We have a poorly-designed interface between a minicomputer and a frame buffer which destroys a particular chip once every couple of months. The chips it eats are 74S151's. Our local hardware person says that these particular Schottky chips have not been produced for 8 years and he can no longer buy them. Does anyone know of a distributor who still sells them for certain (in Canada is best; anywhere in North America is fine)? Does anyone have a cache of them that they no longer have any use for? I know that fixing the interface board is the best long-term solution, but we hope to have abandoned that particular host within a year so we'd like to avoid spending much time and money on it if we can keep it operating by just replacing chips as they die.

Well, it turns out that someone has been telling our hardware person tales. Someone found a source of supply for them in Toronto; someone else found ones that had been manufactured as recently as 1980. So we don't have a problem anymore. I was impressed with the number of people who responded, and their helpfulness. Thanks to those who replied and those who looked in their IC stocks and didn't find anything. USENET was certainly a good way to reach a large number of the right people fast. Dave Martindale
