did you ever get Philip Sims on board? You certainly managed to alienate a few mods
though didn't you? <<<Grin>>>

Cheers once more

It is a bus controller that becomes a hard drive controller per se
once hard drives are included on its bus.

Only if they are manufactured with an IDE interface. D'oh!
