Running the emulator on any Arduino (without the KIM Uno PCB)
Actually, the software will run on any Arduino, it does not need the PCB. Just compile the source code from the project site. Without a physical keyboard and LED display, it will only let you use it over the serial port of course. You can choose between two 'Modes' though. Mode 1: use a terminal program such as puTTY (9600bps) to look at the six digits like they would be present on the physical hardware, or (Mode 2:) just press [TAB] to switch the KIM-1 to its normal serial mode operation. In Mode 2, the KIM-1 ROM operates a bit differently in terms of keystrokes. See the http://obsolescence.wix.com/obsolescence#!kim-uno-summary/c1uuh">project web site for details.
