Short explanation for some who dont know it yet.
Apples Lisa was the predecessor to the macintosh, heavily influenced by the Xerox Parc research machines, it to my knowledge still used Smalltalk as operating system and programming environment.
Might be an interesting addition for a new core, now that the OS is out in the wild (not that there are any games on it, maybe collossal cave is ported, dont know)
