I think the relevant "timing cycle" is the time when the 6510 gets off the bus and the VIC-II gets on the bus. If that is 20ns (and I think it is less), then I think that defines the timing. 20ns is 50MHz... It's probably a bit longer than that, but coupled with the above, I think problems could develop at far lower speeds. Actually I haven’t thought of AEC related stuff, which can be more timing critical in fact. Hm, still - grabbing some scope pictures could lead us to a viable upgrade/fix for the SX. -- SD!
