From the project
My Motorola 68000 & 68302 processors (+ SIO, PIO & MFP boards) for the RCBus ecosystem.
I had a chat with Steve to get his approval for me to take his SC701 backplane design and alter it for my own needs.
This backplane I've put together has 2 additional slots - making 8 in total. It also incorporates parts of Steve's SC719 digital I/O board to give 8 debug LEDs and 8 tactile pushbuttons. I also incorporated his SC729 CompactFlash module (with electronics by Tadeusz Pycio - www.vtsys.pl) as well.
