Zorro III has a theoretical limit of about 50 MB/s using full cycles, or 150 MB/s using multiple transfer cycles within full cycles (eg, "burst). The A3000's Zorro III implementation has a practical limit of about 20 MB/s without burst. You would really need a microprocessor that "spoke" Zorro III as its native bus interface to get close to the theoretical limits for the bus master half of the transaction, though its not all that difficult to make a memory slave device that closely matches the ideal Zorro III cycle. -- Dave Haynie Commodore-Amiga (Amiga 3000) "The Crew That Never Rests" {uunet|pyramid|rutgers}!cbmvax!daveh PLINK: hazy BIX: hazy "What works for me might work for you" -Jimmy Buffett
