David Murray posted on the comp.sys.apple2 newsgroup recently that he has wired up a Sony PSone 5? LCD screen to work as a display for an Apple IIgs. The display isn’t perfect due to being lower resolution than the Apple IIgs display, but it’s quite readable, especially compared to composite output.While we don’t necessarily advocate trying this at home, here’s what David says he did: “In order to get the display to come on it needs to sense +5V on pin 10 and I ran a wire from the 7805 voltage regulator on the inside of the screen to pin 10 on the connector…. Also, the LCD only has one video ground, so you have to tie the red, green, and blue grounds together from the IIgs. Otherwise everything is pin for pin.”
This is a very cool bit of geekdom!
