Hi Willi,
I have the same doubts too, if the 32 MHz quartz will give acceleration.RS with new quartz is working very stable now. In theory it speed should be 16 MHz( in standard device is 10MHz/20MHz quartz). But as you know it is only theory. It is propably that CPU works with the same speed 10MHz, no matter how much new quartz will be set up!
So the best way to play and test it.
