not sure if it's beneficial having a number of buffers and

 This came up in one of the threads about the topic of either simulating
 Massbus or HP 790x disk, I think.
 The problem was the controller timed out if the head-head
 switching time wasn't fast enough. 
 
We're back on talking about interfacing to a drive though, not emulating that
drive, so I don't *think* there should be any theoretical issue with reading
or writing head-at-a-time or multiple heads in parallel. In practical terms
though, anything which can speed up data acquisition is probably a good thing.
