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) TI Investment Analyst |
| 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-30 III |
| TI-35 II |
| BA II |
Don't miss the rare Business Card, probably the missing calculator using one of the TP032x chips.
