Altirra is probably the best Atari 8bit emulator out there
Atari 800 Win is still a very good and competent Atari 8bit emulator
STeem is THE emulator for emulating Atari ST and regulary updated
Hatari is also a very good Atari ST emulator
Emulator Zone is a good place for downloading lots of different emulators
For emulating Vic 20, C64 and all the other Commodore computers, VICE is the emulator to use
For emulating Amiga, WinUAE is the best emulator to download
Try Colem for emulating Colecovision
Else Freeze SMS does a good job emulating Colecovision
Most of you are aware of Stella (Atari 2600) i belive? I post the link, in case.
