Submission + - ChipWits FORTH is Open Source. A Peek At 1984 GameDev. (chipwits.com)
To celebrate the game's 40th anniversary, the team behind the new Steam reboot of ChipWits (including its original co-creator Doug Sharp, also of fame for the game King of Chicago) is announcing the recovery and open source release of the original game's source code, written in the FORTH programming language, for both Mac and Commodore 64 platforms. Recovering data from 40-year old 5.25" and 3.5" disks was a challenge in and of itself, and most of the data survived unscathed! It's interesting to read the 40-year-old code, and compare it to modern game development.
