> Most lisp machines were specifically targeted at developers A bunch of Lisp Machines were directed at production, not developers. From Symbolics there were special models for that and also smaller "delivery system" versions of the operating system. For example American Express had a bunch of Lisp Machines as checking complex credit card transaction, Lucent had Lisp Machine nodes in a network switch, NASA had Lisp Machines monitoring video camera streams of rockets from Space Shuttle launches, Symbolics sold many graphics systems to TV studios, etc. > while smalltalk at Xerox was more targeted at office productivity. Is that true? Xerox had an office system running on the same hardware, but written in Mesa - unrelated to Smalltalk. Xerox had the CIA as a main customer for the Smalltalk machines, using an application called 'Analyst'... https://ethw.org/Oral-History:Adele_Goldberg https://ethw.org/Oral-History:Adele_Goldberg 'But our big commercial involvement was with the CIA.' > Interestingly enough Xerox hired the BBN team that made lisp machines, and the Xerox star was made to run lisp as well. BBN made a Lisp in the 60s, from where some developers went to Xerox in 1972/73. Before Lisp Machines existed. BBN Lisp was renamed Interlisp and was supported by both companies. Xerox developed Interlisp-D for Lisp Machines and BBN put Interlisp on an internal research computer.
