Last week I posed the question:  Can a 486DX/33MHz machine be *made* to run
at 40MHz or even 50MHz?

The responses varied from "No way, Don't do it!" to "Definitely."  The general 
concensus was YES, A 486DX/33MHz CAN DO 40MHz PROVIDED ADEQUATE COOLING IS
PROVIDED.  It was suggested that a heat sink be mounted on the 486 and a good 
fan be used to dissipate the heat.  I even heard from some who actually made 
upgrades to their 286 and 386 systems in this way, with success.  However, I 
heard from NOBODY who did this to their 486.  So, before I make the plunge,
who, if anybody, out there has *actually* made this modification to their 
486DX/33MHz machine, that is, who replaced the 33 MHz oscillator in their 
33MHz machine with a 40 MHz oscillator, and can still talk about it???  In 
theory, it would seem that the CPU would just run a bit hotter because of the 
faster switching times.  Mind you, the 486 does get hot enough to fry an egg 
on already!

Any, and all responses would be appreciated.

Francis
