TVisitor Posted February 17, 2007 Share Posted February 17, 2007 Hey all, Working on system with multiple games stored in FLASH, and I see that the Atari 2600 is a 5V system. I can get a 3.3V or 2.7V Flash that is 5V tolerant on it's inputs (i.e. on the Address lines) but what happens if I feed 3.3V (or even 2.7V) into the data bus of the 2600? Is this enough to be read as a valid high, or is it not going to work? Thanks! Quote Link to comment Share on other sites More sharing options...

TVisitor Posted February 18, 2007 Author Share Posted February 18, 2007 Thanks batari... What about the TIA and the 6532? Quote Link to comment Share on other sites More sharing options...
+batari Posted February 18, 2007 Share Posted February 18, 2007 Thanks batari... What about the TIA and the 6532? I don't know, but considering that all TIA and 6532 reads/writes must be handled directly by the 6507, it probably doesn't matter. Quote Link to comment Share on other sites More sharing options...
