Thank you.
Great news for retrocomputing.
It’s Microsoft BASIC btw.
Another situation where many people will be surprised to find out it wasn’t already open source. It’s kinda comical to imagine them caring to keep that source code a secret decades after its deprecation.

I feel like this is very common and it makes it much less comical. There are cases where sources were leaked, but still not legally available, afaik
