i have some sample code that allows me to connect the parallel port of my
amiga to that of an ibm clone (with single cut, single jumper mod to the
ibm parallel card) so that the amiga can use the pc's hard disk.  the speed
i was getting wasn't awesome (slightly faster than a floppy through the
filesystem, or around 25K per second), but it worked (*).  the ibm parallel
port needed fix so it would play bidirectionally.  the amiga parallel port
code is in the form of a device driver, but the actual read/write to the
parallel port is easily extracted.

(*) - i had one problem with it, and the folks at CATS couldn't help me on
this one - i get access to the parallel port with the proper resource
mechanisms, and everything's fine for a few minutes, then SOMETHING reprograms
one of the bits normally assigned for centronics handshaking (which i'm using
as a bidirectional line) to be an input or output only (forget which).  if
i disable interrupts around the parallell transfer part and reprogram the
CIA then transfer and reenable interrupts, it works - but of course the
serial port, mouse, etc get unacceptably jerky.

anyways - interested?
