This Macintosh application allows you to view and print a map to the CalTech
introduction of the Macintosh PowerPC.




Text File for Tech folder which describes how to accelerate a Centris
610 to Centris 650 speeds and beyond by changing the clock oscillator.
This procedure is similar to that for the Quadra 700.

This information is only for those who are technically adept. The process
requires soldering leads to surface mount components. This is not a good first
soldering project and should be done only with electrostatic discharge safe
equipment and the usual ESD workmats, etc. You will void your warranty. If you
ruin your motherboard, your friends will laugh at you.

Now that you have been properly warned, the procedure:




Dear All,

A week ago I sent out a request for information about the built-in ethernet
connection in a Centris 650 (as in our College Microstore didn't want me to
use it). I enclose the responses I received for filing as a report.

The consensus is that the inbuilt connector is the thing to use, with the
caveat that Apple's self-terminating transponders may cause problems. One
respondent seems to have had very bad problems with Quadra 700s, cause
unknown.

Many thanks to all those who replied.

Here is a very informative report on the built-in video capabilities of the
Apple's new Centris 610/650 and Quadra 800 machines. The report was
written by Dale Adams, the designer of the video hardware on those
machines. It includes a complete description of the available resolutions
and bit depths, the types of monitors supported, and the video connector
pinouts (including the sense pin configurations necessary to enable the
various display types).
