Is Modern Memory is a scripting addition that checks whether the Modern Memory Manager of PowerMacs is in use. Also available as UCMD for Frontier users.

The app is completly freewarea and the source code is included within the package.

System Manager came into being from a desire to roll the functionality of several of my favourite apps into one app, increase the functionality of a few of them, and free up some Dock space. Other functions were, and will be, added to increase its overall usefullness such as system log monitoring, file/folder permissions control, trash management, and possible improvements to Process Monitoring to name a few.
System Manager combines some of the best features from a variety of other monitoring apps all rolled into one application.
Main features:
- CPU Usage (Dual)
- System Load levels
- Memory Usage
- Network Activity
- Process listing with kill and renice a process
- System Preference Pane launching
- Uptime display
- IP Number display
- Classic status display in MenuBar, Dock, or any graph
- Launch and Shutdown Classic

Apfloat is a C++ arbitrary precision arithmetic package. Multiplications are done using Fast Fourier Transforms for O(n log n) complexity. The transforms are done as Number Theoretic Transforms to avoid round-off problems.

Three different moduli are used for optimal memory usage. The final result is achieved using the Chinese Remainder Theorem. The algorithms are optimized for very high precision (more than 100 000 digits). The package is written to be easily portable, but also includes assembler optimization in critical parts for various processors for maximum performance.

Completly freeware for non-commercial use.
