Instruments introduced with the TI-58 and
TI-59 in May 1977 a novelty, the Solid State Software Modules™ with up to 5000 program steps. On
the backside of the TI-58/59 you'll notice a small lid with a place for a module.
The Master Library with 25 different programs was included, a lot of other
modules were available.
American Micro Products of Richardson, Texas addressed with this unique CROM Selector three known problems:
|• The access to the
module compartment isn't possible with
the TI-58 or TI-59 attached to the printing cradle PC-100A.
• The calculator has to be switched off to change the module.
• The contacts inside the calculators are sensitive to mechanical
and electrical destruction.
The Module Selector fits neatly into the charging bay of the PC-100A and holds up to four Solid State Software Modules in place. Selection of the module is simple and straightforward with a 4-position rotary switch.
The Module Selector should be compatible with the PC-100B and PC-100C printer cradles, too.
American Micro Products sold in 1979 not only the featured Manual CROM Selector, but even an "Automatic CROM Selector:.
