The main features of the APH Scientific Calculator are: -- It has a complex number mode, as well as the usual real mode -- It is able to do numerical integrations, including complex line integrals -- It is programmable, and its programs can be written and edited with the built-in editor -- It operates in either degree or radian measure -- It is capable of reading a text file for data -- It has a printer interface with formatting (print using) abilities -- It has a "step" mode for debugging and examining the workings of a program -- All keys are redefinable -- It can plot functions on a high resolution screen, including polar and parametric equations -- A number of programs are included to perform many scientific calculations

The APH Scientific Calculator works with the Reverse Polish Notation (RPN) used by the most advanced calculators.

Contained on two sides of a 5 1/4 inch disk, APH Scientific Calculator comes with instructions on the disk, on cassette tape, and in large type. A summary of functions and commands is provided in braille. The disk and documentation are stored in a sturdy three-ring binder. Recommended ages: 15 years to adult.

Requirements to Run: This program will operate on any member of the Apple II family of computers with at least 128K of RAM. Since the APH Scientific Calculator is designed for complete speech accessibility, it requires an Echo(R) or Slotbuster(R) synthesizer.
