The SS-4002 EDITOR/ASSEMBLER Solid State Software Cartridge (SSSC) was developed by Texas Instruments for its CC-40 Compact Computer System and allows to write assembly language programs for the CC-40. The EDITOR/ASSEMBLER requires either the HX-2000 Wafertape Digital Tape Drive or the HX-5102 Disk Drive/Controller (both products and SS-4002 SSSC never released for production).

Dismantling this Solid State Software Cartridge manufactured in December 1983 by Texas Instruments in their Abilene, Texas facility, reveals a small printed circuit board (PCB) with a HN61256P ROM (Read-Only Memory) manufactured by Hitachi, Japan.

The HN61256P uses a CMOS process resulting in a very low power consumption of 7.5 mW and features a capacity of 32k Bytes with an access time of 3.5 us.
