ISAAC is a set of ports of Julian Gollop’s Rebelstar to the SAM Coupé and MSX.
These are in the public domain. The source code will be released when it’s better commented. I’m also planning a port to the Enterprise 64/128. Note that Rebelstar is a trademark of Namco. For this reason, I have chosen the name ISAAC (after the computer that you must destroy in the game) to refer to these ports.
