I just ran the original software restore on my wife’s old Snow iMac, prepping it to give it away (yes, it’s getting upgraded to at least 10.3 😉 )
It booted from restore in OS 9 by default, and the registration was great – the line of the day was during the network connection dialog, one of the options was:
“I am not ready for the Internet right now”
Some days, me neither little iMac. Me neither.
