There were plenty, I have a small collection of them! Most of them, including HES’s “64 FORTH”, are heavily fig-forth based. The thing I really like about 64 FORTH is the SOURCE word, which shows you the source code (at least the portion of it that is forth) for each word, so when I mess with forth on the C64 I mostly use that one.
