nixie tubes

Thanks to a local electronics forum I managed to get my hands on some Nixie tubes. Two sets to be exact. One set came complete with the original driver circuit board which has some very interesting Russian made Nixie drivers similar to the venerable 74141 and 7441. I think they are pretty rare too....

Just the screen

Attaching an LCD screen to a pc is a pretty easy job. I am working on a jukebox that I wanted to a screen attached to. Although a HD44780 based LCD can be attached to the parallel port with almost no additional parts I wanted a more flexible solution, and I thought about microcontrollers...
