Since then, we've made more than 7,000 commits and massively expanded Woxi's feature set. So it's well worth another try for anyone who tried it back then!
You now fully support version 1.0. IIRC, the first version of Mathematica I used back in early 1993 was 2.1 soon followed by 2.2, which was useful for a couple of years. How much extra work is it to reach full compatibility with that version? (I had used MathLink at the time.)
