I've done this modification myself : a) software compatibility. Not too many problems. You do find the odd program that crashes. In those cases, DeciGel is a *must*. It is a (small) utility that catches references to the one big (?) problem, trying to read the condition codes directly (you should be calling the ROM), and corrects it (ever heard of self-modifying code ?). Of course, for games that autoboot, it won't help. I've heard that WordPerfect has ? had ? this problem, and I've had StarTerm crash on me, but no other problems. As for 68010 support, there isn't really anything you can do especially (except use the loop mode, which will increase speed for things like memory copying by about ... (digs up the specs ... still searching ... can't find them) 25% ?). b) This brings me to speed. I ran a few benchmarks, and found improvements varying between 0 (text, not surprising) & 10 % (various calculations). All in all, I guess it wouldn't be worth paying for (depends on the price of the 68010 really). >No need to mention the warranty, that's long expired... And I'm not >squeamish about opening the case and changing chips. There's not much to it (except taking all the screws out !). You might have to remove the drive, but maybe not. It wasn't very difficult. David Gay EPFL, Ecole Polytechnique Federale de Lausanne GAY@CLSEPF51.bitnet Switzerland Glorf ! Disclaimer: They don't even know I exist.
