Josef's MUSEUM OF
TEXAS INSTRUMENTS CALCULATORS

Welcome to my pages.

My history : When I was small boy I dreamed about a computers. After high school I get my first job - technician in a computer firm and I have filled my destiny :)

These are my first mechanical (1920) and electronical computers (1989).
