(I apologize if this has been covered before...I just got back to town.) I'm looking for references to the RS6000's POWER microprocessor. Magazine articles, conference proceedings, or even hype would be useful as long as they dealt with the processor and/or processor/memory -- I've got the usual run of "UNIX World" and "IBM Release Notes" stuff. It's probably too much to ask for, but does anyone know of a POWER Programmers Reference Manual? A couple of immediate questions concerning POWER itself: 1) How many integer units? 2) How many floating point units? 3) Anyone know the reason for the 128-byte cache line size in the D-cache? Seems large... 4) Details of scrubbing -- is it done on the memory hardware itself, by the DCU's, or what? If this has been covered previously, I'd appreciate it if someone would just mail me a summary. Thanks. -- Mark Campbell mark.campbell@ncrcae.Columbia.NCR.COM

I just started looking at an IBM publication our local salesman gave me. It's about 200 pages split between hardware and software 'papers'. So far it looks pretty good. "IBM RISC System/6000 Technology" 'Copies of this book, SA23-2619, can be obtained from the local IBM branch office.' Rick Grandy BCS, Richland
