[GreenKeys] Torn Tape Relay Transmitter project

[Nick England]

Lately I've been wiring up cables and connectors and debugging hardware.
Here's the initial test of my tape transmitter components - six TDs singing
and dancing together. Actually three channels, each with two TDs which
operate in ping-pong fashion under control of a Message Identification Unit
which inserts numbered headers at the beginning of each message.

Here's an earlier video that shows the headers inserted into three messages.
