I agree that thing is most certainly a LED display. Too thin to be a panaplex, Try to connect 5V in series with f.ex. 1k8 to various pins and look for any light. Those old LED's are very sensitive. Too high current and they are instantly gone.
The number 670 may refere to an old red display on prpopto's site. Have You any idea of how old Your display might be or where it comes from? It looks like a prototype part not in production. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
