An old TDD with Futaba simplified linears

Here are some photos of a Telecommunications device for the deaf(TDD) made by American Communication Corporation around 1986. It uses an acoustic coupler and Futaba simplified linear switches. Its most appealing feature is the large character vacuum flourescent display (VFD). It is powered by 6 AA batteries, and yes it works!
The case was closed with plastic rivets. I cut the rivets to separate the two case halves. I replaced the rivots with panel nuts and screws. T
