The Soviet-era ITS1-A is an even more bizarre tube, but there seem to be more of those floating around. I have a 6-digit ITS1-A clock from one of the designers here, and a couple of the single-tube demo boards that the VTA made a limited run of a few years ago. Some things that seemed bizarre in the early 60's jump-started whole industries - for example, the primitive integrated circuits designed for the Apollo space program led to modern IC technology. Display devices had a similar explosion of types and designs, but very few of them had much impact. Nixies (defunct except for hobbyists), Numitrons (defunct except for very few niche applications), VFD, LED and LCD are really the only major ones I can think of (and 2 of those are defunct). It may be that the nimo was designed for applications where the high voltage was already available as part of some other component. IEE did sell power supplies, but that seemed to be more for evaluation purposes than to put into actual production gear. Speaking of odd combinations, I believe the type 6977 VFD was designed as a logic level indicator for vacuum-tube computers. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
