Directions: Step through the program already prewritten below (First "Burn Prom" and "Load RAM") . Set (check) switches S1 thru S8 as desired and observe how single stepping thru entire program causes LED's to illuminate in accordance with switch settings. Next type in your own program (starting at address zero) over the existing program. Burn Prom and then load RAM with zero's. Try writing a program that makes Bit 8 turn on all LED's. Though you have no bit wise operators you can test for >127.
The voltmeter can be connected to P1-1 thru P1-18 or TP1 thru TP5 and will sample the voltage at the end of each Single Step cycle (Read all Notes at bottom of spec sheet.)
