I think it's funny how people often seem to comment about all the additional features they want to see in a product which would surely drive said product from feasible to eternal vaporware. :p
No matter, I think this is an excellent idea. The old FastLane Z3 isn't too slow - it even has a mode in which it supports 40 ns memory. Since the memory on this card is obviously much faster than old 60, 70, or 80 ns 30 pin SIMMs, I'm sure it gets accessed at the fastest speed the Amiga can go, and I'm sure it'll be faster than other Zorro III memory cards. I'll buy one.
