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.

This SSSM was included with an early TI-88 DVT (Design Validation Test) 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 TP530 Memory Chips. The PCB is populated with one TP532 Read Only memory (ROM) with Custom Software CD5403.
