Dunno if anyone knows this off the top of their heads, but what’s the  
absolute oldest version of MacOS that SDL will run on?

Assuming a recent version of DrawSprocket and InputSprocket, it is  
possible to run on older OS versions. The oldest version I have tested  
against is 8.1. I have heard rumors of people running GLTron on 7.6.1,  
but haven’t verified this.
