InterMac Bumper Ships v1.1 / Bootable System 4.1 disk image for vMac or real Mac 128K / DSK image
Mac OS 1.x - Mac OS 4.x
Note: This does not run under Mac OS 6 and even under Mac OS 4.x you will notice the Finder gets all F*** up when you exit the game, so you'd be better to reboot immediately after you're done playing.
Emulating this? It should run fine under: Mini vMac
