1820-0092 1 of 10 nixie driver.

Hi I needed to replace the nixie driver on one of my HP counters. These are a real pain. They are hard to find and if I want one, I have to buy 10 at $10+ each. These are frustrating because there is a TTL part that does exactly the same thing. It blanks the display for values above 9 and takes a TTL level input. The part is the 74141. The only problem is that the logic levels are inverted and wired differently. I piggy-backed stacked a 7404, 74141 and a machine socket with some wire and hot glue. The 74141s are also hard to find but many can be found on ebay at a resonable price. I'm quite pleased with the result because I'd moved the failed digit to the last location that rarely gets used. It would only display even numbers for odd. Now they all work :) Dwight
