This is really neat. Not so long ago I happened upon a disk image containing FIG-Forth for the Atari 8-bit computers and had some fun playing with it on an emulator for a couple hours - poking registers to toggle on the hardware sprites, dumping the display list and modifying it to create custom display modes, etc. Unfortunately this was some stripped down version in a single EXE file that was missing the editor or anything stored in blocks on the disk, so it wasn't practical to really write anything interesting with it.
