TI-59_SCOT_CL4_Back.jpg (303352 Byte)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. 

SSSM_SCOT_CL4_PCB.jpg (41850 Byte)SSSM_SCOT_CL4.jpg (40181 Byte)Scot Ware by Scotch Programs Inc., headquarted 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:

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.
