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.

Well, I said that I wasn’t having any trouble after upgrading the 68LC040 to the 68040, but I’m starting to see some trouble. I’m getting a number of Type 3 errors when trying to run programs like Netscape 4 and Quicktime 4. Most programs I had been using still seem to work just fine, but the consistent failure of several programs makes me concerned that my upgrade is not entirely stable. I’ve been able to work just fine without these programs so far, but I may desire to use them at some point, so I’ve got my original 68LC040 CPU set aside just in case.

In the meantime, I am enjoying using Think Pascal. It’s pretty cool to go back to a language I only tinkered with in my youth. I’m amazed at how much you can do with Pascal on the old Mac. I’m glad I picked up that Pascal textbook the School of Computing threw out several years ago. :)
