US industry commentator John Dvorak again highlights Intel Corp’s strange machinations with the 80486 variants – an 80486SX is just an 80486 with the on-chip maths co-processor disabled, an 80487 is a full 80486 with the pins wired up differently, and points out that while the reason Intel has made these moves is to stop second-hand 80486s flooding the market when people upgrade, anyone that upgrades an 80487, which automatically cuts out the 80486SX, and doesn’t pull out the latter chip and sell it must have money to burn.
