"Reduced Instruction Set Computers." IEEE Computer > Society 1988. Bob Colwell answered these items, which inadvertently but correctly includes valid criticism of my own simplistic offering. I take issue with Jon's rather petty outrage that an employee would repeat what his employer said. Don't forget our context here. A participant asked for a short answer. I ran across one (required reading, you see) which was the shortest one I had seen. "Fine for a Press Release"? I clearly labelled it as such, and my affiliation is given. From the variety of responses, there seem to be a number of definitions. Wouldn't it be interesting for someone to gather all vendor's definitions and publish them here? We might then get closer to the real (in silicon) truth. Then again, we might just get marketing's press releases. And I do like tenpura and smores. -- ------------------------------------------------------------ Ron Voss Motorola Microsystems Europe, Munich mcvax!unido!mucmot!ron CIS 73647,752 my opinions are just that, and not necessarily my employer's ------------------------------------------------------------
