Amiga RGB to VGA cable
Hi All,
I want to make my own RGB to VGA cable for my A1200, I'm planning on using the guide below: http://www.ntrautanen.fi/computers/hardware/misc/a4000_vga_cable.htm But I'm confused which wires connect to which pin on the inverter IC. Has anyone else made a cable using this method? I'd be grateful for any help on which wires go to which pins on the inverter. Cheers Ben |

EDIT, misread. I see why you need 5+v for now. |

Thanks cpiac64
Would you use a capacitor between the ground and power supply wires as suggested in the guide? If so, would a 0.1uF 50 Volt Ceramic Capacitor be ok? Thanks for your help, whilst I'm pretty good with a soldering iron I'm a newbie when it comes to understanding electronics. |

0,1uF is ok
