Hi to all of you hardware guru's out there. My question is this. is it possible to simply replace the 68000 running at 8 Mhz. with a 68000 at running at 16 Mhz. ?? Are they the same size ? will this cause more problems than it is worth? The reason that I ask is that a person I know locally said that it was possible and even easy. I would love to hear from every one on this subject so that I can make the best decision possible. Thanks, Joshua SLMT9@cc.usu.edu

To get the chip running faster, it must be fed a higher clock rate. BUT there's more: You cannot simply drop in a faster oscillator and blaze away...you must synchronize with the Amiga's bus...more complications. There are a number of text files out there describing modifications to run a faster 68000 in you system..you may want to take a look at these. --LaMonte "The MOST original .sig file yet: A non-existant one!"
