When Texas Instruments launched in May 1977 the TI-58 and TI-59 programmable calculators, they opened the way for dozens of application specific solutions using the new Solid State Software Modules™ with up to 5000 program steps. 

Reynolds and Reynolds, headquarted in Dayton, Ohio, introduced already in October 1977 with the COMPEG 2001 payroll computing system the first application programmed in a customized Solid State Software Module™.

We know five different approaches of the module expansion:

bulletStandard modules like the Master Library use only the small sticker above
the A,B,C,D, and E keys.
bulletOther modules like this COMPEG 2001 payroll computing system developed 
by Reynolds and Reynolds make use of a colorful keyboard mask.
bulletCustomized calculators like the USMC AV-8C calculator or insurance calculators
sold by Allianz and others use special keyboard arrangements.
bulletThe CAL-Q-TAX calculator uses an extender instead the usual drop-in modules.
bulletThe Kodak Q-700 Program Adapter makes use of a snap-on cover with an
individualized printing.  

Dismantling the COMPEG 2001 calculator reveals a standard TI-59 calculator manufactured in December 1977.

The Reynolds and Reynolds Company:

Reynolds and Reynolds was founded in 1866 as a business forms printing company by Lucius D. Reynolds in Dayton, Ohio. In the 1920s Reynolds created the first standardized accounting forms and a paper-based accounting system for Chevrolet and its retailers. The innovation also laid the groundwork for Reynolds to become the major forms and systems provider to the automobile retailer market. In the 1960s Reynolds became the first to offer computer services to automotive retailers throughout the nation – a key step in transforming the way individual retailers and car companies managed their businesses. 

In October 1977, Reynolds and Reynolds introduced with the COMPEG 2001 payroll computing system the first application on the then brand-new Texas Instruments TI-59 utilizing the Solid State Software Modules™.

On October 26, 2006 Reynolds and Reynolds and Universal Computer Systems, Inc. have completed their merger. The new company will be known as The Reynolds and Reynolds Company and serves more than 15,000 dealerships worldwide.
