I'd been curious about this one since it was released in the early 80's. I wrote an emulation in python to satisfy my curiosity. (https://github.com/deadsy/py_z80) My general conclusion was that the hardware wasn't good enough (monochrome competing with the ZX Spectrum's color) and that Forth didn't offer enough advantages over BASIC to warrant significant usage. It's an interesting design though, and it's good to see how they built their Forth system in an 8K ROM.
