Shortly after the TI-58 and TI-59 Programmable calculators were launched in May 1977, the first application specific solutions based on the Solid State Software Modules approach appeared on the market. Within just a few years a whole spectrum of different software modules were introduced: Payroll Computing, V/STOL Calculations, Pool Water Analysis, Screw Joint Calculations, Mud Hydraulics, Federal Income Taxes and dozens more.

The MOD TEN module developed by FFAL was used to calculate College Funding.

Dismantling this MOD TEN College Funding calculator reveals a standard TI-59 calculator manufactured in Autumn 1980 in The Netherlands.
