The
TI-30 STAT followed the TI-30 III. We know the
electronics from the slimline TI-35. A
similar calculator was introduced one year earlier with the TI-30. Don't
miss the rare TI-18 SLR using a similar housing.
Two years later the TI-30 STAT got a slightly different styling. Compare it here.
If you are interested in the calculating accuracy of scientific calculators don't miss the Calculator forensics.
The
CD4557A used in this calculator could be traced back to the SR-16
with the TMS1001 - the first LSI MOS
chip of the TMS1000
family. The picture at the right gives you a comparision between the modern
C-MOS design of a TI-30 STAT and the original P-MOS design used in the SR-16.
