Top view. Blue SBX connector in center, dual CAN pluggable screw terminals in lower left corner, RS232 DB9s on left edge.

Bottom view (DS80C390 socket side). The processor socket is on the 'back' side of the board. This enables an ICE to be installed while an SBX card is also installed. You can still probe the labelled headers on the top of the board while using an ICE.

With prototype SBX1 option card installed.
