I am referring of course to Dennis Ritchie, the man “…who helped to shape the digital era”, who died on the 12th of October at the age of 70, again after losing his battle with cancer (www. https://blog.polaris64.net/post/c-commodore-64-c64-emulator/ Wed, 27 Jun 2012 09:46:00 +0100 https://blog.polaris64.net/post/c-commodore-64-c64-emulator/ This is a work in progress Commodore 64 emulator written from the ground up in C.
