Review: TI-66

Company: Texas Instruments
Years in Production: 1982 to 1985
Original Price: I estimate the original price to be from $70 to $100
Battery: 2 x LR44 or 2 x AR76
Type: Scientific, Keystroke Programmable
Operating System: AOS
Number of Digits: 10
Memory: 512 steps, which can be allocated to a maximum of 64 memory registers
Accessories: Carrying Case, PC-200 Printer

The TI-66 was slated to be the next generation of the TI-58C of 1978. Virtually the keyboard design and commands of the TI-58C are present in the TI-66, but there are some differences:
* The TI-66 is an landscape form with a gray keyboard, where as the TI-58C (and the related TI-58 and TI-59 has a black keyboard).
* The TI-66 lacks a card reader.
* The TI-66 also lacked a slot for modules.
* However, the TI-66 runs on coin batteries (AR76 or LR44), which can be found easily. The TI-58C family had rechargeable battery packs, which cannot be easily purchased (few vendors sell them online).
* In learn mode, when a step is registered, the TI-66 displays the key you just pressed with its mnemonic.
