So how would you handle the confusion of capturing apiece. For example
you move a white bishop across the board to capture a black rook.  You
remove the
black rook and set the white bishop in its place.

Being a chess players and computer nut for years an engineering friend
and I thought this out back in the days of the Commodore PET. For it to
go beyond having
entering the data manually. you would have to as a minimum have 12
unique peices identified. for the white side: pawn, rook, knight,
bishop, queen & king. and the
same for black side.  We did some experiments with the resister idea but
had some problems with the resistance of the conection.

What about these micro ID chips they  inject into dogs and other pets to
ID them?
