So, the essentials of a tape relay center were a receive bank, a send bank with a monitor reel for each location, and a message repair area. This equipment and rolls and rolls of tape, gave us our nickname.
Frenchman Emile Baudot configured this code in the 1790s. There was no practical application for it until the turn of the 20th century.
This is the original Baudot code. By the 1900s, American inventors began constructing equipment which could make a practical application of the code on punched paper tape.
Using the Murray code, this is how letters appeared on the paper tape we used.
These machines are somewhat similar to what we used.
This plug board was the last Univac model without an internal hard drive. These spaghetti plugs were quite colorful.
The reps from Sperry Rand were glad to show us this board as they checked for tightness and then ran tests off-line. It had just a few kb of RAM.
This is as close to our relay station as could be found. Most photos of the Navy and Air Force relays didn't have the exact equipment we had.
Grass Mountain relay was at least 4 times larger than the picture shown.
Before the Vietnam War, civilians with a security clearance ran this relay in Hawaii. At 100 wpm, messages would accumulate quickly as shown here.
Stepping on the tape caused problems as did kinks in messages being sent.
