	If you are gonna use an Iomega Zip Drive on the Apple IIgs via an 
Apple High Speed SCSI card, you must remember that the HS-SCSI card does 
not supply termination power. Either you must have a SCSI device to supply 
the termination power, or 'hack' the HS-SCSI board to provide the 
termination power into the SCSI chain. The trick is to tap one of the ICs 
for a +5v power to the pin-25 of the SCSI chain (I hope I remember that 
correctly, someone wants to correct this ?).

	After that, it should all work correctly without any problems, 
under ProDOS 8 or booting up System 6.01. It technically should work under 
the Apple // series as well, but you will need to specify 32Mb ProDOS 
partitions (or for the IIGS, the first partition has to be a ProDOS one).

	Regards.
