Notes:
Note 1: SID (6581 or 8580) not listed here - you have to take it from an old C64
Note 2: If you don't find an 1MHz oscillator for less than 3 EUR, don't buy it and connect
        the SID clock pin to the core module, J7:SO (PIC Pin RC2(17)) instead.
        This workaround solution brings the same results, requires just one interconnection 
        more and will be documented under http://www.ucapps.de/mbhp_sid.html
Note 3: Instead of 78L12 you can also use a common 7812... the 78L12 is just the smaller one
Note 4: The C64's in the grey surface may contain a newer SID (8580) which has to be
        supplied with 9V instead of 12V --- in this case you have to use a 7809 instead of 7812!!!
        And you have to replace the C1/C2 caps (470pF) by 6,8nF caps!
Note 5: Audio Plugs not listed here - 2 are necessary, for Audio In and Out
Note 6: 15V/100 mA transformer not listed here
Note 7: outside europe the BC547 is hard to find (Mouser has them), the 2N3904 is a good replacement
        But note that the outer pins (E and C) are exchanged - you have to upturn the
        transistor to get the E, B, C pin matching with the PCB
Note 8:	Dimensions found after the capacitor values correspond to fit SmashTV's layouts 
    	(13DIA-5LS=13mm diameter casing with 5mm lead space between holes for the pins)

PCB: (Required jumpers shown in Red here)


Construction Tips:

First install your jumpers: (locations shown in Red)

As you can see with some of the resistor and jumpers, they won't go in
easily after the sockets are installed:
