The STATISTICS Solid State Software Cartridge (SSSC) was developed by Texas Instruments for its CC-40 Compact Computer System and contains 14 easy-to-use programs chosen to serve a broad range of statistical applications:

Descriptive Statistics - Histogram
Descriptive Statistics - Means and Moments
Parametric Tests - T-Test Paired Observations
Parametric Tests - T-Test Unpaired Observations
Non-Parametric Tests - Contingency Table Analysis
Non-Parametric Tests - Mann-Whitney Rank-Sum Test
Analysis of Variance - One-Way ANOVA
Analysis of Variance - Two-Way ANOVA
Theoretical Distributions - Binominal Distribution
Theoretical Distributions - Chi-Square Distribution
Theoretical Distributions - F-Distribution
Theoretical Distributions - Normal Distribution
Theoretical Distributions - Poisson Distribution
Theoretical Distributions - Student's T-Distribution

This early prototype of the STATISTICS SSSC uses a different form factor and electrical connector than the final SS-3008 STATISTICS SSSC and fits only with the never released prototypes of the Compact Computer 40.

Dismantling this Solid State Software Cartridge manufactured in March 1984 by Texas Instruments in their Lubbock, 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.
