@trag: is there any particular reason why the ICs are flip-flopped on the 256k SIMM?

How many layers make up the VRAM SIMM PCB?
I haven't looked at one in a while, but usually, the orientation of the chips is chosen to get the pins into convenient locations for board routing. So it might make corresponding address pins line up with each other nicely, or get all the data pins in the right place or something like that.
