Over the holidays, my brother brought up my old Centris 650 which I promptly cannibalized for the sake of my P640CD (DOS) box. I thought it would be better to have a real 68040 CPU instead of the value 68LC040 chip. My only concern was the fact that I was going to be running this 25Mhz 68040 at 40Mhz. That was a bit more of a stretch from the 33Mhz 68LC040 running at 40Mhz. I’m pleased to report that the machine seems to be running quite stable with the new chip. I used some good heatsink compound. The only problem I’ve had is that Netscape 4 is crashing now. This seems to be the only app affected right now.
