Psion II I/O Board


Just a quick update on the Psion II I/O board. The basic board is now finished and has 1 8-bit output and 1 8-bit input port and everything works as expected.
The next job is to add two L293D quad half-H drivers (which makes 4 full H-bridges for 4 motors) to drive the 4.5volt Lego motors.
