INTRODUCTION
The TI-80 was released with Algebra I and middle school students in mind. Like
the TI-81, it has no link port and is not intended for serious programming.
The TI-80's newer cousin, the TI-73, sports flash upgradability and more
memory, and has completely replaced the TI-80 in everyday use.
