I got my hand on quite a bunch of Developer CDs. From 1994 to 1999. And among thos were the Rhapsody CDs. Developer Release 1 and 2, even the version vor PC Compatibles. Anyways, I tried to install DP2 on my PowerBook 3400c. It's not mentioned in the list of supported Macs, but I tried anyway. It worked fine so far, but after finishing the intallation it rebooted and booted off the CD again and did the whole installation all over again. I tried to remove the CD, but it won't boot at all without it. Too bad. Gonna try on a 8500 or 9500 again... I'll keep you informed.
Here are some Pictures of my try (looking interesing anyway):
