IBM 7094
if u play funny monkey game (gorilla tag) then you must know of daisy09. an exploiter who plays the song daisy bell. and the song daisy bell is very cool and the reason why is that in 1961 the song daisy bell was played on the IBM 7094. and it is not used anymore. but you can still see the console in person!
dude i wish IBM 7094 was not put out of use.
