I was doing a search as I found a dead 170 with a video card in it. It attaches to the memory slot and has a S video cable that is long enough to reach out the back. It has two types of ram on it. I am wondering is it ram for both video and powerbook memory? Does it need drivers? It says 140 and 170 so that would be cool to put in one and see it put out to TV or whatever. If anyone knows specs or has more info on the Lifetime Memory Products Inc. card for the PWRBK 140/170 I would love to see it.
