Quadra 700 Speed Performance Charts

The following Excel 4.0 document shows the performance curves generated
from 25 to 36 MHz based on benchmarks run on a Quadra 700 with the
Variable Speed Overdrive, and having placed pin sockets for the 50 MHz
crystal. This is sort of a follow up to Guy Kuo's reports on replacing
the crystal for a higher frequency one. I hope you find it useful if
you're trying to select an appropriate speed or, if you just wonder what
kind of beast lies inside that box. All of this came up after exchanging
some e-mail with Guy and finding on both of our machines a zone of
no-tolerance (with VSO around 33 MHz).
In my particular case I found an optimum range of speeds with no
performance degradation.

Due to the number of private requests I keep getting for info on the quadra
videos, I can't get any of my own work done!
I am forwarding the following document to the archives. It describes the
quadra internal video very well and should be very useful to many quadra
owners. It is written by the designer of the quadra video himself, Dale Adams,
and was originally posted in comp.sys.mac.hardware (I think).

A review of the Macintosh Quadra 630
In August of 1994 Apple Computer Inc. released a new line of their
popular Macintosh computer. The models introduced are the Quadra 630,
LC630, Performa 630, Performa 630CD, Performa 635, Performa 636, and
the Performa 636CD. All the models are similar, such as case design,
hard drive capacity, and ports, but there are some differences. The
Quadra 630 is the only model to have a full MC68040 with the floating
Point Unit(FPU) for math intensive tasks and is geared towards
businesses. The LC is for the educational market and the Performa
models are for the consumer channels and come in many different
configurations. This review will focus on the Quadra 630, but should
also apply in part to the LC and Performa models.
What you get for $1189 (street)
1 Quadra 630 with 4megs Ram, 250meg IDE Hard Drive, 1.44mb floppy
I recently purchased the Apple TV/Video System for the Quadra 630
and thought I'd share my experiences with it, this should also apply
to the Preforma and LC models. Before buying the Quadra 630 and the
video system, I owned a Quadra 660av and will make some comparisons
between the two.
WHAT YOU GET for $249.
A Manual (clear and well written).
1 Disk with the Apple Video Player extension & application.
1 CD-ROM with Avid VideoShop 2.0 and upgrade coupon to 3.0
1 Screw.
1 Remote control w/ battery (cool!).
1 Cable/Antenna Tuner Card.
1 AV Card w/S-Video IN, Composite Video IN,Stereo Sound IN
1 Warranty Card.

For those of you who expressed interest in the Radius Rocket upgrade path for
the Mac II line, I use a Radius Rocket Nubus accelerator with a pre-release of
the software v1.3 they call the RadiusWare. Here is what I can share on that
subject/product.

If you are thinking about upgrading your Mac II, IIx or IIcx, you have several
options, not just the Rocket, depending on your priorities:
a) you can go quadra 700 only if you possess a IIcx, that will give you speeds
greater than those offered by the Rocket, but not so much greater that it
should be your only concern (in fact those concerned with speed should either
go the Next route, or for those spending somebody elseUs money, the Silicon
This text describes how to refill your Deskwriter or DeskJet ink cartridges.
It is a summary of experiences by different people. This text has been
posted to the mac archives before, but it was deleted. I repost this
article on multiple request.
1) Why to refill your cartridges ?
----------------------------------
Deskwriter cartridges are pretty expensive. But there is a quick and easy
way to refill your cartridges yourself
2) Why not to refill your cartridges ?

I haven't decided on a final solution yet, although I did find out
that a company called "Pre-Owned Electronics" (check your favorite Mac
magazine's small ad/classified section for details) offers a
refurbished, 90-day-warranted replacement FDHD for $169, and they'll
give you $40 for a trade-in of a damaged drive. That's a net cost of
$129, which is the best net cost I've seen yet.
