TI-1768 II continued the design line of the TI-1768 with the tiltable display
but got a smoother shape. The huge LC-display was morphed to its successor, the TI-1766+.
The internal contruction of the TI-1768 II is rather simple, the printed circuit board (PCB) looks like most other designs of that time frame. A flexible connection between the LC-display and PCB is the whole trick. This TI-1768 II manufactured in November 1991 by Compal Electronics in Thailand sports a Sharp LI3135 calculator circuit. A later model, manufactured in 1995, was based on a LI3154 chip.
Don't miss its sibbling TI-608 and the related ibico 076S calculator.
The TI-1768 II is featured in the Texas Instruments Incorporated sales catalog CL-1233 dated 1994.
