Dear John,

Yes, the ethernet bug was fixed... But isn't that an issue of Open
Transport - The version shipping with 8.6, and not 8.6 itself? Also, wasn't
this mainly a problem with 4 year old 7500/90 machines that only had one
crystal instead of two, specifically those with serial numbers of nn544...
and lower, along with some nn545... boards?

The issue of boosting the priority of the Finder in MacOS 8.6 does not,
AFAIK, have anything to do with removing 68k code... It's a decision that
was made in coding. **Can this be tweaked in ResEdit?**
Along those same lines, NT4's task scheduling (time quanta allocation) can
be easily tweaked with NTFrob, freely available at
<http://www.ntinternals.com>.
Cheers!
