DRÄPPEL Posted November 9, 2005 Report Share Posted November 9, 2005 http://www.ucapps.de/mbhp/mbhp_sid.pdfApply power to the module and check the voltage level between pin IC1:Vdd(28) and IC1:Vss(14) - it must be 12V for the 6581 SID, 9V for the 8580 SID.IC1 is the SID chip, Vdd(28) is the pin marked 28 on IC1 in mbhp_sid.pdf, Vss(14) is the pin marked 14 on the same chip, Vdd and Vss are printed next to the corresponding pins too.Hope this helpsCheers Quote Link to comment Share on other sites More sharing options...

DRÄPPEL Posted November 9, 2005 Report Share Posted November 9, 2005 I forgot the part that says "Mount all the parts with the exception of the three ICs." Don't fry your SID! Quote Link to comment Share on other sites More sharing options...
