Solid State Software and Constant Memory Expansion Modules™
The
TI-58
and TI-59 calculators introduced in 1977 a novelty, the
Solid State Software Modules™ with up to 5,000 program steps. The
TI-88 took this concept two steps further and included
two module ports providing the user with the unprecedented capability of
installing up to 30,000 steps of pre-programmed Solid State Software, or, by
installing Texas Instruments' new Constant Memory Expansion Modules, over 2,000
program steps or nearly 300 data registers could be added.
The Master Library, known as "Module -1-", featuring 12 different programs in three languages (English/French/German) was included with the TI-88. These programs cover a broad range of interests and provide an overview of the calculator's capabilities:
|
• Table of Contents (alphanumeric reference) • Diagnostic (Internal and installed memory) • Finance • Moving Averages • Root Finder (Real roots of functions) • Numeric Integration (Romberg method) • Matrices (9x9 with internal memory, 15x15 with CRAM installed) • Linear Regression (up to 9 predictors, 13 with CRAM installed) • Random Number Generator • Codebreaker (Guess 4 digit number) • Sorting (Numeric lists) • Function Evaluator (Printing plots with the PC-800 printer) |
Seven additional Solid State Software Modules™, known as "Module -2- to -8-" were announced from Texas Instruments.
