Generations

Different generations of processors used variant pinouts of the S1 socket; processors were not necessarily compatible with a socket even if they fitted mechanically. Processors designed for the later S1g2 socket would not work in an original S1, aka S1g1, socket, although older processors were compatible with the newer socket. There is also S1g3 and S1g4.
