Hi,
the C62 is perfectly fine, it just that you can't plug your motors in, you'll have to cut the plugs off and probably solder direct to the board.
The C10's are very simple boards. With screw terminals they are flexible. Note that it has no relays or other circuitry for a spindle, you will
have to make that stuff or add it. If you do get some get at least two, that will match the C62 as far as IO, but better get three. Then you can
have all three of the ESS port in action.
