The TI-38 was a simpler version of the TI-35 introduced in the same year. Instead of the statistical functions of the TI-35 two conversion functions were added: DD<->DMS (Decimal Degrees to Decimal/Minutes/Seconds) and P<->R (Polar to Rectangular coordinates). The goal was to replace the TI-30 but market acceptance kept low.
Simply by comparing the designation of the integrated circuits of the calculators you'll get the first members of the slimline family:
|• TP0320 (CD3201)
• TP0320 (CD3202) TI-30-II
• TP0321 TI-50
• TP0322 TI-Business Analyst-II
• TP0323 TI-53
• TP0324 TI-35
• TP0326 TI-38 and TI-20
Don't miss the TI-20 based on this TI-38.
In 1984 the era of the slimline calculators was over and Texas Instruments introduced a family of three calculators manufactured in Taiwan:
• TI-35 II
• BA II
Don't miss the rare Business Card, probably the missing calculator using one of the TP032x chips.
