There isn't a whole lot that has to be done to hook a IIGS up to a VGA monitor, not like the serious mods required to hook up my C128 to a VGA monitor. But what it boils down to is soldering a jumper from pin 3 to 15 on the bottom of the logic board. I can't solder like I used to, my hands shake too much lately, so I got some solderless breakout plugs one HD15 VGA, and one DB15. Instead of jumpering the logicboard, I can accomplish the same thing externally can't I? Pin three on the DB15 to the 15 on the HD15? I have the upscaler that will convert the 15hz signal from the IIgs to the LCD I'm going to use, but the input is HD15.
