Apple LC 520 edge connector pinouts?

As per subject, does anyone happen to know the system board edge connector pinouts for an Apple LC 520? I picked up a few useful boards which were destined for recycling from someone yesterday, and decided to save the Apple board too, more out of curiosity than anything (it's not obvious what machine it was from, but I'd noticed the '030). It might be fun one rainy day to try feeding it power - assuming I can find out what the power requirements* are, and assuming that the video signals (which would have gone to the built-in CRT's analog board) are something sane. [I have no VRAM module for it, but looks like it has a banks of 1MB and 4MB on the PCB, so perhaps the 1MB is for regular framebuffer, and the VRAM socket is only for expansion to allow higher resolution or color depth] * main power rails are likely possible to work out, but of course there will be soft-start and power-good type stuff to worry about. cheers Jules
