I once saved a pile of interesting looking paper from being burned in the fireplace. It turned out to be a granted patent application, the UK version of Gene Myron Amdahl et al. of (what later was called) the 360. It described in great detail the instructions and this new thing called microcoding (although I don't rememer which words were used in the patent). There were appendices with full schematics and a microcode dump. These days you can get PDFs from the US patent office of the thing, if you manage to find its numbber (which I don't have at hand). -Olaf. -- ___ Olaf 'Rhialto' Seibert -- The Doctor: No, 'eureka' is Greek for \X/ rhialto/at/xs4all.nl -- 'this bath is too hot.'
