The market is just now rapidly expanding. The following are the ones that I am aware of: Levco Transputer (up to 4 transputers w/4MB apiece on each NuBus card) (619) 457-2011 (~10K fully loaded) Mercury Computer (a high performance RISC based machine w up to 8MB memory) (415) 847-2025 (~$20-25K total (?)) TI MicroExplorer (a powerful LISP machine on a NuBus card) (800) 527-3500 (~$12K for the board w/basic software & 4MB, ~$22K w/8MB and extensive software development tools) YARC Systems (CRAY spelled backwards. Powerful CPU, but strange and small memory structure.) (818) 889-4388 ($4400 when memory is available) Usual disclaimers: I've never worked with any of these machines. Personal opinion after evaluating them for my application (Computer Vision and AI problems): The Mercury has the highest performance, but the TI is also powerful and better suited for AI and vision. phil...
