I bought my MacIvory from David Schmidt about 4 years ago. At that time, it was my understanding that David only owned the maintenance contracts from Symbolics as well as the ability to sell Symbolics hardware. The intellectual property for Genera was owned by John Mallery (http://www.csail.mit.edu/user/926 http://www.csail.mit.edu/user/926)
