Note 1: SID (6581 or 8580) not listed here - you have to take it from an old C64
Note 2: Instead of 78L12 you can also use a common 7812... the 78L12 is just the smaller one
Note 3: 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 4: Audio Plugs not listed here - 2 are necessary, for Audio In and Out
Note 5: 15V/100 mA transformer not listed here
