No, I was thinking about your CTRL-ALT-DEL and lingering keypress problem, but now I think about it that was the 536, so nevermind (I was wondering if something were triggering earlier because of the faster E clock).exxos wrote: ↑Tue Apr 19, 2022 12:45 pm I've lost track whats what. The SEC booster was only resetting AFAIK when running 64MHz due to bus loading. It would run fine on 50MHz. The ACIA's are rated up to 2Mhz anyway, so they are not being " overclocked" as such. But obviously they are not being clocked at 500KHz either.
