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.

Scot Ware by Scotch Programs Inc., headquartered in Miami, Florida, introduced already in April 1978 with the CL4 cooling load calculation an early application programmed in a customized Solid State Software Module™.

We know five different approaches of the module expansion:

• Standard modules like the Master Library use only the small sticker
   above the A,B,C,D, and E keys.
• Other modules like the Pool Water Analysis developed by Olin Corporation
   make use of a colorful keyboard mask.
• Customized calculators like the USMC AV-8C calculator or insurance calculators
   sold by Allianz and others use special keyboard arrangements.
• The CAL-Q-TAX calculator uses an extender instead the usual drop-in modules.
• The Kodak Q-700 Program Adapter makes use of a snap-on cover with
   an individualized printing.

Dismantling the SCOT WARE CL 4 calculator reveals a standard TI-59 calculator manufactured in March 1978.
