I were mainly thinking on the local bus that is physically wired to Agnus (OCS/ECS/AGA), Paula and Denise etc.

So clocking the CPU socket (bus) faster than 28 MHz is pointless except for any onboard memory (60 ns dram?).

Looking at the A1200 motherboard I think the datasheet for the "CSG 8374" would probably answer my questions ;)
