Configuring the 80487SX socket
If the 80486SX is soldered directly to the CPU module the
socket will already be configured for an 80487SX.
If an 80486SX is installed in the socket it must be removed
and the socket reconfigured, before the 80487SX can be
installed. The socket is configured by a four pin jumper
block and two position switch alongside the socket.
