I am looking for a detailed (good enough to read chip markings) image of a Mac IIvx motherboard. Images of the P600 and IIvi will not do, as it is precisely the differences, I want to see.
Specifically, I'm interested in the corner/edge of the board where the Cache and Tag RAM chips are located, and possibly the underside of the same region. I would like to know what parts Apple used for the cache SRAM and Tag SRAM. Also, there are a number of empty resistor positions in the region on the Performa 600, that I suspect are populated on the IIvx.
The Tag RAM will be the difficult component to locate, but there's a seller on Ebay who has tubes of 30 chips which are probably the proper Tag for sale. But I'm not sure. I'd rather confirm it before I spend the money.
