If Juergen can't make it boot I don't want anything to do with it. That's a 5-Aarons-with-devil-horns difficulty level
Dunno where you heard that he couldn't make it boot, according to his Alto dev blog - which is apparently only up when he's online, hence why it wouldn't show up on archive.org - says he got it up and running well enough to boot run some Alto games, and even for the ethernet card to receive packets. I'll see if I can't mirror it on my webspace.
