Neon logic

I came across reference to a file, LAMP.ZIP, you posted briefly for the Classic Computer list back in '99. Would it be possible for me to get this file? I'm fascinated by the idea of making counters, logic gates, and memory elements using neon lamps, but repeated google searches reveal very, very little hard information (other than there were such circuits). Also, I've read a few pages on early calculators (such as the Anita) using something similar to neon lamps for logic gates and ring counters, though the pictures lead me to believe they are actually 4-lead gas triodes or thyratrons of some kind. Do you know what these beaties actually were? Finally, I've repeatedly run across mention that neon device switching is slow, but how slow are they? You assistance is appreciated! -RLN
