PowerPC accelerator - how does that work then?

oyeah! karlos provided an answer in depth i was hoping for.
i d like to mention that even i now own one, i have considered and still consider the ppc accels too complicated, too clumsy, too expensive and in the long run not dependable enough a solution as it was worth to copy. at its time they mark a point when i decided to finally turn my back on what was going to happen to amiga and i am very happy i have been not aware of the whole ppc tragedy.

@itix: it was ok as a temporary solution. The thing is the port of the OS to PowerPC took a lot longer than expected (I remember the fancy roadmaps published by Hyperion,... showing it would take a year or two

no. it was not. it scared the rest of the remaining users away. me amongst others. pretty much like x1k today only on even smaller scale.

The reason I asked this very question is that I've got plans (read "pipe dream" if you know me well enough) to make an ARM based accelerator card for A1200, using Freescale i.MX series CPU, and 68k emulator in flash ROM.

I think it's possible, considering a Blizzard 1260 goes for £500 on ebay...

sure, but forget about these clumsy multiprocessor designs. the best would be an arm cpu starting emulation from flash and then starting the system under emu. but isnt there some obstacle, like some expected memory layout in low address space not available on other than 68k cpus?
