According to the ReadMe file, there is a modification needed to this
machine before OS 8 can be installed.
It appears that my machine still requires this upgrade.
Any ideas as to what this involves and whether or not I can do it
myself?
I live in UK.

Some of the 6200/6300 machines had an error in the ROM that causes
instability with OS 8 and up. Supposed to be a "free" fix from Apple, but
who know at this point!

There is a known hardware problem with the 6200 series (among others). I don't know if this is the problem you're having. Apple has a tester for it, and the following is from its ReadMe:


"About the 5XXX/6XXX Tester

"This document describes the 5XXX/6XXX Tester application. This application checks Power Macintosh and Performa 5200, 5300, 6200, and 6300 series computers for hardware problems that may cause the computer to freeze. The tester only works on Power Macintosh and Performa 5200, 5300, 6200, and 6300 series computers."

I can e-mail the tester to you if you'd like.

The Read Me also says:

"After the tester has checked your computer, you'll see a message. If the message indicates that a problem has been found, contact an Apple-authorized service provider or Apple customer support to have your computer repaired. The necessary repairs are covered under a repair extension program."
