Actually, this is wrong.  PowerOrgasm actually plays the sound when
the powerplug is inserted into a PowerBook.  (I think the symbolism
of this should be obvious to you.)  So the extension will only work
on a PowerBook.  But boy does it work.  ;)

The SndControl cdev (part of the Sound Utilities Package recently posted
to sumex-aim) also provides this feature on PowerBooks.

cisco monitors the cisco newsgroup, in practice and probably in theory
too. They CERTAINLY respond officially to e-mail. And I'm very glad they
do, in fact it is one of the reasons we continue to buy their equipment.

With an 18h time difference I find e-mail useful in ways that snail mail

Maybe one of your inits or extensions is expecting you to do something

reason 1:  I am one of those people who communicate better when I have a
chance to edit and reedit (and sometimes just forget it).  If I can send
e-mail the signal to noise will be higher than if I make a phone call.

reason 2:  E-mail is 24 hours and has no "All our representatives are
currently handling other callers, please stay on the line...".

reason 3:  E-mail is something that exists, that you can come back to and
reread, whereas a phone call is a one-shot deal.

reason 4:  1-800-555-1212 (Toll-free directory) doesn't have any listings for
Apple Computer.

reason 5:  I've called the 1-800 number.  

Incidentally, I've talked to the local IBM reps by phone, and I wished
that *they* were selling Macs instead of horribly inferior machines with bad
software.

I end up feeding the F4AC value on the BSR to the CPU as an instruction.
In short, I got branched to 40810000. A little address arithmetic gone

This means somebody dereferenced NIL and tried to execute it as code. 
Usually the result of not checking for errors after GetResource calls.

Dereferencing NIL is a common programming error, so the boot code in the
system puts a ROM address at location zero.  This way, if someone
dereferences NIL and then writes data, they'll be writing to the ROM
(instead of hosing RAM).

<begin shameless plug>
A utility I wrote called EvenBetterBusError helps programmers find these
errors during development (perhaps "Greg of the buttons" could use a copy).
 EBBE puts a "nasty" number at location zero.  This number causes a bus
error if accessed as an address, can't be jumped to (because it's odd), and
is an illegal instruction (in case someone tries to execute code at
location zero).  EBBE also watches to see if code writes data to location
zero (another common programming error).  EBBE is on ftp.apple.com, and
probably a few other places on the net.

This must be one of the most fundamental question on System 7.    Recently, I p
urchased a PowerBook 100 which came with System 7.0.1.    I have been using sys
tem 6.3 on my Mac Plus and cannot figure out how to load DAs such as Expression
ist, Wordfinder so that I can use it in Word without resorting to multifinder.

Putting them in Applemenu does not seem to work.    Also how do fonts get loade
d.    When I opened Expressionist and tried to change fonts, there was no fonts
 loaded.

Another simple question.....   Can I operate PB100 with System 6.3 which does
not have the battery check or sleep function.

If this doesn't do it - another option is to just *wait* a bit.  A
screenShot of a large/deep monitor (or more than one of them) can take
quite a while.  First, you'll hear the camera shutter fire, then the
mouse will freeze while the shot it taken.  This can take up to 30-60
seconds - depending upon your HD speed and the amount of data.  If you are
impatient (like many are) and think the machine is hung and reboot it, this
may be your only problem.

I personally think FKEY 3 should have made a "click" noise, and then
make the shutter noise when it is all done.  But then again, maybe
it isn't that important... :-)

It isn't neccesarily a strange time to do this.  Apple wants to go modualr
with its operating system and this in my opinion is a good thing in terms
of the flexibility it provides.  Its shocking in terms of how much they can
justify chargin if you want all the bells and whistles, but we have to live
with that.

For an example of the things to come have a look at System 7 file sharing.
Haven't you marveled at the way the Users & Groups control panel looks just
like the finder and you can drag things from the control panel to the
trashcan?  This is achieved using what is going to be known as the drag
manager when they finally get around to letting the Developers at it.
There was a video shown here that was from the Apple Developers Conference
which showed OCE (Apples application level mail interface) in action.
Applications can bring up the standard mail dialog (They had working
versions of Quickmail, A Compression Program (Can't remember which) and
WordPerfect all with same interface) use a server to find the address of
the person they want to mail and then attach documents.  To attach a
document, you go to the finder and just drag it into your attach documents
window of your appplication.

File sharing is just one example of the wonders to come.  It probably
shouldn't have been included in 7.0, but was really needed to make aliases
work effectively.  You can simply make all your documents available to the
world.  Given that aliases are an essesntial part of Quicktime and Publish
and Subcribe is much more useful with them.  All of the amazing features
become somewhat less amazing when file sharing goes.  Who hasn't got
aliases for all the commonly used servers on their desktop?

System 7.1 in itself is pretty wishy washy.  But it will provide you access
to OCE which makes it an essential upgrade to anyone who is going to want
to send mail on their mac as all of the mail interfaces that you know and
love will probably move to OCE as soon as it is practical.  Who doesn't
support Quicktime and uses a proprietry format?

More meaningless drivel from the person who didn't bring you baked beans.

Anyone any ideas on this? Could this be local finder memory? T'aint
system memory - got lots of that - unless the finder cannot get at it for

Maybe "Lots" of people will, but will it sell enough copies to make it
pay?  Remember, Egghead got badly burned, and both they and Microsoft
got some bad press with the Windows 3.0->3.1 upgrade.  Seems customers
weren't breaking down the doors to buy it like they thought they would.

Au contraire.  A vast number of Mac users are still using System 6.0.x  A
vast number of Mac users have *never* upgraded their system software and
wouldn't know how.  I'll admit that most of the Mac hard core users will
do so (how many of *you* installed System 7 the first week it came out?)
eventually, but there may be enough reticence to do so (in conjunction
with the sense of no clear value added) to cause problems for Apple
in a public relations point of view and I don't think it's worth it to
Apple for system software releases to be perceived as not a "good buy."

Does anyone know if there is going to be a new upgrade for Autodoubler which
fixes the problem that it had with AppleShare?
If so, could you E-mail me any information?

I posted an article about MacTCP costing $100 for an UPGRADE and I am
still seething. The is the "Read my lips - no new taxes" syndrome. Get
people hooked and then start charging.

I MUST upgrade as I do product development on my office system. I have my
own personal PowerBook and keep it in synch with my office machine. The
two system levels need to be kept close together, if I am to do any work
on my home machine, then it must be at the same, or close, level to my
office system. In short, I will have to upgrade eventually.

Boy - I am hopping... I wonder if that job in the bicycle store is as
frustrating as this one.....
