I've been working on creating a logo image for this site using a series of Burroughs 5971 Alphanumeric tubes to spell out the letters of the title.
As a proof of concept, I simply wired the correct cathodes together to manually spell out the characters. This would have worked if I had a power supply that could supply enough current. I am using one of these as a source (not shown in the video) and several 9V batteries connected in series to power it. However, I quickly discovered that it would only illuminate a few random letters when both halves were connected. In the video below, you can see me connecting "TUBE" and "CLOCK" with mixed results. (Generally, all that is shown is UBE / CLOC)

Moral of the story, I need a better setup to accomplish this!
