Inspecting the PCB of this TI-1795 calculator brought our attention to a small mark reading SD9-15, most likely a reference to Type Small Desktop 9 and Revision 1.5 of the design (schematics and layout). We spotted this PCB-Mark already with the near identical offspring Radio Shack EC-2006A and started compiling a list of the PCB-Marks on calculators manufactured by OEMs for Texas Instruments.
In 1991 the size of the solar cells was reduced and production of the TI-1795 was shifted to Thailand.
