I have versions 1.0 and 2.7. Both of which have a copyright of 1981. These are the disk based versions of course and not the cartridge version. The version 2.7 has a handful more free bytes. Is there a newer version than 2.7?
Oh yeah, been meaning to ask, why has there never been a XEX of the Microsoft BASIC II cartridge? I know it dropped some functionality to disk, but the 16K cartridge gives you an additional 3K of programming space.
