That does have rhyme & reason to it -- yes.
(And you are correct in that it takes 2 of these 2.5V lithium cells -- I
failed to mention that in my original post.)
I suppose it just couldn't have been foreseen by them that SAFT would
discontinue manufacturing this particular battery at some point down the road.
Still, though, wouldn't manufacturing a device which relies on a sole
provider for its power cells raise a flag or two during the design process?
It is not like these batteries are as common as dirt -- like your typical
Duracell "AA". (Then again, I'm no hardware engineer, so I'm not familiar
with how these decisions are made.)

Yup, that is exactly the kind of law it is. It really isn't enforced by
itself (they don't round people up for owning lock picks), it is just
used as an aid to arrest/detain someone that you have a really strong
hunch is up to no good (and as a way to confiscate the tools from someone
that you are sure plans to use them to commit a crime... this is done in
inner city schools when kids pass thru metal detectors and are found to
have various items that have perfectly legit uses... but you know the kid
doesn't have it for one of those reasons... box cutters are the most
common item)

Where are the young people on the list ? ;-)
I'll turn 23 in a month and have been working on oldish and "cool" computers for approx. 7 years now.
Started with a Philips P3200 (286, heavy stuff) which infected me with the bug...
I can't talk of nostalgia as my machines are mostly from the time, I couldn't walk yet... DEC and CDC stuff,
but also some SUNs from the time I started going to college.
There's also stuff before I was born, like my PDP-8/a. It's funny to think about that.
As adrian said, nostalgia from my time would be 386 and 486 and so on, which obviously aren't very interesting to investigate time on. Moreover, there's nothing you can repair on these things by yourself...

Ok, I can do that. But bear in mind that providing for a particular persons
mailserver to have an extended outage, means that because of YOUR outage, 14
other people won't get their email for a while. How far do I try to
accomodate one person at the expense of others?
I'm still considering options....
----------------------------------------
Well, if I had been one of those 14 people today it wouldn't have mattered;
as a matter of fact, *my* ISP (a public commercial ISP in a major city
(Toronto)) was down for most of the day today while they moved their equipment.
Even two of our major banks had their respective Canada-wide credit card
& on-line banking networks go down for almost a day recently, so it does
happen to the best of them.
But I understand your problem, and BTW, let me join the list of people
expressing their appreciation for the time & effort you put into running this list.

For the record (no pun intended), I have no MX record at all. They are

[This post involves a hand held lab computer, of which this particular
model was made/purchased about 15 years ago. Similar models have since
been made, but without the problem I describe below.]
I have a hand held lab computer (manufactured & purchased in 1990) which
takes quite an unusual battery.
The battery is the size of a regular "AA", but is 2.5V Lithium. The
company who used to manufacture them (SAFT) no longer does so. The SAFT
battery model # is "LCP 6".
Picture of battery (and a regular "AA" for comparison):

Picture of lab computer:
http://home.san.rr.com/instep/labpartner-front.jpg (~58KB)
http://home.san.rr.com/instep/labpartner-back.jpg (~44KB)
The company who made the lab computer still offers to refurbish the unit
for a new (more readily available) lithium battery pack, but I want to
avoid doing that if at all possible. They also don't have any suggestions
as to where to find a 2.5V Lithium "AA" sized battery.
AND -- I've Google'd high & low for an equivalent, but nothing pops up.
So I've come here to ask: does anyone know if an equivalent battery exists?
(And what's with the designer(s) decision to use such an obscure battery type?)

It might not make a perfect solution, but you could take 2 nicad cells
(1.25V each) of similar diameter and a shorter length (N size?) and
place them in series in shrink tubing to make a replacement cell.
Also check out the oddball batteries available for photo equipment.
There's a lot of odd voltages in that category, though you might have to
slightly modify the cell holder (widen it a bit).

Again, who gave you the right to dictate so? Yes, as the sole owner of
Harhan Engineering Company I of course have total control of the Harhan.ORG
and Harhan.COM domains, but why in the hell should I spend money on a
backup server just because YOU decree so?
Many many many original ARPANET sites did just fine with one single mail
server for the organisation. It was a Classic computer, like a VAX-11/780
running 4.2 BSD UNIX, or a FOONLY running TENEX, or whatever. They were
kept up diligently with tender loving care, just like I maintain my VAXen,
but boards DO go bad sometimes, and PROPER hardware troubleshooting (the
kind that Tony Duell practices) takes more than 35 min.

So, let me get this straight; as long as the client is running on
a 386 or older (even though the files are dated 1996) it's on
topic, but if someone were to ask how to network a Pentium II
running DOS 6.22 to his XP system, you'd presumably tell him to
FO & get the files from Microsoft; have I got that right?
<rolling of eyes & shaking of head>
BTW, does your package include the addon to make it bidirectional,
or is it one way only?
I've used the MS client for years without any hiccups, but it is
VERY memory hungry. It IS free though...

Depending on where you are, owning a lock pick set may be illegal if you
do not have a reason to own one.
Last I knew, lock pick sets were illegal to own in NJ unless you are
someone that has a "legal" use for one. Of course, since legal use isn't
really defined, it leaves it pretty wide open. (It is also illegal to
have a police scanner in your car, as well as carry a center punch...
again, unless you have "legal" reasons for the above... of course, being
a volunteer firefighter seems to get me past the legal requirements for
all of the above... so naturally I own all the above... and carry a
center punch in my car most all the time, as well as a lock pick set in
my tool bag)
Of course, IANAL, and I could be mistaken on the laws, or the exact forms
of them... but it is a heads up for those that may be planning to
purchase a lock pick set and run around with it in their back pocket...
they should just verify that they are allowed to do such before they find
themselves being accused of being a terrorist ;-)
