I have been using my TI-66 since purchased, I believe in 1984 on a regular basis and has yet to fail me.

TI-66 has 14 segments (Alphanumeric-display) Just like the Hp-41 and other starburst display calculators! It was first used in early 1980, with 47 with on/off keys!

It also talks just like speak & spell!
