I need help arranging the diagram properly.

Lilith is in the Wikipedia.  "1977, Lilith" is in Ivan's diagram.  
According to Wikipedia, the machine was developed '78-'80.  Either '77 
is too early or Wikipedia is too late. 

Ideally time should progress downward in the diagram.  Some corruption 
is evident but not particularly harmful.  For example, Kronos Research 
Group appears above Lilith.  The rank constraint in DOT might correct 

Was Medos written in Pascal?  Modula-2?

Thanks,                           ... P. L.
