I may be misremembering then - it was the disabling of the math co-processor I was thinking of. Just remember the concept of dumbing down a chip for marketing reasons.

>The main problem I saw with the 386SX was that it was made to be pin-compatible with the 286 -- which usually meant that systems built with it are likely to be "held back" by the motherboard and associated hardware (i.e. basically you couldn't expand beyond 286 capabilities in terms of memory and associated operation modes.). Of course it's not too different from 8088 (in that it was basically a 16-bit 8086 sitting on an 8-bit bus)...

>And then there was the 80486SX... where it was essentially a 80486 with built-in numeric co-processor disabled. You could upgrade to get the numeric coprocessor by installing a 487 -- which was not just the coprocessor but a complete 486. However, you didn't end up with two 486s -- as the installation of the 487SX would disable the 486...

Though a good deal is too strange to be believed, nothing is too strange to have happened.
- Thomas Hardy

Half the harm that is done in this world is due to people who want to feel important. They don't mean to do harm-- but the harm does not interest them. Or they do not see it, or they justify it because they are absorbed in the endless struggle to think well of themselves.

-- T. S. Eliot
Democracy is two wolves and a sheep voting on what to have for lunch.
Liberty is a well-armed sheep contesting the vote.

Pardon him, Theodotus. He is a barbarian, and thinks that the customs of his tribe and island are the laws of nature.
