The Classic II has no expansion slot, while the SE/30 does. This
can be a biggie if you think you might want to put Ethernet or an
external monitor on the thing at some time.

The Classic II has a 16-bit data path, not the full 32-bit path of the
SE/30. This means that the CPU has to expend two clock ticks rather than
one to get memory values. As a result, the Classic II runs slower than
the SE/30. Perceptibly so.                    

The SE/30 has a worldwide power supply. I'm not sure about the Classic
II, not having my glossies handy, but the Classic didn't, and they're
essentially the same machine.

The Classic II is lighter than the SE/30. While I wouldn't call the
construction of the Classic II "flimsy", the SE/30 definitely feels more
substantial.

One ADB port of the Classic II, two on the SE/30.

Let's see, what else.

Oh, yeah. Novel memory considerations on the two machines. The Classic
II will support no more than 10mb of RAM. The SE/30 will theoretically
support 128mb of RAM, but its ROMs aren't 32-bit clean, so unless you
use MODE32 (see current postings about this) or are using A/UX, you're
actually limited to 8mn of RAM. Of course, MODE32 is free, so this isn't
a big deal, really.

Oh, yes. For the difference that is least likely to mean anything to
you: The SE/30 will run A/UX. The Classic II won't.

The SE/30 was a great machine, but it cost significantly more to make
than the Classic II does. The Classic II isn't a BAD machine, but it's
no SE/30. The best comparison I've been able to come up with is that the
Classic II is the compact version of the modular LC. The SE/30 is the
compact version of a Mac IIcx. If the price were the same, and I had
some kind of warranty on the admittedly used SE/30, that's what I'd
take.

It has been confirmed by various battery experts that there is no such
memory effect.  I don't want to get into it right now but the conclusion is
that there is no memory effect, just something that looks like it.

Thank you!!  That is EXACTLY what I thought.   Before I opened my mouth

2's.  Is this true?

Whoops, looks like I was misled a bit.  After talking to some other
companies (MacZone) they told me that the "special" SIMMS are for
pricing purposes only.  I was worried that there were SIMMS that
could not be interchanged with other computers.  It seems that
that is not a problem as long as the the speed of the SIMMS are
the same (70 ns or 80 ns).

Subject: Mac IIsi, RAM and cache
Organization: Univ. of Wisconsin-Madison; Electrical & Computer Engineering
Date: 2 Sep 92 13:58:13 CDT

I use a Mac IIsi with 17MB RAM and System 7. 
That is plenty of RAM for my application (at least for now)  :)

Thus, I'm interested in effective ways to use part of that RAM to boost 
the Mac's speed, and not only my ego everytime I open the "About this Macintosh..."
box and see a huge amount of available RAM.

To begin with, I could increase the cache size to, say, 2MB.
That would definetely solve the bottle-neck created by the built-in video.
However, too big a cache may not improve the hit ratio and can 
even slow down the Mac (cache management overhead increases with
cache size).

Alternatively, I could create a RAM disk and put the whole system and 
finder there. 
The question is: Does anyone know what kind of cache the Memory 
control panel creates?
In other words, If it's a *data cache* for the HD, then it's existence is still 
necessary, even with a RAM disk.
However, if it's an *instruction cache*, then is it correct to assume that 
running the whole system from a RAM disk is equivalent to 100% hit ratio,
and therefore, I can turn the cache to the minimum size and save 2MB for other use?
 
If I buy a RAM card, what would be the best settings for the cache?
Would a RAM disk still be effective?

FOR SALE: Brainstorm accelerator for Mac Plus.

I have one "still-in-the-shrink-wrap" Brainstrom accelerator for sale.
This accelerator will work ONLY in a Mac Plus. It doubles the CPU
speed and the bus speed to achieve an overall speed increase of
approximately 225%. Your Plus must have 100ns or faster SIMMs installed.
A hard drive and 4Meg of memory are recommended for maximum performance.

I have had one installed in my Plus for a couple of months and I have
been pleased with it. It is compatible with System 7. 

I want to sell this accelerator uninstalled - you will need to remove 
a 20 pin DIP from the logic board and solder a 64 pin socket on top of
the CPU. I have installed two of these accelerators without incident ...

I would like to get $195(US). Email me (tschneid@hydra.uwo.ca) for more

I've bought a DeskWriter last year and never been upset by this choice. 

I've compared the output quality of both printers with a complex
"LaserWriter +"  test document. The DeskWriter seems to perform better.
- best gray pattern matches with screen view (better than the LaserWriter
+)
- faster than the StyleWriter
- more rugged than the Apple's toy
- Sharp thin line, (better than the LaserWriter +)

On the other side the StyleWriter is lightweight and more suitable for
transportation.
The cost of a DeskWriter is bit higher.

Finally, hp seems to be very agressive in the printer market with color
printers, upgrade availability and evolving printer driver. ( my first
driver version was 1.30 . Now I'm at version 3.1 with spooling capability
