Re: IIc+ overclocking

Hello,

I think I read somewhere about overclocking the IIc+.

Is the oscillator the only thing I have to replace or do I have to
replace the cpu and/or the memory chips also ?

Are there any (bad) side effects ?

Anyone that has done this and can tell me about it?

I haven't done it myself, but several here have.

It only involves replacing the crystal oscillator. There
are no downsides, apart from faster game action. ;-)

Unlike modern overclocking, where thermal effects are significant
and potentially damaging, overclocking a IIc+ is benign. And it
is the only Apple II model that can be easily overclocked, because
it already isolates the rest of the system from the processor clock.
