I finally ran Dread on my A500 as it is intended. I was running the A500 stock except for the CPU which is an 68010. Would that make any difference? I guess with unrolled loops it doesn't. Anyways,...

Let me think aloud here. First thing to change is to make AS7 a tristate signal when another busmaster is active. Easy in a CPLD but on this design it would mean an extra (tristate) buffer gate. Or...

I have raised an issue on GitHub. One thing I just now realize is that this design does not tristate the AS signal when the 68000 grants bus access. This inhibits any DMA transactions on the 68000...

Also, the accelerar always runs @14Mhz. However, when it accesses the Amiga bus the cpu is slowed down so much tools that like Sysinfo will report a slower clock speed.
