It does not run Microsoft software at all, as far as I can tell. EhBasic isn't Microsoft Basic, ehbasic was written by Lee Davison. And this particular version was further enhanced (see github). And wozmon was obviously written by Woz.. not Microsoft.

There has been some discussion around this, and Lee Davison is no longer with us so that makes it more difficult. It appears from the source code that Lee's independent basic is highly based on Microsoft Basic. I'm sure it is no longer an issue, especially as Microsoft has provided a free license for Microsoft 6502 basic, but the licensing situation is not entirely clear.
