Infocom was the kind of text based interactive fiction in there hayday. Their at the center of one of my alltime favorite bits of computer gaming honestly.
Includes two unreleased (though incomplete) games they were working on before, that too my knowledge have never been leaked in any form before and little public documentation existed on them.
@tim, how much theoretical storage does allthe.codes have? 
While massive, in that its the source code to numerous games. These games are tiny, being pure text with almost no visual assets. Im sure Tim can find room.
My 7z archive of the git repos is under 50mb.
Currently ~ 15GB. If we get just the git repos out of there we should, for sure, put them up on allthe.codes!
(Also friendly reminder that allthe.codes registration is open for all)
