The amplitude is low compared to the ring signal and it's very short blip

Max, please edit the copy string! bandwidth is limited and I can remember
what I wrote even at my advenced age.

If anybody in the UK is interested in getting this book, I saw a copy
of this recently (two or three pounds) and I'm happy to go back for
it.

I'm going to be visiting the silicon valley area and I'd appreciate any tips
on where to look for interesting old computer gear.
This is a one-time visit so if you're afraid of spreading the word around on
your favorite spots, send me email instead of posting to the list, I won't
tell anyone your secrets, I swear!
thanks,
Kai

A lot has been said about dust in hard drives, most of it assuming that
the dust is dry. But only one person (sorry, can't remember who) has
talked about other things.
Remember, not all pollutants are dry. Some (water, spittle) are wet,
and some are quite sticky (ever parked your car under lime trees?).
These will mess a hard drive up something cruel!
Yes, if you take reasonable precautions, you may well be OK. But one
day, if you haven't got a clean room, you will come to grief...
BTW, I have two questions. What does HEPA stand for? And (Christian
will parobably be able to answer this) how do you grade clean rooms? I
take it it has something to do with the size of the largest particles
you'll find in the air and/or how many of them you have...
Oh yes. I take it "Tobacco for chewing only" goes without saying ;-)
Philip.
THe site is www.pandaproject.com. The reason why your suggestion won't
work is that the drives are right in one of the corners.

The 4066/XE's belong to the US Government. From what I understand,
when an agency excesses a machine it is up for grabs by any other
federal agency, then state agency, local government, schools etc.
until it is sold at GSA auction which is where you should look.

What (tell me please) are you/they doing with the XE's as they are replaced? I
would love to get sme parts such as a Pentium upgrade board to make it a
45xx/XE
as well as drive rails, hard drives, hard drive mounts, etc and I wouldn't
even
mind considering some for purchase if reasonable enough. Sure they are heavy
but
in the process of messing with this one I thought what agreat machine for a
local church group that runs 15-20 machines and has limited funds, to be able
to
run their homeschool machines with the same software available.
I guess I ought to take this to private email as well....

Oh man! Talk about a day late... I "donated" a whole ton of Amiga

Not that I'm aware of. We are supporting a couple hundred Dell 4066/XE
Interactive Unix servers which are at the end of their life cycle and
being replaced by Compaq Proliant 2500 and 5000 servers. We have one
in-house 4066/XE for building root drives for field servers. All other
times the 4066/XE sleeps.

Marty is your Phoenix bios in your 4066/XE at A17? This is supposed to fix a
lot of
things including some sort of Y2K bug. Just installed it and it works nearly
invisible. It's on Dell's web site or FTP as 4xxXEA17.EXE

Yes, I've got it here (bought as part of a $3 per bag haul from a charity
book sale a month ago).
You are right about year and publisher, but the "author" was Bolt, not
Holt - it is part of a series called School Mathematics Project Handbooks
and A.B Bolt actually lists himself as "supervisor" of 6 Exeter School 6th
form boys who actually wrote the book.
It describes a binary adder, a NIM machine, a noughts and crosses machine
....
I see a few other replies, so that it is not all that rare :(
- but what exactly did you want to know for?
