Does anyone know how an external accelerator synchronizes with the internals of an Amiga 500?

The accelerator goes 28mhz and the A500 goes 7 mhz.
Thanks in advance.


Well, only one CPU can exist at a time, EITHER the External accelerator, or the Internal CPU.

If the External accelerator is present at boot time, then the 68000 will be sent into a sleep (HALT) state.  There is no physical way around this on the A500 (Any Amiga as far as i am aware)

Even the Phase 5 accelerator with 040/PPC on them, only one CPU will physically exist at any given time (AFAIK).
