Plug in the 68000 processor and minimal glue logic. To test if you build this part of the circuit correctly, add 10k pulldown resistors on all 15 data lines of the processor. Power on the board, and verify with an oscilloscope that A0 operates...
There are three kinds of processors that are compatible with the Nomad board, all of which are slightly different: The 68000 is the "classic" 68000 processor. This processor draws more power than the 68HC000, and cannot be clocked as fast. ...
