mcd was having trouble locating a cable for his Macintosh Portrait Display recently and the problem has cropped up before, sooo . . .

I'd snagged a clearanced Griffin Technology 21" Two Page Display/Portrait Display cable when I liberated mthe Portrait at Tekserve back when both were fairly newly passe, but I was getting a 21" two page image compressed horizontally onto the Portrait's single full page screen.

I called and spoke to a very knowledgeable engineer who said they had probably mixed up the cables during packaging and they could send a replacement when they could find one. It became clear to him that I was in a hurry to play with my new toy, so he half serioustly suggested building an adapter . . .

. . . then he noodled out the pinouts for me right then and there. ;D

I'll try to get the get it back together correctly and document the pinouts for the hack when I get a round tuit or more quickly upon request. She may be ugly, but she sure can cook and the 21" cables are a lot more common than the Portrait cables.
