-TIP: Trouble In Paradise
-========================
+TIP for 68k and PowerPC Macintosh
+=================================
 
-This repository contains the source code of [Trouble in Paradise],
-a diagnostic and repair tool for Iomega Zip and Jaz Drives.
+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.
 
-The source code in the "x86-asm-source" directory is the original source
-code as graciously provided to me by Steve Gibson. I am republishing his
-code in this repository with his permission.
+Portions of the original code have been re-written in C++ and adapted
+for compilation using [Metrowerks CodeWarrior 8 Gold]. 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.
 
-This repository will also eventually contain a port of the code intended
-to run on classic Macintosh computers.
+Although the source code is materially different, I have maintained the
+layout and routines names of the original code to allow for easy cross
+referencing with the original code and to make it easy to port additional
+functionality in the future.

+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
