The card has more than 2 layers.
The RAM chips are no problem, they don't need to be toshiba, most
manufacturers have a chip with the same configuration and specs, and many
laptop PC memory boards have them.
ExpressPCB can make those boards in no time, but we would have to send
them diagrams.
I Have another idea. Usually, you can stick memory chips one on top of
the another, solder most pins between them and wire the "chip select" pin
to the corresponding signal in the memory socket or controller. I have done
that before in an old laptop PC.
