bradd1978 Posted August 9, 2014 Share Posted August 9, 2014 Hey, Just recently installed this in my Colecovision and its unreal. But I wanted confirmation on whether the F18A uses the DRAM that requires -5V? I've been googling and don't see anything, I'm probably blind :-P Ultimately does this set me up to be able to mod the system to only use a +12v/+5v power supply and ditch the big brick? :-) Quote Link to comment Share on other sites More sharing options...
+5-11under Posted August 9, 2014 Share Posted August 9, 2014 It doesn't use the DRAM chips on the CV main board. It has its own memory, on the F18A board. The F18A uses +5V only as an input. Quote Link to comment Share on other sites More sharing options...
bradd1978 Posted August 9, 2014 Author Share Posted August 9, 2014 Wow! Thats an even bigger bonus just using the +5V. Looks like I'm ditching the brick :-) Thanks 5-11! Quote Link to comment Share on other sites More sharing options...
ApolloBoy Posted August 9, 2014 Share Posted August 9, 2014 You could probably ditch the -5V rail as well but I believe the Roller Controller uses it so you may want to build an additional circuit for -5V. Quote Link to comment Share on other sites More sharing options...
