Another blast from the past.

Was cleaning out my "junk" drawer and came across this calculator. I hired on with TI in 1976 in the semiconductor machine shop. In 1981 I transfered to the mold and die shop. I worked on molds for several TI products. Calculators, watches, etc.. I did the case mold for this calculator in 1988 and it went on sale at Walmart in 1989. It was only on the market for 2 years.

That is pretty cool.

It's always neat finding things of old that you had a critical roll in implementing. Fun part about machining!

Some one wants it. Neat find...

The basic 4 function hand held calculator had been around for a few years but in about 1972 a high school classmate brought in a TI SR-10 that belonged to his dad who was an engineer. It was the first "Slide Rule" calculator that featured square root and exponential functions. It cost $150 (over $1,000 in today's dollars). I remember our math teacher ranting about how the widespread use of calculators would be the ruination of kids learning math skills

Somewhere ( I think at my sisters house ) I have prototype calculator that never went on the market. Only 10 were made.

Cool story...

Cool find!

Why didn't you just use your phone?

I still have my old TI 81. Still don't know how to use some of the features.

My Dad used to work for TI in Abilene. He was facilities manager. He was the last one fired from Timex, and then the first one hired by TI that took over the old Timex building. He then shut the facility down when TI closed it down.

😬 That teacher was right. For proof just give a kid $20.67 for a $16.67 transaction. It’ll take most of ‘em a couple of day to recover from that mind eff.

Let me check my pager. I didn't know you called.

[Dale Moser]

Call? How would I call on my text message device?
