Racal-Norsk built a lisp machine based on the Norsk Data multi-port processor (ND-570 and ND-550) and MIT ZetaLisp (circa 1984/5). It had a high res monitor and custom keyboard with 3 button mouse. The system was referred to by the sales department (who lived somewhat in their own fantasy world) as the KPS (Knowledge Process System - this was at the time of the "AI" boom). Various parts of the company were of very different levels of competence. In light of the PC era that was about to bloom, perhaps the companywas a white elephant in its strategy of being a multi-user super mini. The hardware systems people at Racal Norsk struggled, but in their defense the sales force (that had been prematurely employed and bonus motivated) forced through sales by arm twisting tactics, so that the hardware support people (who were far from up to the job) were obligued to install Norsk systems they ill understood, and before the zetalisp system had been developed to even alpha stage. A chronic case of trying to run long before being able to walk. But the software engineering team did a great job going through MIT ZetaLisp with a tooth comb. A prototype software system was just working in the labs by the time the company was brutally shutdown (a complete surprise to the workforce).
KSP-10 systems were imposed (disasterously) on the Open University and the University of Oslo. I lost my Symbolics 3600 when it was sacrificed to the OU bargained (quite resonably) to get a working lisp machine.
