Won't work on the Amiga without disabling the multi-tasking.  To do
this kind of control requires taking over the machine so you can
always toggle the signal at the right time, something which the
multi-tasker pretty much guarantees won't happen while it's running.
A dumb idea anyhow, as the timing is extremely device specific - the
timing that will work on an NEC drive probably won't on a Fujitsu, and
vice versa.

While I agree with the philosophy of "attempting to elicit discussion
by provoking thought and response", I have to draw the line when the
topics being discussed are, basically, a waste of time.  It has long
since been determined that the Amiga drives cannot read Mac disks.
Period.  Further discussion is less than useless, and will, in fact,
just confuse those who aren't as familiar with the Amiga capabilities
as some of us are.  It is important to keep in mind that the purpose
of this forum is to provide useful information and intelligent
commentary on the Amiga, its capabilities and its possibilities.  By
engaging in "discussion" which is misleading or downright wrong, you
are filling the bandwidth with fog.  I, for one, don't appreciate it.
