    • Merlin - history http://www.merlintec.com 1983: Pegasus (Logo Machine) 1986: Merlin 2 1993: Merlin 4 2003: proto Merlin 6
    • Merlin - overview Neo Smalltalk Plurion: External memories RISC42 RISC42 RISC42 RISC42
    • comparison base start funding Plurion, Neo Smalltalk COLA PC, Linux, Sugar 1999 (1983) 2001 (1970) 2005 $70K self financed Donors $5M NSF $20M initial Tiny royalty
    • comparison testing Open source content In a few months Since 2005 Since March 2007 yes yes mostly Pay per use ? volunteers
    • comparison Multi cores sharing security groups HydraVM Linux SMP? Viewpoint sync Tea Time Telepathy / Tubes Object extensions Islands Bitfrost
    • Conclusion The children can ’t wait… to have a community we need a standard platform right now pieced together from what exists. Sugar can be that platform. But this approach won ’t take us very far into the future… we need to develop stuff we can control.
