ganchan Posted March 20, 2008 Report Share Posted March 20, 2008 in the c64 power plugs there are 2 free pins.i'm thinking to use this to connect a 14v modified psu with the same c64 male plug. so i can use the original or the 14v one.but i know that 7805 must not stuffed into the core and 2 pins must shorted. a) can i leave the 7805 soldered when i connect the c64 PSU?b) the optimized psu circuit will receive the Voltage form the SID and CORE when the 14v mod it's plugged. this will be bad for noise/dropping etc.?i'm doing some test but more prof. member can suggest me ho do it (without a switch better) i've NO space.regards.G.

stryd_one Posted March 20, 2008 Report Share Posted March 20, 2008 Err, I don't understand? Quote Link to comment Share on other sites More sharing options...
DenDer Posted March 20, 2008 Report Share Posted March 20, 2008 Well i think i know what ganchan means. On some of the c64 psu's you got more than four pins inside the connector maybe he wants to use these since they are unconnected for his other PSU....am i right??

stryd_one Posted March 20, 2008 Report Share Posted March 20, 2008 Well, that part I understand...but what for? Quote Link to comment Share on other sites More sharing options...
DenDer Posted March 20, 2008 Report Share Posted March 20, 2008 That's a good question indeed Stryd maybe Ganchan could be/should be more clearer....maybe he wants to connect a washing machine or a hair dryer. :-\ :o ;D :D ;) Quote Link to comment Share on other sites More sharing options...
