Texas Instruments introduced in Europe with the TI-608 a small desktop calculator with a tiltable display. A similar calculator was available with the TI-1797 in the United States of America. The design of the TI-608 followed the TI-606 introduced already in 1986.

Dismantling this TI-608 manufactured in March 1987 by Compal Electronicsin Taiwan reveals no surprises. A small single-chip calculator circuit probably manufactured by Sharp and a long flexible cable to the LC-display. Please notice that the mold of the housing is prepared for a battery instead of the solar cells..

Inspecting the PCB of this TI-608 calculator brought our attention to a small mark reading SD3-12, most likely a reference to Type Small Desktop 3 and Revision 1.2 of the design (schematics and layout). We spotted a similar PCB-Mark already with the TI-1795 introduced in 1984 and started compiling a list of the PCB-Marks on calculators manufactured by OEMs for Texas Instruments.


Don't miss the later TI-608 with a much smaller housing but still a tiltable display.
