The contents of this archive were taken from an eBay auction of disks and manuals (no boxes) of two versions of Sub Battle Simulator.  One, from 1987, works on compact Macs like the Plus.  The other, from 1988, is meant for early color Macs like the Mac II.  Both had identical manuals but a different reference card and addendum.  The included box scans were found on the web and are believed to be from the first Mac version.

There is a still later Mac version of this game updated and published by Digital Illusions and Alliance Interactive.
