The
TI-80 followed the famous TI-81 and removed some
mathematical and graphing functions. The size of the display was decreased to
48 * 64 dots what resulted in worse readability.
Another
disadvantage of the slim TI-80 is the power supply. Instead the 4 AAA-sized
standard batteries plus an additional back-up battery found in most TI graphing
calculators this one just sports two expensive CR2032 Lithium batteries.
The main features of the TI-80 in a short addition:
 | Graphing of up to 99 functions at one time. |
| Parametric graphing to analyze up to three parametric equations. |
| One- and two-variable statistical analyses with up to 99 data points. |
| Up to 37 programs with a total of 7000 bytes. |
From a technical aspect the TI-80 combines the 8-bit hardware
architecture known from the Financial Investment Analyst FIA-10
and the enhanced capabilities from the TI-95 Procalc.
The TI-80 uses a standard Z-80 compatible CPU with 8k-Byte RAM and a huge ROM of 128k Byte
capacity.
With the TI-73 the display size was
increased to 64 * 96 dots.
