They also admitted the 16032 was basically compute bound and the 32 bit bus only gained 25% more performance. The marketing department loves it, however. As long as they can say 32 bit bus, who cares if it's faster? I have no particular axe to grind with National's micros. I think their instruction set is nice and their MMU one of the best available (although that isn't saying much). It's a shame that Motorola thinks the way to high performance is to crank up the clock rate. It's really expensive to provide the kind of memory needed by a 16 MHz processor. trying not to be biased, -- Phil Ngai (408) 982-6825 {ucbvax,decwrl,ihnp4,allegra,intelca}!amd70!phil
