Well, if anyone has any spare video memory chips, I certainly could put them to good use. I've tried everything to get rid of the SimasiMac bars on one of my SE/30 logic boards (cap job didn't do the trick), but until reading this thread, I thought it was a lost cause. Now it would seem a video chip swap might do the trick. But alas, I don't have any spares handy.
So again, I'd love to give some a try, if you could spare them!

There are plenty more on that Mac II graphics card [] ]'> PM me your address and I can post them to you. (I am in Ireland so it could take a bit of time to get to you, about a week to US)

Unfortunately due to limited equipment, I can only snip them off , so the pins wont be full length. You will have to snip the pins on your end too leaving as much as the pins as possible. Then its only a matter of lining up and soldering.

I am not sure what success you will have, as this se/30 was still booting even with the 'jail bars'. So the problem had to be on the video side.
