Intel started shipping 20MHz 386SXs by sorting the original 16MHz line, but went to a different line for 20MHz in volume (presumably different process - 1 micron?). The shortages in 20MHz 386SXs suggests to me that (1) the speed-sorting of 16MHz parts wasn't yielding well and (2) the new line didn't yield well either (or perhaps the new line didn't come up at all). > Will it burn out the board? Nope. But it might be real flaky. After the machine heats up, watch out. -- James R.
