Berry 314A Trunk Test Set

It’s blue, it’s a box, and it sends MF tones. The famous blue box dates from the early ‘70s, Berry didn’t offer this product until 1979. It’s not the namesake of the famous “bluebox”, but I can’t help but wonder if the folks over at Berry knew what they were doing when they decided to put it in a blue box.

This lovely little device is powered by an RCA “COSMAC” CDP1802 microprocessor.
