I licensed a 6800 Basic from Microsoft back when it was a partnership. This went in to the DRC190 system (see http://louise.hallikainen.org/BroadcastHistory/index.php/HallikainenAndFrie= nds ). It had line numbers, so we wrote a "precompiler" that allowed for long variable names, named subroutines and no line numbers. It output a file that could be downloaded into the DRC190 where it ran as interpreted basic. The good ol days!
