well the LC-II runs at 16 mhz,

The crystal on there is at 25 mhz,

LC-II could benefit from this because there is no FPU socket, even the color classic has a fpu socket.

the Classic II could benefit from a FPU upgrade… but does not have a pds slot.

and the classic II runs at 16 mhz, Not 25 mhz.

very strange! 8-o
