I'm an old Amiga person rather than Atari one so
every so often I get
an urge to go buy an Amiga 4000. Instead I fire up my copy of E-UAE
running AmigaDOS 3.9 and the urge goes away. It runs some old games
better than my A500 ever did and I can run the AGA stuff my older
machines never could without massive modifications.
Even the demos? I doubt you can play with a Video Toaster :o)
