Maybe start by telling us what it is & who made it. A very old computer?

You are looking for a schematic, not a datasheet. Schematics are difficult to come by, and this board looks like it's got a few custom ICs on it.

Those boards are all over the internet and all over the lot in price. The cheapest I found is one in Israel for $250 on ebay.

I would try contacting Nikon directly and see if they can offer any tech support.
