This family of calculators was built around RPN, a Forth inspired language.
The thing is that language tokens were not exactly interpreted in the classical way, they were converted to address of routines in the 512K ROM (or RAM for more dynamic objects)
Programming language, OS and hardware were very closely coupled.
