Intel Corp says that it has resumed shipments of the 80486 microprocessor after a month’s hiatus while it fixed the bug in the chip’s floating point processor. Not all customers have yet received good parts, but the company says it is still on target to ship tens of thousands of 80486s by the end of the year. Customers are being offered replacement parts on a one-for-one basis, and the previous version is still available for prototyping and evaluation because the vast majority of applications will never fall foul of the bug.
