"The Sparcle is an experimental 32-bit microprocessor chip developed in 1992 by a consortium of MIT, LSI Corporation, and Sun Microsystems. It was an evolution Sun's SPARC RISC architecture with features geared towards "large-scale multiprocessing".[1] The chip was manufactured by LSI." https://people.eecs.berkeley.edu/~kubitron/cs252/handouts/papers/sparcle-micro-final.pdf From what little I can find I believe this prototype CPU / system was based on Linux.
