An easier solution is to get whatever length cord you want and one of those
female-female modular connectors and plug the apple cord in one end and the
extension in the other end and you are in business. All you are doing is adding
a straight cable to the end so no need to check for twisted wires. there won't

Simple.  Price.  The Classic II is a cheap computer for a reason.
Computer manufacturers don't just charge arbitrary amounts of money
for computers.  Generally, the faster a computer is, the more
expensive it is to design and manufacture.

>Is this flaw repairable with a swap of components or something?

1) It isn't a flaw.  If you wanted a faster Mac you should have
   _bought_ a faster Mac.
2) No.  Going from a 16 bit bus to a 32 bit bus means adding
   components, traces, SIMM sockets, and other such hardware which
   means a) redesigning the computer, and b) rebuilding the computer.
   What you end up with is an SE/30.

We have several original Mac-pluses that we'd like to attach to
our localtalk network (other Macs on system 7) for use by
our students.

We don't have funding to buy hard drives for each Mac-plus;
with system 7's file sharing, I can see how data can be
stored on other machine's hard drives.

But, (1) can the Mac pluses use applications on the other machines
without the need for local storage, and
     (3) is it possible to start up the local Mac-pluses with
floppy drives only for system 7?


Thanks in advance for your advice.

Well, this should be clarified a bit.  Adding the extra 1/2 meg of VRAM
gives
you a 32 bit data path to video (vs a 16 bit path with the built-in 1/2
meg).
That's the way the video hardware is designed.  What this translates to is
faster drawing to the screen.  Since the Mac typically does a lot of that,
the system runs a bit faster.  Of course, if you're running an application
that isn't doing much drawing, you won't really see any change.  The
speedup
is in effect for all video modes...

There's really nothing to figure out. The Motorola processors are
supposed to be able to support several different data bus widths,
so all you have to do is set the right signals and you can then use
just a 16 bit data path.

Things can even be more complicated than just a 16 or 32 bit data
path: on the PowerBook 160 and 180, the interface to the video RAM
for the external monitor is 16 bits wide, while all other memory
accesses are 32 bits wide. The reason for this design appears to
be that a 16 bit VRAM design takes less space than a 32 bit design.
The speed of the interface doesn't seem to be badly hurt by this.
At least it's not slower than a NuBUS video card.

The developer notes on the Wayne's GWorld CD are really interesting.
It's easy to understand why some design decisions were made and how the
machines work. My only regret is that there were no notes for the Duo
machines. The Duos seem to be really interesting designs and I would
have been very curious to read about them. (Maybe the Duo notes will be
on the next CD-ROM.)

Note that PC performance is also affected by how many wait states
there are in the processor to RAM/ROM interface. The developer notes
give the wait states/access times for most of Apple's machines (not
the Quadras though... I wonder why).

You need the right cable, the Quadra senses what type of monitor it
is by the jumpers in the monitor.  Since it is not an Apple monitor,
the sense lines are not right.  You can make or buy a male /female

Something doesn't sound right. I put a Daystar 50Mhz in my IIci.
The book supplied with the card is clear on just how to do
this on a number of Macs.  Each one having their own chapter.
It is true that you need the adapter for the others except
the IIci, but no mention was made of sending it in to the
dealers.                       

By the way, there was an upgrade offer from Daystar to convert
the 68030 version to their new 68040 version which should
be available after Jan. 1, 1993. That offer only applies if
you purchased their board between August and November 1, 1992.
You may want to wait and see what their new accelerator will
cost before purchasing the 68030 version.  The dates on the  
upgrade offer came straight from a rep at Daystar. Besure and
talk to them if someone else is giving you a different story.

PBs don't need screen savers.  Even if you burn in the screen for days,

see if the portable will then boot.

Yes, they are for VRAM. VRAM gives you more colors or higher resolution.
You might be able to get 16 greys out of the monitor, or maybe 256.

If someone could post a detailed comparison of the two, I'd appreciate it.  I

Guesses on my part:

SE/30
For:
----
Seems to be a better performer than the LC II?
Has a full 32-bit external data path?
Cheaper because of built-in video?

Against:
--------
Isn't built-in video the same as a Classic, i.e. 512x342 9" monochrome?
To get 4-bit or 8-bit color video, don't you have to install a NuBus card and
drive an external 13" or 14" monitor?

LC/II
For:
----
4/80 w/ 512K VRAM configuration has more disk space, and can support 8-bit
video built-in?
If former is true, I'll get 8-bit video with an Apple 13" HiRes RGB monitor?
(Or is it 4-bit unless I get a card?)  I'm interested in color because my
wife wants to learn Adobe Illustrator et al. - i.e., do graphics stuff.
It's a brand new machine (-:

Against:
--------
Has only a 16-bit external data path?

I want this for my wife to do music (MIDI sequencing) and graphics like Adobe

Also, if you know, what's this about an LC III and some other new Macs in Feb.?
