Hi
I recently started the Back to the Future Java project on GitHub:
https://mzattera.github.io/b2fJ/
which allows you to write and run Java programs on the C64.
In its present state, it works (obviously with some limitations, most noticeably speed).
However, it is only the first version, more a "proof of concept" than
anything else. I hope I can improve it and make it at least as fast as
BASIC
Feel free to take a peek and leave some comments.
Regards
Maxi
