Sorry, to get your hopes up. I just ammended my last post there. I was running through a clock divider still. So 25 MHz it is right now.

Will still be pursuing how fast I can push this. You still hold the crown as fastest, by a long margin.

Hopefully, if nothing else. You now know that the figures I report are in complete honesty.

Oh, OK. I’m excited that more people are looking into overclocking 6502 with different set of hardware. I think using 65C22 as the I/O device has great overclocking potential.

Will certainly keep you posted. It got to 25 MHz effortlessly. So I am hoping I can squeeze a lot more out of it.
