bosone Posted November 11, 2004 Report Share Posted November 11, 2004 now that the interconnection test works, but none of my sid seem to work, i wonder if these voltage i read between GND and SID socket are correct:pin   V1    02    03    04    05    56    07    08    59    010    011    012    513    514    GND15    516    517    518    519    520    021    022    023    024    025    5    26    027    028    12(using 6581, mios 1.7 and sid 1.6)core is working correctlythe problem is that when i power up, all i hear are electric transients. i also tried with sidplayer, but no note are heard... just very small volume clicks and blips...beside this the sid was gettin really really HOTby the way, could the transistor on the audio output of sid be fused?? is the only thing that's lets (apart the fault of all my sids) Quote Link to comment Share on other sites More sharing options...
moebius Posted November 12, 2004 Report Share Posted November 12, 2004 Hi,You can find pin list (these don't refer to sid pins, but pin names) from main.asm of the sid interconnect test and then use sid schematics for cross reference.Bye, Moebius Quote Link to comment Share on other sites More sharing options...
bosone Posted November 13, 2004 Author Report Share Posted November 13, 2004 no, you either misunderstood or i asked the wrong question:these are the voltages that i read on SID socket when i load the SID MIOS application, not the interconnecting test!the interconn. test is goodbut the sid still won't play...i'm using mios 1.7, sid 1.6, hardware mods for mios 1.7the core is working, i see the text on LCD and i'm able to use the control surface Quote Link to comment Share on other sites More sharing options...
moebius Posted November 14, 2004 Report Share Posted November 14, 2004 Sorry.. I didn't understand..Well, "power" seem ok.. and I don't know what to expect from other voltages, other than measuring osc or data/address lines, doesn't make any sense ;) (Did you check that in interconn. test lines also were in default state, when not selected.. of course you did)It's very unlikely that all your sids are broken..Do you use onboard oscillator on SID? If that is the case, you could try clock supplied from core.Also it's worth trying to change BC547 on sid output.Bye, Moebius Quote Link to comment Share on other sites More sharing options...
