Welcome to my site. I create this pages to share information regarding old calculators, computers and other vintage electronics. I've collected a lot of small hand held calculator from the '70s to recent times and some technical information about the products. You will find useful technical information about the silicon, batteries, power voltages, connections, and other. You could use it in order to restore (at your risk) your vintage calculators and have the opportunity to switch it on again. (PT)
