TI-3000 Panaplex Calculator From 1973
Added 2025-01-23 19:44:27 +0000 UTCA classic show-and-tell plus teardown for you - this time it is a classic American Texas Instruments TI-3000 desktop calculator from 1973. Some strange surprises inside, and well worth having a close look at. Enjoy!

My Dad had a Texas Instruments computer! It was neat. Silver box, with a keyboard.
