EndBASIC is a free implementation that is written in Rust. It's more focused on the DOS based BASICs than VB-styled ones.
I (author of EndBASIC) have been busy with other stuff since this made the front page last time and have not had a chance to touch the project for the last few months, but I do still have plans to grow it.
Just earlier today, and out of coincidence, I added "email subscriptions" to the front page of the project -- just in case any of you want to get notified when a new release comes out :) If you /do/ subscribe, you may get... 2-3 emails a year, and help me gather how many people actually care about this.
It's great to see someome doing side projects just because they want, not as a way to make some business on the side.
It's very cool, although my first BASIC was QBasic from DOS 5.0, so this is more "primitive" than what I remember BASIC being. Keep up the awesome work.
