At 8-bits for this sort of thing the IIci built-in video will be similar to
a non-accelerated NuBus card (yes, many other things may be slower, but not
scrolling).  You're better off getting a cache card to improve this one, or
looking into accelerated NuBus cards.  Going to a Quadra you'll see a big
difference!  The built-in video on that machine beats accelerated NuBus
cards.

Also, for scrolling performance you can help a lot by dropping to 1-bit
mode.  There are INITs around that let you do this quickly, so you could
drop to 1-bit while navigating around your Word document, and be in 8-bit
lickity-split for Solarian :-)

I think you're gettin the two mixed up.  Everything is opposite of what you
say. the 1304 is the better monitor that is multisync and multiscan.  As far
as i'm concerned the 1320 is a waste of money

This sounds good, but will they be cheap enough to compete with the
486 clones? Will I get a 610 for what a IIvx costs today?

This one might be really good as a home Mac, as long as it isn't crippled
some other way. I can stand 16 MHz bus in this case - though it was a
horible crippling of the IIvx. (The LC III should, even with a slower bus,
still be much faster than the LC/LCII and most of the time faster than IIsi.)

>+ Color Classic: a 16MHz Classic II with color.

I thought this would be 25 MHz 32-bit, sharing the architecture with the
LC III? The 16 MHz 16-bitters must go, they are too far behind today.
The color Classic can become a nice low-end color Mac, but only if it has
decent performance and is dirt cheap at the same time.

They have to. The 486's are just Messdos-PC's, but they have dropped so
incredibly far down the last year so it's getting hard to motivate
a Mac (despite the price cuts and slightly improved price/performance
of IIvx and P600). Apple must follow *now*, and a lot more than they
already have. Sadly, the quality will probably suffer.

I have a Seiko 13" color monitor connected to my 6/40 LC and it's
developing a wierd quirk.  About once or twice per computing session
(avg session time = 3hours) the display on the screen will "bounce."
It's not easy to describe this bounce.  The whole desktop rises about a
quarter of an inch and then drops down about a half inch and then rises
back up to where it was originally.  This happens VERY fast.  It's
sorta what one might expect if power to the moniter were suddenly lost
and then very quickly regained.

Anyone else seen this?  Any ideas what's going on and how I can
stop it?

Thanks in advance!

Better ask your store if he's in Apple's "educational channel" -> read

This sounds exactly like the problem I reported here a couple of days
ago with my SE/30 8-80; in particular, the bombs under AD. 
I got one answer from a friendly guy quoting the relevant pages from
"The Dead Mac Scrolls" (after the bombs and freezes, I had had sad Mac
codes during booting, and my Mac is dead for the time being).
Unfortunately, the Dead Mac Scrolls did not help in this case; in fact,
I had looked at the book myself today and found out that with my hard
disk I should not experience this problem at all...
I still suspect that it probably has something to do with the SIMMs,
both in my case and in yours. If during installation you touch the SIMMs
and a bit of fat gets on them they may corrode partly (tiny parts on
them) (this is how I understand it; I'm not very technically minded).
This typically causes unpredictable errors like those we are
experiencing.
I believe I read something about "cleaning" SIMMs - does anyone know how
to do this?
Hopefully, the information interchange will go on!

I have a sometimes living, sometimes dead Mac SE FDHD that seems

powered off, and fire it back up, the hard drive kicks in, but the

We have several 1 GB Magneto-optical drives from Macinstor. Our experience
is that these drives is very  slow: (aver. read: 33 msek, aver. write: 130 msek).
We would never
use these drives as the primary harddisk on a computer. We use them for
storing big images (for our reseach).
Another problem on these drives is that they crash rather often. Maybe that
this is not a problem on other magneto-optical mecanisms. We have heard about
a 650 MB M-O drive, which is more robust.

My P-chem text says that diffusion is a function of temperature in degrees

If so, then I believe the ad is in error. Everything I've seen in Daystar's
Compuserve forum indicates the offer was only good until November 1.
I also saw a post from someone who saw an incorrect ad which claimed
the offer was good until November "31" and bought a 50 MHz 030 accelerator
on November 3, and thus far Daystar is refusing to give him any special
consideration on the upgrade deal.

Clarification:  Some folks don't understand why I am referring to this
situation as less voltage.  The power supply voltage is fixed.  More voltage
drop on the PC board trace between the supply and the CPU chip means there is
less voltage across the CPU chip.  If the CPU has less voltage across
it, it will draw less current.

V(CPU) = V(supply) - V(PC board trace voltage drop)

I know this is probably obvious to most readers but some mail I got seemed to
imply that the CPU voltage would remain fixed and the power supply output
voltage would increase as the PC board trace resistance increased.  This is
not how the system is configured.  The power supply voltage is fixed.
