Calculator Collection
TI Department



I am not a fan of Texas Instruments calculators. They seem like cheap toys
compared to HP's contemporary offerings - but they are an important
part of calculator history. These are some examples I have picked up over time.
If you would like to add them to your collection, any trade offer involving HP
components will likely be accepted...
