carsten_the_dane Posted May 2, 2006 Report Share Posted May 2, 2006 HiI have found 3 c64 now, hoping to find another one soon.My question is: Since the chips in the 3 c64s are different numbers, do i really need to use 2 power supplys for the midisid? I read somewhere that the old and the newer sid-chips uses different voltages.ThanksCarsten Quote Link to comment Share on other sites More sharing options...
TK. Posted May 2, 2006 Report Share Posted May 2, 2006 Hi Carsten,what do you mean with different numbers - different types (6510 vs. 8580) or different production dates?However, in both cases you can use the same PSU so long you ensure, that the 6510 gets 12V, and the 8580 gets 9VBest Regards, Thorsten.

carsten_the_dane Posted May 3, 2006 Author Report Share Posted May 3, 2006 Thats what i mean. I have 1 6510 and 2 8580 (maybe even 8581, i havent opened my newest c64, but its not the breadbox).So how do i make sure the get different volts. Thats what i mean, will i need to supply to different power supplies, or is it all taken care of in the design. How do i make sure that the 6510 gets 12v and 8580 gets 9v.Sorry if its a stupid question, im a complete beginner when it comes to electronics.Carsten Quote Link to comment Share on other sites More sharing options...
moebius Posted May 3, 2006 Report Share Posted May 3, 2006 Yes, It's taken care in the design.Look little further in the details of the MB_SID and Your PSU design.. and follow the instructions ;)Moebius Quote Link to comment Share on other sites More sharing options...
