Texas Instruments TI-30-II
This
TI-30-II is much more common than the first edition introduced already in 1981.
Please compare them here.
Using the electronics of the European TI-30
LCD and the two shell housing of the TI-35 created this
TI-30-II.
We noticed already with the TI-30 LCD a change from the original TP0320
single-chip calculator circuit to the more advanced CD4565 around 1982. Same
story happened with this TI-30-II featuring the enhanced
C-MOS calculator chips CD4565.
Two years later this model was replaced with the TI-30 III.
If you are interested in the calculating accuracy of scientific calculators don't miss the Calculator forensics.
In the same year a desktop variant of the TI-30 appeared, don't miss the rare TI-30 D.
Compare the TI-30-II with the Taiwan-built TI-21 calculator.
In 1984 the era of the slimline calculators was over and Texas Instruments introduced a family of four calculators manufactured in Taiwan:
• TI-30 III • TI-35 II • BA-II • BA-35 |
