Found these inside a lot of broken Saturns I got from a friend who's been storing them for years. I couldn't get 3 of them to work and the 4th I was just too lazy to test. Anyways, take them all for $30, or trade me something kinda cool and Sega-ish. I took these pics last month and am listing them only now, thus the old date in the photo. -Segasonicfan
I'm sorry, I'm not sure what this question means. I'm pretty sure these are meant for 21 pin Saturns. They are different from all the ones I've seen. I usually see the blue modchip boards with a little square chip in the middle and red + blue wires. But I'm sure there are others out there as well. -Segasonicfan
ASSEMbler is right. The blue mod boards your talking about are later revisions where they tried to skimp on costs. That's why they lack a timing crystal and one ribbon socket (You directly plug the mod board into the motherboard instead)
