Here lie some links to useful stuff, anything reasonably relevant to Atari TOS computers and the emulators for them..
RELATED LINKS:Patrice Mandin - The likeliest point of origin for any new emulator ports from SDL. This is of more interest to those lucky higher-end Atarians. Gnuboy and others located here.
Atari Shack - The download location of the ZX81 emulator, Specci 2.07, and the 2nd Life TRS80 emulator. Also some games for each system can be found there.
Cream HQ - Link to Cream SID and JAM multi-format music players.
Reservoir Gods - Godboy and Godlynes stuff lives here.
Atari 800 - Home of the Atari 800 emulator. Also comes in several non-Atari flavours.
Dead Hackers home page - Atari scene central, first for any breaking news about that fantasy SDL-based PS2 emulator for Atari!
Matthias Jaap - The location for STemBoy.
Flaysid - David Carrere's Flaysid homepage. (Not updated in a long time.)
Peter P.'s Pages (PeP) - The starting point for the Frodo and SMS Plus ports. Also the best place to look for any new stuff for the CT60/CT63.
WebKnox - Knox's site, which includes Intellivision Rom's, and hopefully soon, his new Atari-based emulation of that machine!
Pouet.Net - Get software image files from here. This is perfectly above board and legal, as it all refers to demo's and similar software in the public domain. When accessing the main page, search under the "Prods" menu for your chosen machine category.
