- I don't think so. In general you cannot speed up a computer by putting a
- faster processor in. The IIsi speedup was a exception caused by the
- triumph of marketing over engineering.
-
- Putting in 16 MHz processor won't do any harm, but it won't do any good.
- Putting in a new oscillator with the processor will almost certainly
- fail. it probably won't physically damage the computer, but it won't run,
- and that 's >probably< won't damage it.
-
- The technical explanation is that there are other chips that will only
- run a 8 Mhz. If you upgraded all the chips then it would work. However,
- some of the chips are Apple's custom chips, and will never be availible
- at a higher speed. This is why the IIsi works at a higher speed. The
- chips that need to be faster were already faster and were slowed down on
- purpose.
