SC109 is a modular backplane bridge for RC2014 and Z50Bus. It contains both RC2014 and Z50Bus compatible backplane sockets, allowing both card types to be used together.
It can be connected to either a Z50Bus socket or an RC2014 bus socket, or it can be used on its own.
The backplane has 3 RC2014 compatible backplane sockets and 2 Z50Bus sockets. Some of the USER signals can be connected or isolated between sockets using jumper shunts.
