I have that demo, and very well it works too. The 8580 has 'combined' waveforms that aren't in the 6581, so if you set oscillator 3 to one of them at a slow frequency, set and reset the test bit on that oscillator and read the oscillator 3 waveform register, the 8580 will always (deterministically) reach the same value which is different from the 6581 value.
