TI-80
From Free net encyclopedia
TI-80 is a graphing calculator made by Texas Instruments. It was originally designed in 1995 to be used at a middle school level (grades 6-9).
The TI-80 featured the smallest screen and slowest processor (980 kHz proprietary) of any TI graphing calculator. In comparison, the TI-81 featured a 2 MHz Zilog Z80 processor. However, the TI-80 did feature 7 KB of RAM (compared with the TI-81's mere 2 KB). The TI-80 also had more built in functions than the TI-81 (such as list and table functions, as well as fraction and decimal conversions). Like the TI-81, the TI-80 did not feature a link port. The TI-80 was also the only graphing calculator to use 2 CR2032 lithium batteries (instead of the standard 4 AAA batteries with a lithium backup battery).
Since its release, it has been superseded by the superior TI-73 and TI-73 Explorer and has been discontinued.
