SC107 v1.0 (www.scc.me.uk) Modular backplane with mode 2 interrupt daisy chain for RC2014 Features: - Modular design - Expandable with additional sections - Edge mounted expansion plug and socket - Pins 38 and 39 wired as an interrupt daisy chain Documentation at [www.scc.me.uk](http://www.scc.me.uk) There is an alternative design with a through hole mounted expansion socket. See projects SC112 and SC113. Project SC113 has jumpers to allow pins 38 and 39 to be isolated, wired straight through or used as an interrupt daisy chain. This seems a more flexible solution than this dedicated module. See also SC105 and SC106.
