che Posted June 17, 2003 Report Share Posted June 17, 2003 Hi All  :) I've got a problem with my SID-module. I just assembled my core and SID- module. I took my new friend , the multimeter, and tested the two boards. The core-module seemed to be ok, but my SID-module didn't give the 5 V at the IC 2 and IC 3. No power at all at these IC-sockets, the SID-socket gave a nice 5 V though.Does anyone know what could be the source of this problem?Which of the J2 pins should receive the 5 Volts from the core-module? Thanx, Quote Link to comment Share on other sites More sharing options...
TK. Posted June 17, 2003 Report Share Posted June 17, 2003 Hi Che,the power supply input pins for the +5V voltage domain are J2:Vs (ground) and J2:Vc (+5V). When you follow these tracks from the core module, to the SID module, to IC2 and IC3, with the probes of your multimeter you should be able to find the errorBest Regards, Thorsten.

che Posted June 18, 2003 Author Report Share Posted June 18, 2003 Thanx for the reply TK,I feel o so stupid! :-[ Are the pins of the ic 2 and ic 3 numbered in this way?1 *|-----|* 162 *| |* 153 *| i |* 144 *| c |* 135 *| 2 |* 126 *| |* 117 *| |* 108 *|___|* 9 If so… sorry to have wasted your precious time TK! Then there is nothing wrong with my sid-module, I’m just Stupid. Che :-[ Quote Link to comment Share on other sites More sharing options...

pilo Posted June 18, 2003 Report Share Posted June 18, 2003 You're not stupid! how many times I solder a connector in the wrong way (like the midi in and ou one), even with taking care about it? I think it's error that everyone make! ;) Quote Link to comment Share on other sites More sharing options...
Guest Xcen Posted June 19, 2003 Report Share Posted June 19, 2003 I haven't started my midibox yet but I must admit I once thought for a year that my midi keyboard wasn't working because I didn't know the INs needed to be connected to the OUTs :) Quote Link to comment Share on other sites More sharing options...
che Posted June 29, 2003 Author Report Share Posted June 29, 2003 thanx for your support ;)Everything is soldered together and I've got it all in a test-setup, with one wall adapter. Everything is ok, except the voltage between pin IC1:Vdd(28) and IC1:Vss(14) - it must be 12V for the 6581 SID- But it's 11,80!Does it matter?Che Quote Link to comment Share on other sites More sharing options...
TK. Posted July 7, 2003 Report Share Posted July 7, 2003 Hi Che,11.8V are ok, nothing to be worried about :)Best Regards, Thorsten. Quote Link to comment Share on other sites More sharing options...
