The MASTER LIBRARY-01 Solid State Software Module was developed by Texas Instruments for its TI-88 Programmable calculator system and included with the calculator.

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:

PGM 1: Table of Contents (Alphanumeric reference)
PGM 2: Diagnostic (Internal and installed memory, and display)
PGM 3: Finance (Compound interest, annuities, amortization)
PGM 4: Moving Averages
PGM 5: Root Finder (Real roots of functions, bisection method)
PGM 6: Numeric Integration (Romberg method)
PGM 7: Matrices (9x9 with internal memory, 15x15 with CRAM installed)
PGM 8: Linear Regression (Up to 9 predictors, 13 with CRAM installed)
PGM 9: Random Number Generator (Uniformly or normally distributed)
PGM 10: Codebreaker (Guess 4 digit number)
PGM 11: Sorting (Numeric lists)
PGM 12: Function Evaluator (Printing plots with the PC-800 printer)

This SSSM was included with an early TI-88 DVT (Design Validation Test 2) and sports no label.

Dismantling a Solid State Software Module included with a later TI-88 PVT (Production Validation Test) and manufactured in August 1982 by Texas Instruments in their Abilene, Texas facility, reveals a printed circuit board (PCB) to accommodate up to two TP0531/TP0532 Memory Chips. The PCB is populated with one TP0532 Read Only Memory (ROM) with with a capacity of 120,000 Bits organized as 15,000 Bytes and programmed with Custom Software CD5403 in Revision C.
