Phase 5 weren't the only people who made Amiga accelerators though. If the Cyberstorm designs can't be sourced, what about the other manufacturers?
I guess the other question is what are people looking for here? If I wanted to run OS4.x, I'd buy a SAM440. I'd like an '060 for the A4000, but I really don't need a PPC chip. What I would like from the CSPPC however, is the UltraSCSI interface.
