Hi folks....

I am at a standstill. I found everything I need for my Mystic upgrade but for the 68 pin, 512K 70ns VRAM SIMMs for the 575 logic board.
I have posted every place I can find, talked all day to countless apple and non apple memory folk, but still nothing.

I think I am stuck. If any of you can direct me to a few places to look that would be great. I am new at searching out places they might be hiding. And, if someone has a couple for sale, please do contact me:

Any suggestions, or work arounds appreciated.
