I think I have a disk with some early versions of BASIC for the Mac on them but it's hard to search using "Mac" and BASIC" on Google to do some research.  I have a 400k disk that has both on it. 

What is the earliest version of MS-Basic for the Mac?

What versions are available for MacBASIC?  I saw the one version on Macintosh Garden but I have a newer one, it seems. The about screen says it's for a specific person to use so I'm going to take some pics and post once I remove the name. It's beta.

Thanks.
