One similar dialect you might try is MicroLISP for Commodore 64. With some digging you may find a disk image of it to load into an emulator. One of the first things that struck me was lack of strings, instead you use multi word symbols which are allowed with functions like EXPLODE and IMPLODE to work with them. It's not so bad once you get used to it. However, not being able to do decimal math does actually make BASIC of the era feel more powerful. That said Lisp has the clear advantage for code organization as you've got functions so you can have clean separation of program pieces unlike Commodore BASIC.
Thank you for these videos. Your enthusiasm is clear and pleasant to hear. These windows in the past, into a future we lost are very interesting!
Interesting video format 🤔
