since the first BlitzBasic... I checked the white ring binder that one came with and the copyright shows 1990. It shipped with a dongle for copy protection... I had to use on a friends Amiga 2000 for a while since the dongle didn't work on the A500. I'm pretty sure Mark's fix was just to eliminate the dongle. I missed the first year or two of PC blitz, those were my C++ days.
