I don't have mine handy right now, but tried it out on the web emulator.
http://www.neocomputer.org/kenbak/kenbak1-JS.html I just pasted the code below into the memory loader. It seems to be running, but do you have a description of how how you meant for it to work? When it runs, and I hit a button, the lights blink for digits I have not already selected. output 7 is off, and if I hit button 7, the program stops. Looks like you're pretty good with the Kenbak Code! -- Ricky
