In the wake of revelations that IBM offered DEC some key chips last year, the company has now confirmed that it has sold small quantities of leading edge chips to several rival computer manufacturers, but insists that the sales were made solely to satisfy itself that its chips are still as good as anything out of Japan and can win in a competitive bid. Companies said to have taken IBM chips include NCR and one or two European manufacturers; IBM says the sales amount to less than $20m a year, and that it has no intention whatsoever of entering the merchant chip market.
