The Zorro II bus runs at roughly 3.5 Megabytes/second.  The Zorro III bus
interface to the A3000 peaks at about 20 Megabytes/second.  So even using
some kind of programmed I/O device on the Zorro III bus, you can get around
10 Megabytes/second throughput, which is about 45 times more bandwidth than
you apparently need.  Most good I/O devices do some local buffering to keep
down the interrupt overhead.
