Also, the SX wimps out (currently) at 16 MHz. This reduced bandwidth reduces the price. There is another (shudder) _marketing_ reason. Intel wants the SX to _kill_ use of the 286 chip since second sources exist for it; so, they want everybody to become totally dependant upon Intel Corp. Of course, in Real (DOS) mode a 386SX will be blown away by one of Harris's 200 MHz 286. BTW, Motorola is trying the same thing with the 68040 and 88000. The big difference, howsomever, is the Motorola's chips work right the first time, and no changes are needed to "fix" the chip and break someone's system (see i486 and the EISA bus- Intel "fixed" the chip to favor IBM and hurt the EISA manufacturers). Yes, I'm paranoid, but then, I am a motorcyclist. :-) :-) -- John R. Campbell ...!uunet!lgnp1!penrij!soup (soup@penrij.LS.COM) "In /dev/null no one can hear you scream"
