"Pete" Marwick - funny. KPMG (Peat Marwick) had an interesting history with Macs. I remember back in college in 1990ish we used a Mac program that would graph general relationships (Logical Data Structure, LDS, was its name). We used it in an advanced database class. Peat Marwick either commissioned it or wrote it... I remember their name on the 'about' screen.
Saw this in Singapore - but quite expensive though. Is this the one for collection?
