mackomester Posted December 17, 2014 Report Share Posted December 17, 2014 Hi everyone! I'm just done with my PIC Core and SID R3A, and I have a question to you guys. Basically everything went well, Mios works like a charm. I have the sid testtone app uploaded, no problem, I have the signal on the output. The question is that the Sid chip goes hot.... After a few secs I hardly could hold my finger on it... In the meantime the sound was fine. It's a pulled 8580R5 (5187) from my own C64, was working perfectly. Is it normal? Should the Sid be fitted with heatsink? What is the average normal temperature? Thanks in advance! Ps: sorry for starting a new topic:) Quote Link to comment Share on other sites More sharing options...
Altitude Posted December 17, 2014 Report Share Posted December 17, 2014 (edited) What voltage is being supplied to the SID? 8580 should be powered by 9V DC. They get warm but not that warm Edited December 17, 2014 by Altitude Quote Link to comment Share on other sites More sharing options...
Hawkeye Posted December 17, 2014 Report Share Posted December 17, 2014 (edited) The 8580s, when correctly provided with 9V, can live without heatsink (and probably already did so for decades! :smile:) You can fit one, nevertheless (i´ve got a few pictures, if you are interested). With heatsink, mine get warm, not hot, i´d say around 40-50° celsius or so. Many greets! Peter Edited December 17, 2014 by Hawkeye Quote Link to comment Share on other sites More sharing options...
mackomester Posted December 17, 2014 Author Report Share Posted December 17, 2014 (edited) Hey lads! Thanks for the answers! Here is the result of the past few hours: I've probably fried the sid, I don't know how. With the connection test I've measured only around 1,7-2,2V on the D6-D7 pins of the sid when inserted, 5V when pulled out. Then I checked the resistance between this two pins (out from the socket) and there was about 320 ohms resistance. Strange thing, the testtone was worked.... I had another (the last....) 8580, which has the proper voltages of all pins.... Now the other one is back in the C64, I'll test it tomorrow. I have no idea what was wrong... Ps: the actual sid is just warm:) Edited December 17, 2014 by mackomester Quote Link to comment Share on other sites More sharing options...
