Are you sure it’s literally Forth? If so, can you share some keywords?
The closest thing I know of is HP 48 - not Forth, but quite Forth-like, and it definitely tought me a thing or two.

I've also seen ones that can be programmed in C, BASIC, and even Pascal. Again, magnets for my disposable income.
