dcreatorx Posted November 24, 2005 Report Share Posted November 24, 2005 Should I use the voltage rectificators on other modules once I used it on the PSU ? Thanks. Quote Link to comment Share on other sites More sharing options...
moebius Posted November 24, 2005 Report Share Posted November 24, 2005 Hi,Yes. You can remove core regulator and put a bridge between pin1 <-> pin3, but leave the SID modules as is.Bye, Moebius Quote Link to comment Share on other sites More sharing options...
dcreatorx Posted November 24, 2005 Author Report Share Posted November 24, 2005 I can or I should . . beacause I did and now i don't get the right voltage . . . oh god things are turning black ! :-X Quote Link to comment Share on other sites More sharing options...
moebius Posted November 24, 2005 Report Share Posted November 24, 2005 Hi.Should (Must) :)Ok. The PSU puts out +5VDC, right? You have read the schematics carefully and noticed, this goes to core J2? (remember the polarity)..If plugging the core to PSU drags voltage lower, it could be a short somewhere in the core.Bye, Moebius(p.s. Do the core debugging without MBSID connected - and yeah, remember it still needs the regulator and that +14VDC from the optized PSU circuit) Quote Link to comment Share on other sites More sharing options...
dcreatorx Posted November 24, 2005 Author Report Share Posted November 24, 2005 Ok I'd disconneted the SID module and now I get the right voltage on the core . . . but the main problem now is the 14 VDC output. I can't get it out . . It's well connected but .. don't know . . any comments about ? Quote Link to comment Share on other sites More sharing options...
TK. Posted November 24, 2005 Report Share Posted November 24, 2005 Are you using the PSU of an "old" C64 (which contains the 6581), or of a C64II (which contains the 8580)?Best Regards, Thorsten. Quote Link to comment Share on other sites More sharing options...
dcreatorx Posted November 24, 2005 Author Report Share Posted November 24, 2005 Hi Thorsen, I think it's the first version. Quote Link to comment Share on other sites More sharing options...
TK. Posted November 25, 2005 Report Share Posted November 25, 2005 Hm.... which voltages do you read exactly? I mean, sometimes people measure 13.9V, and then they think that this could be a problem... but it's just within the allowed tolerance.If the core gets a voltage much lower than 5V if the SID module is connected as well (lets say 4V or even lower), then there must be a short circuit on the SID board. Check it visually, sometimes small solder clumbs can cause such an effect.Remove also ALL ICs when doing such checks, thats very important!First try to get the Core module running like described in the SID Walkthrough. Once it works, you know, that the problem cannot be located at there.Best Regards, Thorsten. Quote Link to comment Share on other sites More sharing options...
dcreatorx Posted November 25, 2005 Author Report Share Posted November 25, 2005 Ok Thorsen . . . now I have the right voltage at the core and sid module !!! I will debug the other SID module, I'm sure that it is the probem.Now . . . can you tell me if the PC midi-port is the 16 pins yellow one ? Is it called gameport/midi as well ? Thank you moeb and thorsen . . . you're the best. :)EDIT : Could I buy a Gameport/MIDI to MIDI (DIN) cable ? That's the way you upload the SID app and the S.O to the PIC, right ? You still the best :D Quote Link to comment Share on other sites More sharing options...

You still the best :DYellow 15 pin D-connector sounds just like standard gameport/midi. Go ask for "a soundblaster midi cable" from your local computer store (and compare prices if you can! Some stores have a huge profit margin in these)You'll need that midi connection for uploading MIOS and SID app to the core.Thanx, Moebius Quote Link to comment Share on other sites More sharing options...
dcreatorx Posted November 25, 2005 Author Report Share Posted November 25, 2005 Ok perfect ! I'll go right tomorrow ! I'm so glad about the voltage. I'll need to fix the other SID module . . something is f***ed in there.Well I just want to say : You're the best, I'll come back soon arround here for bring some pictures !
