Altirra
a Atari 8 bit Emulator on the Windows/DOS platform
This emulator, written by the creator of Virtual Dub, emulates several models of the 8-bit Atari computers. This includes the the 800, 800XL, and 130XE versions. It has a lot of options, and compatibility is decent especially given the emulator's early stages. It also supports some copy protected games properly in emulation.
