Midnite Posted August 12, 2007 Report Share Posted August 12, 2007 I have completed a core and sid build. The core worked fine yesterday after I applied a 9v500ma power to it (I failed in my attempt to convert my c64 power supply). I was even able to load mios and the lcd worked good too. Today after I got some new parts I tried to use the optimized power supply plans from TK and my core stopped responding. The 7805 got extemely hot, but it did the same yesterday before I used a 9v pwsply. I put the 9v pwsply back on and nothing. I replace the 7805 and still nothing.Please help Quote Link to comment Share on other sites More sharing options...
doc Posted August 12, 2007 Report Share Posted August 12, 2007 Please measure the voltage before and after the regulator and give us the values.Unplug the PIC before and also measure the voltage for the PIC (Pin 11 & Pin 12).Please also have a close look on your board for ans bridges, shorts or bad solders.greetsDoc Quote Link to comment Share on other sites More sharing options...
Midnite Posted August 12, 2007 Author Report Share Posted August 12, 2007 I think I revived my core. Grounding out pin #1 on my pic brought it back to life. I checked the voltage on my c64 psu and the 9v side is dead. Time to search for a new psu. 12v 1a for a core and sid (6581) right?Thanks-D Quote Link to comment Share on other sites More sharing options...
