Wait a minute. I think Sheldon is being misled. Yes the Duos and PB's will 
run at 832 x 624, however if you are using an Apple moniter, you must have 
a 16" to run this mode (a 14" will only do 640 x 480). Even if you have a
multisync (like the Sony 1304), the mac will not be able to use the higher
resolution without a second cable because of the way the mac detects what
kind of moniter it is connected to. The reason Apple uses this facist 
method it that everything is supposed to be 72 dpi on apple monitors. No 
more, no less. 
     What I want to know is: can one construct a cable to connect to a multi
sync, so that all you have to do to change resolutions is flip a switch (and
maybe restart)? I have ordered a Duo dock and I'd like to be able to use 
832 x 624 without buying a 16". Of course I also ordered the Apple 14", but
I could change my order if it were possible. What's the word?

We're looking to possibly purchase a PowerBook/Color LCD projector bundle
and I'm looking for recommendations on a good color LCD display, the type
that's used on top of an overhead projector.

If you know of a good quality (clear, sharp, durable, etc.) one that will
work properly off the PB 180's video port, I'd appreciate any information
you could provide.

Thanks in advance.

I missed the start of this thread, so feel free to flame me if I miss
the point. One problem you might check is the paper. The fusing roller
(run by an ordinary heating element, *not* the low-power imaging laser)
has to get the paper/toner very hot to melt the toner. If you are using
cheap paper with high moisture content, the moisture will be driven out
and the paper will curl a lot. If you switch to "higher grade" or
copier-rated paper, it will not curl much. The LS uses the same Canon
engine as lots of other 4 PPM printers (Laserwriter NTR, HP LJIIIP,
DEClaser 1152, etc), and is a reliable engine. I have one on my desk
and have no curl problems at all.

True, but there's still the compatability issue.  You can have the best OS
in the world, but if there are only a few programs available, it's not
going to sell well.  I was considering getting a NeXT, but chose a Mac
since there were more hardware options, and the NeXT lacked some software
that I needed.

Not necessarily.  There is a point where either 1) you can't use more
registers, or 2) saving and restoring registers starts taking up too
much time, or 3) the extra bits needed to address the registers slows
down the CPU by requiring extra memory fetches for instruction data.
It's a bit of a tradeoff.  More registers is not always a good idea.
Generally 8-32 seems to be the most effective number.

I had to have the keyboard of my 160 replaced after about 2 weeks use
-- key strokes were not registering on the screen.

The keyboard was replaced under warranty and since then I've had no
further problems.

The replacement keyboard "appeared" to be in better condition than the
original that came with my machine -- the original had a few
scratches on the keys and there was a bit of paint missing on the
letter "B". I wonder if it was a reincarnated 140 or 170 keyboard?

    I would like to know about apple's expres modem for the Powerbook

that some of the error correction and compression was implimented in
software.  Does anyone have one of these puppies and can they tell me how
much performance degradation there is?
    If this modem is too slow, are there other internal modem options for
the duo?
    Finally, the MIT Computer Store has them listed, but they don't know

I believe if you install System 7.1, "About This Macintosh..." will report
that you have a PowerBook 145.  System 7.0 and 7.0.1 were released before
the PowerBook 145 existed, so they report erroneously that your 145 is a
140.

If you're running at 25 MHz, you have a 145.

The System 7.1 upgrade may include the new control panel that lets you change
the processor speed (a la PowerBook 160).

my needs perfevtly well. Sometimes I wish it had a FPU or a 68030 processor

Digital Daystar does support an extra PDS slot, but I don't think all

I lost, and had to reformat, the disk in my Duo 230 this week
and thought I'ld pass along the details for other Duo (and
normal Powerbook ?) owners.

We have some floor standing audio speakers that normally get treated
pretty much as any other furniture with a flat top surface:  i.e.,
things get put on them all the time.  I needed to use the table I
had my operating Duo on for other purposes so I moved it to the top
of one of the (also operating) speakers without fully thinking through
what I was doing.  Shortly thereafter the Duo crashed, never to
reboot until I borrowed a floppy adapter and external floppy drive.
Disk FirstAid reported that the hard disk was bad but it couldn't
fix it, so, not unexpectedly at that point, I had to reformat the
disk and reload all the software.

My guess is that the magnetic fields from the speaker were too much
for the Duo's hard disk shielding.  Be warned!

No problem, you can even mix in an 8-bit wide SIMM if available.  The ONLY
requirement is that the SIMM memory speed be fast enough for the IIsi ---
100ns or better.  The IIsi doesn't use parity, so the presence or absence
