Quick follow up to last message.

My thanks to Quinn, whose real name I forgot, for the PowerBook key swap
info.  The escape key was driving me crazy.  What exactly is the 'slosh'
key, though?

Secondly, for those who asked, I am using a Global Village Bronze for my
PB 100, and it works great.  From what I have heard, the normal Apple
internal modems have shown some flakiness for other users. Any other
opinions?

Well, it depends how you define "SE/30"!  I upgraded my SE to an SE/30 and the upgrade
included not only a mother board swap but a new chasis, front panel and even a new label
for the back which make this indistinguisahable from a factory-built SE/30.  I did not,
however upgrade the drive to a super drive since they wanted another $300 for this.
So beware, it might look like an SE/30 and even quack like an SE/30 (in stereo) but
it might still have an 800K floppy.

Recently I have seen a lot of adds for scsi-2 based disks. Is it possible
to use these disks with a normal mac, say a IIci, and hope that eventually
my mac will have a faster scsi (via upgrade, or new purchase), but the disk
will still be around?

I'm looking for information on CD-ROM drives which come with magazines
that hold multiple disks. I've heard of the Pioneer drive which holds
6 at a time and would like information about other choices and information
about the quality of any options. 

I will have a set of 13 disks, probably growing to 14 by the end of the
year, to search. The last two years of info are contained on 4 disks
and I expect them to be used much more than the others. 

If this topic has come up before, I'd appreciate a summary. I will post
a summary as soon as I can.

You might want to clean the mouse.  If there's some dirt or a hair
in there, it can do what you are describing.  

I often pop open my mouse and blow some air into the thing to dislodge
any foreign matter that has worked its way in.  Some mice have a tendency
to collect dirt in them.

Basically, imagine that you have a program, with instructions A B C D
and E.  E happens to be a "loop back to A" instruction of some sort.  B
is an "increment the following location" instruction.

So the machine runs A B D D E A B E A B F D E and so on.  All is happy
(except that the programmer wasn't following Apple's rules).  Then we
get a chip with an onboard cache, which allows tight loops to run
completely inside the chip.  Now, when B modifies the next location, it
modifies the location in the DATA cache, not the INSTRUCTION cache... so
you get A B C D E A B C D E etc.

An external cache (like a IIci cache card) isn't split instruction &
data like the '040 cache, and doesn't hit the problem.  That doesn't
mean self-modifying code is smart :)

This should be on your Tidbits disk; it's called Cache Control, and has

Nope.  That's a different potential incompatibility altogether. :-)

We'd like to be able to hook up our Powerbook 170s to another monitor

the Powerbook; just the ADB, modem, printer, mike, speaker and SCSI ports.
Is there any way to interface to projector panel to the Powerbook thru,
say, the SCSI port?  Any special adapters, software, etc. like that?
Or are we just gonna have to gather people around the Powerbook? 8->

I have a Mac LC with an internal HD, an external HD, and a GCC

safe to leave off one of the two external devices in the

There are occasions when I want the printer, but not the external HD.

Any thoughts?

This is simply not true. The 68040/33 beats the pants off any 486

Domain/OS and Solaris do.  It's certainly not common though.  There

The clipping noises are possibly artifacts from the Sound Manager being
affected by the Power Manager.  Wait for System 7.1 (hopefully) and the
new Zap, Pow Wizz Sound Mmanager that Apple's working on presently.  It
might fix the problem.  

The FaxModem in my 170 appears to put hard disk noise out through the
