I seem to remember this being discussed many years ago, but I can't find it. Anyway, there's an Altair on epay right now with a CYCLOID faceplate. If I remember correctly, this is just a replacement plastic insert that was sold simply to "freshen up" an Altair where the original had worn badly, as so many did. I've done a fair amount of searching but I can't find an ad or other reference to the product. Does anyone recall the time period? I would assume it was at least a couple of years after the introduction of the Altair. 78 or 79? A pointer to an advertisement or one of those "new product" paragraphs that many of the magazines did back then would be most helpful.
