In an earlier post I said that the Duff device was in VAX BSD source, and caused diagnostics when recompiling the kernel. Well, on being challenged by Chris Torek, I found it in Gould specific UTX source, specifically in sel/in_cksum.c. But the point remains - the Duff device was found to be a performance win on a Gould machine, which, while considerably simpler than a VAX, is hardly a RISC. Andy "Krazy" Glew.
