TIP for 68k and PowerPC Macintosh
=================================
This is the repository for a Macintosh port of [Gibson Research Corp]'s
[Trouble in Paradise], a diagnostic and repair tool for Iomega Zip and
Jaz Drives. A big thanks goes to Steve Gibson for the x86 source that
made this project possible!

Compatibility
-------------
This tool is meant for Macintosh computers with a SCSI port, which
range from the Macintosh Plus, released in 1986; through the "Beige"
Power Macintosh G3, released in 1997.

It has been tested in on the following environments:
| Computer | Memory | System | Drive | Firmware |
|------------------- |--------|--------|-------------------------------------|----------|
| Macintosh Plus | 4MB | 7.0.1 | Zip Plus 100 Ext. SCSI | J.66 |
| PowerBook 3400c | 144MB | 8.6 | Zip 100 Ext. SCSI | E.08 |
| PowerBook 3400c | 144MB | 8.6 | Jaz 2GB Ext. SCSI w/ 1GB media | E.17 |
| PowerBook 3400c | 144MB | 8.6 | Jaz 2GB Ext. SCSI w/ 2GB media | E.17 |
| Power Macintosh G3 | 256MB | 9.2.1 | Zip 100 Ext. SCSI | C.22 |
| Power Macintosh G3 | 256MB | 9.2.1 | Zip 100 Int. SCSI | J.03 |
What will not work or is missing:
* USB connected Zip drives have been reported to not work.
* The functionality for operating with password or write protected disks has not been ported.
* The partition recovery feature has been removed, since it is meant for PC disks.

Unmounting volumes
------------------
**To avoid data corruption, a cartridge must be unmounted prior to
starting a test with TIP!**
The best way to accomplish this is to start TIP without a disk in the drive you want to test.
Then, insert the cartridge at the testing screen which indicates "Awaiting media...". TIP
will recognize it if Mac OS mounts newly inserted cartridge and will give you the choice to
unmount it.
Alternatively, you can use the command line from the "Advanced" menu to unmount a disk
**prior to** starting a test.
Click here to learn how to use the command line
The command line is accessible by selecting run "Run Command Line..." from the "Advanced"
menu. This is a unique feature of this port and is not present in the original TIP:
![Command Line][mac-screenshot2]
### Unmounting Volumes
A cartridge will show up in the Finder as an icon; MacOS calls this a "volume".
To prevent data corruption, you have to "unmount" the volume prior to testing.
When a volume is unmounted, the icon will disappear from the Finder, but the
cartridge will remain in the drive. To unmount a drive:
* Type `volumes` to show a numbered list of all Mac volumes
* Type `unmount` followed by a volume's number to unmount it.
*The unmount process will fail if you have any open files or applications in
the volume; if this happens, close those files and try again.*
### Listing SCSI devices
* Type `list` to show a numbered list of all SCSI devices by SCSI ID.
About the code
--------------
Portions of the original code have been re-written in C++ and adapted
for compilation using [Metrowerks CodeWarrior 8 Gold]. The code is located
in the `mac-cpp-source` directory.
Click here to learn more about the code
![Metrowerks CodeWarrior 8 Gold Project][mac-screenshot3]
Native [Macintosh SCSI Manager] routines have been substituted for
the Win32 ASPI routines and the UI has been re-created as closely as
possible using QuickDraw routines.
Although the source code is materially different, I have maintained the
layout and routines names of the original assembly code to allow for easy
cross referencing and to make it easy to port additional functionality
in the future.
