My Replica 1 Page

Most of people interested in the Replica 1 device do not live in France... Thus sorry, these pages are in English...

Welcome to the Replica 1 web page. 

This site is about my Apple 1 computer replica, the Replica 1 sold by Briel Computers. This site contains all my works and experiments on this incredible board which enables to take us back to the good old days of the first 8-bit microcomputers.



This is me with my Replica 1, just right from the very first power on, after 3 hours of intensive soldering and checkings. I hooked the board to my old Apple 2 monitor, took a deep breath and turned the power on. Great, this works! Behind me is the famous french computer newspaper "Hebdogiciel", issue #90, 1985, July 5th whose headline was "Les flics d'Apple (Apple cops)".
