SC517 is a modular backplane that forms a bridge between the Z50Bus and the RC2014 bus.

This modular backplane section can be connected to any Z50Bus compatible bus socket, such as a modular backplane or the LiNC80 SBC1.
It provides one Z50Bus compatible card socket, three vertical RC2014 bus compatible module sockets, and one horizontal RC2014 bus compatible module socket.
The horizontal socket allows either an RC2014 compatible module to be connected or another modular backplane section.
