Texas Instruments introduced in the United States of America in 1986 a family of three very similiar calculators:

TI-1796: Basic desktop calculator with 10 digits display capability and "Dual Power" feature
TI-1798: TI-1796 with added clock module
BA-20: TI-1798 with 6 added keys for COST, SELL, MARGIN calculations

Dismantling this TI-1796 manufactured in November 19986 by Inventec Corporation in Taiwan reveals indeed a printed circuit board (PCB) with the designation "IOTI-1796-01A" - known already from the TI-1798.

Don't miss the TI-1796+ introduced about 10 years after this first generation TI-1796.

The BA-20 Profit Manager is featured in the Texas Instruments Incorporated bulletin CL-885 dated 1986.
