As it came with unoriginal joysticks hardwired, I decided that I wanted to install joystick ports that were compatible with Atari\/Commodore joysticks.<\/p>\n\n\n\n<p>I also wanted to get rid of the RF modulator as well as the internal power supply.<\/p>\n\n\n\n<p>I found that the built-in PSU supplys 5 volts to the main board and as far as I can se it can provide a maximum of 1.6 amperes. I found a suitable external powersupply and tried feeding the main board with it, that was a success so I discarded the built-in PSU.<\/p>\n\n\n\n<p>After a short search for G7000 composite mod, I found several articles describing how to do it. I chose the simplest one that works with my TV.<\/p>\n\n\n\n<p>I did not want to destroy the RF modulater in case my composite mod did not work correctly so I took a floppy-power-connector from an old ATX power supply as it has almost the same size as the original plug that goes from the RF modulator to the main board.<\/p>\n\n\n\n<p>The colors in the original plug are as follows:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Yellow wire \u2013 Ground<\/li>\n\n\n\n<li>Red wire \u2013 Video signal<\/li>\n\n\n\n<li>Brown wire \u2013 5 volt<\/li>\n\n\n\n<li>Black wire \u2013 Audio signal<\/li>\n<\/ul>\n\n\n\n<p>With the floppy power connector it became:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Red wire \u2013 Ground<\/li>\n\n\n\n<li>Black wire \u2013 Video signal<\/li>\n\n\n\n<li>Black wire \u2013 5 volt<\/li>\n\n\n\n<li>Yellow wire \u2013 Audio signal<\/li>\n<\/ul>\n\n\n\n<p>The joysticks were hardwired into the computer, but were actually attached to the main board with plugs. I cut the wires and soldered them to DB9 plugs I inserted in the chassis.<\/p>\n\n\n\n<p>In my G7000 the wire colors are as follows:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Black \u2013 Ground<\/li>\n\n\n\n<li>White \u2013 Up<\/li>\n\n\n\n<li>Yellow \u2013 Down<\/li>\n\n\n\n<li>Orange \u2013 Left<\/li>\n\n\n\n<li>Green \u2013 Right<\/li>\n\n\n\n<li>Red \u2013 Trigger<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>This is a quick draft, later I will add pictures and diagrams I recently acquired a Philips Videopac G7000, but it was in fairly poor condition.
