panamajoe #1 Posted December 13, 2005 i just installed the AV Mod from 8bitdomain in my PAL-4 switch Atari and it only displays a black and white picture... i´m sure i did everything right... anybody any ideas what went wrong........ Quote Share this post Link to post Share on other sites
+SpiceWare #2 Posted December 14, 2005 The PAL TIA has a different pinout than the NTSC TIA. Being that 8bitdomain is in Dallas Texas I bet the AV Mod is for the NTSC Atari. Quote Share this post Link to post Share on other sites
Spirantho #3 Posted December 14, 2005 Incidentally, if you need an NTSC Atari or a modded PAL Atari let me know... I've got a spare Heavy 6er here I've not got around to modding yet, and loads of other flavours. Quote Share this post Link to post Share on other sites

And if so... where can i get NTSC TIAs??? Quote Share this post Link to post Share on other sites

You need to use a different mod, or adapt the 8bit mod to the different pinout. Quote Share this post Link to post Share on other sites
Spirantho #6 Posted December 16, 2005 The NTSC and PAL TIAs are completely different pinwise. You'd need a little circuit to sort it all out and even then I'm not sure what would happen. PAL and NTSC Ataris are quite different inside. Quote Share this post Link to post Share on other sites
