Shawn Jefferson Posted July 24, 2003 Share Posted July 24, 2003 Ok, I had some time the last week and put a PAL Antic chip in one of my 800XLs. It seems to work except I am getting a open paranthesis "(" in the 38th byte position on the screen all the way down. If there is data in memory for the 38th position, I get some sort of ANDed/ORed data instead of what should appear (so it IS reading from memory, but getting corrupted somehow.) I ran various programs and it seems that no matter the mode, the 38th byte position is always corrupted. This makes for interesting text scrollers. If a screen does not use a mode that loads 40 bytes from memory, then no corruption is seen. The NTSC chip worked fine (I tried it first), but I think I will try it again and see if it is still working. Anyone have any suggestions or insight? I'm thinking it may be a problem with the Antic chip itself maybe? I don't have another for testing at the moment. Quote Link to comment Share on other sites More sharing options...
jindroush Posted July 24, 2003 Share Posted July 24, 2003 Are your memory chips socketed? I would try to swap them for another set, just for a test. Maybe the PAL Antic has slightly different timing (especially the refresh timing) and is corrupting your memory. I still think that NIR-Pal is nothing like Real-PAL Wouldn't it be cheaper and more useful to buy real PAL Atari? I'm assuming you'll have to have multi-norm tv, what may be a problem in States.
