Free FullWrite Professional™ Document Processor
Dave Trautman's site allows one to download a full copy of the last version of FullWrite Professional. If MORE 3.1 was the ultimate outliner (OmiOutliner Pro 3.x may rival it now), then FullWrite Pro was the ultimate wordprocessor. Like MORE, it's now available for free.
It apparently runs in the OS X classic emulation mode, though it gives a FOND error message that can be ignored. I remember FW Pro as a monster -- it required megabytes (at least one) of hard drive space and maybe 1-2 megabytes of memory. It really strained my SE/30. It was also buggy when I used its full features in the earlier versions, but it was an astounding wordprocessor. It was also a quite decent outliner.
