I got the Copy Cat electronic dump. I just dumped the low 7 bits, but those match my (now correctly arranged) visual dump. www.seanriddle.com/mp3005n

1.5 seconds after you turn the real game on, it flashes orange, red, yellow, then green while playing tones. This repeats every 9.2 seconds. The emulation is a little faster and flashes the wrong colors. It also doesn't work right when you press a button to start playing. I haven't debugged it enough to figure out what's going on there.
