How reliable were the early LEDs? When did they start to get used in high reliability applications? I remember getting a rack of memory for a PDP-10 that used LEDs because the normal lights burned out all the time. That was back in the early 80s when real computers had lots of lights. I think LEDs were pretty new then. (at least new to me) The best reliability story I heard (many years ago) was about installing another trans-Atlantic telephone cable. They used tubes long after transistors were out. They knew how long the tubes would last. They didn't have much data on transistors yet. -- These are my opinions, not necessarily my employer's.
