KIM-1 Clock

Over on hackaday.io, [Arduino Enigma] posted the code for his clock that runs on a KIM Uno (the KIM-1 clone we mentioned late last year ). Although the KIM Uno has a few demos preloaded (including Microchess and a scientific calculator), all of them take some interaction. The clock makes the KIM Uno a more dynamic desk display since it does something useful without any user interaction (once you set the clock, of course). The project shows the code stored in ROM, but you can’t directly enter the program into ROM (which is really EEPROM on the host Arduino). The trick is to enter the address (that is press AD and then 0, 4, 0, 0) and then mash down the reset button for about a second. Then you can press DA and enter the hex codes provided (pressing + after each byte). Since the code is in nonvolatile storage, you can start it at any time by setting the time in RAM and execu...
