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 |
|
|
|-----------------|--------|--------|--------------|
|
|
| Macintosh Plus | 4MB | 7.0.1 | Zip Plus 100 |
|
|
| PowerBook 3400c | 144MB | 8.6 | Zip 100 |
|
|
|
|
What will not work or is missing:
|
|
|
|
* Support for JAZ drives is currently missing.
|
|
* TIP will only do a read-pass and the write-tests have been disabled.
|
|
* The functionality for operating with password or write protected disks is missing.
|
|
* The partition recovery feature has been removed, since it is meant for PC disks.
|
|
* The detailed post-test explanation screens are absent. For now, I refer you to the documentation on the [Trouble in Paradise] pages.

**This software is provided on as "as is" basis and the user assumes
|
|
all risk of data loss. Although this software bears a similarity to
|
|
the original by GRC, I may have introduced errors during the conversion
|
|
process. Please do not reach out to GRC for support on this Macintosh
|
|
port.**
|
|
|
|
Where are the binaries?
|
|
-----------------------
|
|
|
|
Right now the port is in early testing, so I am not releasing any
|
|
compiled binaries. There is always a risk of data loss with a tool like
|
|
this, so please post in the discussion forum if you want to beta test.
|
|
|
|
How can you help?

Unmounting volumes using the Command Console
|
|
--------------------------------------------
|
|
|
|
**To avoid data corruption, you must "unmount" the cartridge prior to
|
|
starting a test with TIP!**
|
|
|
|
There is no way to unmount a cartridge (without also ejecting it) in the
|
|
Finder, but the program provides a Command Console that allows you to do
|
|
this and other things.
|
|
|
|
<details>
|
|
<summary>Click here to learn how to use the Command Console</summary></br>
|
|
|
|
The Command Console shows up when you first start the program. This is a
|
|
unique feature of this port and is not present in the original TIP:
|
|
|
|
![Command Line][mac-screenshot2]
|
|
|
|
Start by inserting the disk you want to test. The disk 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.*
|
|
|
|
Once you have the cartridge unmounted, you will need to tell TIP which
|
|
SCSI device to use:
|
|
|
|
* Type `list` to show a numbered list of all SCSI devices by SCSI ID.
|
|
* Type `tip` followed by a SCSI ID to run TIP on that device.
|
|
|
|
Future versions of this tool may eliminate the Command Console, if I can find
|
|
the right way to automate all these steps in MacOS :grin:

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.
|
|
|

|
|
|
|
![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.

The Original TIP For Windows
|
|
----------------------------
|
|
|
|
The source code in the `x86-asm-source` directory is the original Windows
|
|
source code as graciously provided to me by Steve Gibson. I am republishing
|
|
his code in this repository with his permission.
