You are correct; in fact, Disk2FDI uses PCI LPT cards and a special
cable to dump diskettes completely (GAP bytes, everything) by using the
host machine+PCI LPT to emulate a controller.

Yes, this agrees with my analysis: *if*
I/O's in ALL pc's are
throttled to that 8MHz bus rate (i.e. even on 3GHz machines!).
And, it also doesn't address how parallel ports work on *other*
machines without the ISA legacy "problem".
I did a little research on PCI parallel ports. The highest data rate
claimed on the ones I've seen is 5.5-6 MBps in EPP mode.
