special OEM version of the TI-74 Basicalc. This one was
sold to the German assurance company Hamburg-Mannheimer and usually used
together with the PC-324 battery operated printer.
The TI-74S followed the TI-58 concept with the Solid State Software Modules™ and introduced customized ROM-modules that fitted into the slot on the right side of the display.
The modules are programmable with an additional tool and could be erased with an UV light source.
Main customers of the TI-74S were assurance and insurance companies. Some applications used a lot of different modules in boxes holding four of them, each.
