An "Apple Macintosh implementation of Prolog". Requires "Mac OS 7.5.5 and later". It claims to need at least "4 Megabytes", which isn't possible on a Macintosh Plus, but it still seems to run when given less, such as 1.5 Megabytes. One problem is that it will not work if you give the program all the available remaining memory, you have to set its partition size smaller, leaving some free. (The benchmarks table lists a Macintosh Plus, which is why I thought it might work in the first place.)
