The 32016 was one of the CPUs that inspired the ARM, because its performance was so terrible: it was not able to make good use of the available memory bandwidth. (There wasn't a 68000 second processor because its interrupt latency was too bad to drive the "tube" interface.) http://chrisacorns.computinghistory.org.uk/Computers/ACW.html https://en.wikipedia.org/wiki/Acorn_Computers#New_RISC_architecture Tony. -- f.anthony.n.finch <dot(a)dotat.at> https://dotat.at/ Malin, Southeast Hebrides: Cyclonic 4 to 6.
