What is the voltage, current, and style of the lamps used on the PDP-8 series of computers? I recall seeing 14V, 28V lamps both mentioned, but no current ratings. In checking out Chicago Miniature (http://www.sli-lighting.com/cml/electronic/index.cfm), it looks like they have quite a few lamps that might fit the bill. http://www.sli-lighting.com/cml/databookpdf/2-47.pdf is the PDF file I was checking.
