Yes, keystrokes. Compared to other calculators that were
introduced
around 1983 this unit is pretty slow. Also, the TI-59 which had been
introduced
6 years before the TI-66 is 2.5 times faster. |

| Comment |
A very versatile unit of quality making. Offers more program
steps
than the HP-15C. However,
compared
to the HP-15C it lacks its support for complex numbers, matrix
operations
and the solver. On the other hand the HP-15C doesn't support a printer.
Both the calculator and the printer are of excellent design! |
