Open sourcing CROBOTS was something I should have done a long time ago. I always thought I'd get back to it, but life, kids, job, & other projects seemed to always come first. Thanks to Neil Fraser for finally prompting me to put it up on Github under an open source license. Neil also converted the manual to HTML.
I have had a lot of fun playing with the original or modern clones of corewars and robotwars.
There's an interesting article in an old issue of Computer Gaming World  which discusses RobotWar and includes a BASIC listing for a tournament-winning robot, pretty cool.
