I don't know if this is of any interest to anyone here, but 1999 is 18 years ago, so maybe it counts as old? Over on nextcomputers.org various users had found a backup of next68k.org which included a wget of the old source http://nextftp.onionmixer.net/next.68k.org/otto/html/pub/Darwin/PublicSource /Darwin/index.html So I found a copy of Rhapsody DR-2, the last binary version of this Mach 2.5+4.4BSD and after a day got a kernel to build. Another day and I had it interfacing to the driverkit to load drivers. After a post on reddit someone gave me a link to some kdx p2p network, where they had a Darwin 0.3 toast image. using what I learned with Darwin 0.1 I got the 0.3 to build as well. I uploaded a bunch of stuff here: https://sourceforge.net/projects/aapl-darwin/ although it seems to not let me upload the toast images themselves. I did slam together a minimal Darwin 0.3 qemu image that can sort-of boot to single user mode. It's not even slightly useful, but it does show that it works. https://sourceforge.net/projects/aapl-darwin/files/qemu-images/Darwin03_qemu 090_24_4_2017.7z/download
