As promised, the ZipTalk init 1.0 written by yours truly for Zip technology.

They should be incorporating some of this into their standard issue software
soon, but until then here's what ZipTalk will do for YOU:

	AppleTalk Delay is no longer needed (unless you like a slower system)
	Accelerator may run at ANY speed and appletalk will still work
	The GS/OS accelerator control vector is patched to work with the Zip GS
	The disappearing cursor problem is fixed (just a toolbox patch, really)

AppleTalk is NOT required, the init will still install the accelerator vector
patch and the cursor patch. If AppleTalk is installed, however, there is one
thing you need to do:
	SLOT 6 OR 7 MUST BE "NORMAL" TO THE ZIP. This is automatically taken
care of if slot 6 is set to Disk Port. If you have a ROM 1, slot 7 must be
set to built-in AppleTalk anyway so I recommend setting the dip switch for slot
7 to normal (that's what I do and it works fine).
	IF anything is wrong, you will get a dialog telling you to set slot 6
to "Normal". Otherwise, don't worry about it.

	Once the init picks a slot (it tries 6 first, then 7), it relies on
that slot being set to normal for the AppleTalk packet receive fix to work.
I have to do it this way because of the way the AppleTalk IRQ manager works.
This init had to be 100% Apple guideline compliant, so I couldn't do anything
deep to the AppleTalk manager.
