This is interesting. I presume in the example shown they stuck to 1MHz as it would be more reliable than clocking to the kind of speed you mentioned, again presumably because the nature of a bunch of discrete components meant the switching of logic levels imposed a hard limit?

Another sibling mentioned the Amiga prototypes, I'm again presuming that the ~7MHz that that chipset ran at was well within the acceptable ranges for clock speed using discrete components?

<grabs book and dusts-off failing pages...> On page pp 142-3 is the minimal config schematic that shows "oscillator module" (IC4) but it isn't in the BOM. However pp 108 (fig 4.2) shows it as 8MHz. IIRC it was a MAX 6 pin 4MHz module I used, later I cranked it up to 10MHz on a 8MHz 68k uP and it still worked. Crazy overclocking!
