Mr modnaR Posted September 5, 2006 Report Share Posted September 5, 2006 i'm pretty sure the optimised version is the one to go for. Quote Link to comment Share on other sites More sharing options...
Therezin Posted September 5, 2006 Report Share Posted September 5, 2006 That depends. If yu bought your boards from SmashTV or Mike, it should say on the board something like MBHP_CORE_V2 or MBHP_SID_V3. This indicates which versions of the connection boards you have, from which you can find out which diagram to follow. What do yours say?

TK. Posted September 5, 2006 Report Share Posted September 5, 2006 The one which is showed at the http://www.ucapps.de/mbhp_sid_old.html page under the headline:MBHP_CORE -> MBHP_SID_V2 interconnectionsBest Regards, Thorsten. Quote Link to comment Share on other sites More sharing options...
leelinn Posted September 5, 2006 Author Report Share Posted September 5, 2006 tnx TK!ok that link works for one to one interconnections.But for multiply interconnections? I need to know the exact interconnectsion between 2 Core modules & 2 SID modules ;)lee Quote Link to comment Share on other sites More sharing options...
TK. Posted September 5, 2006 Report Share Posted September 5, 2006 There isn't a big difference, just duplicate the picture (both cores are controlling the SID modules independently)Thereafter you can do the MIDI link and power connections like explained in the optimized PSU schematicsBest Regards, Thorsten.

leelinn Posted September 6, 2006 Author Report Share Posted September 6, 2006 hi tk,tnx again!!! ;)my SIDs have both the 1Mhz osc.: i have to remove them a make this connection >> "SID clock to Core::J7:SO PIC Pin #17" ? Quote Link to comment Share on other sites More sharing options...
TK. Posted September 6, 2006 Report Share Posted September 6, 2006 YesBest Regards, Thorsten. Quote Link to comment Share on other sites More sharing options...
leelinn Posted September 6, 2006 Author Report Share Posted September 6, 2006 YesBest Regards, Thorsten. :'( :'( :'( i hoped you said "NO. it's not necessary. You may choose. If yr pcbs have mounted the oscillator you can keep it"......but if not...i'll remove the OSC.tnx again Thorsten ;) lee Quote Link to comment Share on other sites More sharing options...
TK. Posted September 7, 2006 Report Share Posted September 7, 2006 It's better without the external oscillator, see also http://www.midibox.org/forum/index.php?topic=5748.0Best Regards, Thorsten. Quote Link to comment Share on other sites More sharing options...
Altitude Posted September 7, 2006 Report Share Posted September 7, 2006 it's a simple fix, one wire to the one of the pins on the core (J7) to one of the legs from where the old osc was (look at the trace, it goes directly to the CLK pin, its pretty obvious) Quote Link to comment Share on other sites More sharing options...
