Awesome Nixie Tube Calculator - Friden 1115

Whoohoo!! I found this at a thrift store for $5.00. Of course I plugged it in and was shocked when all the tubes lit. Initially I was going to harvest them for a clock project, but as usual I just did whatever little repairs it needed and now it sits on my desk - and I use it.

This was made for Singer by Friden in the late 60's-early 70's and is comparatively rare in the Friden line. The nixie tubes illuminate a bright orange, Joy.. :)
