Yeah, I don’t think I did anything but upgrades, but I might have tested various configuration options for the screen and sound card back and forth. I was using an early Pisound for the soundcard initially, which needed upgrading, so at one point I was unloading and loading modules and reconfiguring the GPIO by hand, although that in itself shouldn’t have affected any stored configuration options I would have thought. But I do remember switching between different 'Kit’s and things of that nature.
