Not really. Lucid took the money from Lisp sales and invested it into C++. Read it in Gabriel's book. > As it became practical to put enough gates on a single chip for a Lisp Machine, it would have taken a great deal of adroitness to make the transition, and that wasn't in the cards. TI developed a single-chip microprocessor. The later TI Explorer and the MicroExplorer were based on microprocessor CPUs. DARPA financed it for the 'Compact Lisp Machine'. Symbolics did the same - they redid the CPU as a microprocessor, the Symbolics Ivory. Many Symbolics machines were based on that chip: XL400, XL1200, XL1201, UX400, UX1200, MacIvory 1/2/3 and the NXP1000. Symbolics did three iterations of the CPU and had a full design of a RISC cpu ready.
