I was in the lab that did that. :) :) https://en.wikipedia.org/wiki/Texas_Instruments#Artificial_intelligence For the Explorer, a special 32-bit Lisp microprocessor was developed, which was used in the Explorer II and the TI MicroExplorer (a Lisp Machine on a NuBus board for the Apple Macintosh). (The money for the chip came from DARPA.) In general, PLT semantics (denotational, operational, axiomatic) of computing is substrate independent, but in UCNC there is the beginning of "intrinsic" semantics (physical, experiential). @philipthrift -- You received this message because you are subscribed to the Google Groups "Everything List" group.
