Your right Neil, thats exatly what it said and I'm sorry, I must have
somehow overlooked those very words. It's good to see Amiga Active
informing us of unclear ground.

Its a shame you were unable to provide us with some figures.

Thanks for the advise Neil and the others that have advised, thats dispelled
some myths and rumours about the CPU being the bottleneck more than the
interface. I believe santa will be getting my christmas list very soon
with a silver surfer at the top, underlined and in bold (I wonder if his
e-mail package can read that).
