23.008 Can I use Zip disks to transfer files to/from other computers?
Mac--> IIgs
Yes. However, Macs put a driver on the disk as well as a partition map.
Both look like partitions to the IIgs. Since the IIgs can't read them, it will
ask you to format or eject. Here's a trick you can try: When you insert a Mac-
formatted Zip, just click "eject" until the disk mounts. The IIgs will then
ignore the extra Mac stuff, and mount just the legitimate volume(s). (E. D.)

Shared HFS GS/Mac disks should be formatted on the IIGS because the IIGS
tends to provide a format that is acceptable to both platforms while the Mac
tends to ignore the needs of the IIGS.
Besides the standard Apple Disk Utility (ADU), you will need GenEx. GenEx
extracts the generic Mac SCSI driver from ADU's resource fork and puts it into
the IIGS' drivers folder. Thus, when ADU looks in that folder, it finds and
installs the driver and does not give the "no mac driver found" error. You can
download GenEx (GenEx.shk) and info (GenEx.shk.txt) from Ground at ...
ftp://ground.ecn.uiowa.edu/apple2/upl98/Feb98/ .
Once you get GenEx, use the following procedure to prepare Zip disks:
o- Go to the Apple Advanced Disk Utility (ADU) on the IIgs and select Partition
Drive. Delete all the partitions except one and resize that one partition to
fill up the entire drive. Click on the button to repartition the drive. At this
point, ADU will ask you if you want to low level format and warn you that it is
going to take a long time. Click on Yes.
o- ADU will wipe the drive. By doing it this way, you are giving ADU a clean
slate to install the GenericMacSCSI driver onto the drive.
o- Finally, initialize the HFS volume.
Surprise, the new Zip disk works on both the IIGS and Mac without annoying
errors!

PC--> IIgs (also, maybe, IIgs--> PC and PC <--> Mac)
DataViz sells a product called MacOpener 2000 for machines running Windows
that actually allows you to use all HFS formats, except for 400K/800K floppies,
on your PC while running Windows. This goes not only for reading the media but
also writing and formatting as well.
I put a zip disk in my Parallel Port Zip drive on my PC and formatted it
HFS and copied some of the //gs software I had downloaded. It worked on my IIgs
(equipped with a SCSI zip 250 drive) like a charm!

You can use MUG! to R/W MS-DOS formatted Zip disks. Mug! (mug101.bxy)
along with an info file is on Ground at ...
ftp://ground.ecn.uiowa.edu/apple2/apple16/System/Ndas/ .
MUG! is an NDA (New Desk Accessory) which must be started from the 'Apple
menu' (click on the Apple symbol) available at the top of a typical GS
'desktop'-type display.
One thing to be aware of is that MUG! should be used from an application
other than Finder (the usual main GS "desktop display"). The Finder and many
other applications will do a drive check, find the MS-DOS Zip disk, and respond
with something like: "Installed FSTs do not recognize disk, do you wish to
format it or eject it?".
MUG! seems to work fine when selected from Platinum Paint or PMPUnZip. (If
you start from Platinum Paint, be sure to go to 640 mode first in order to be
able to see the entire MUG! display.) PMPUnZip is, probably, your best bet
because it is a relatively small program. Once, say, PMPUnZip is started,
you can insert your PC Zip MS-DOS Zip disk and start MUG!. Setting the Copy
option to "to GS/OS", I copied several .shk, .wav, and .jpg files from the Zip
Disk to /RAM5 RAM disk with no problem.
