As we get older we get wiser. It’s just part of the deal. We have all heard the expression that knowledge is power, but power can also be corrupting. Sometimes, it’s good to get a reminder that as smart or as knowledgeable as we think we might be there is always something new to learn.
I had one of those moments recently when I looked closely at a computer called the “Super Brain” that has been sitting out at a computer museum. I had never really spent much time with this machine but when I did I found out that it had a “Here Is” key. It’s enough to make you do a double-take. At first I thought it was a joke.
The most common keyboard joke in existence is the one about the “Any” key. Back in the days when computers ran text only operating environments (like DOS) it was common practice to put a message such as “Press Any Key To Continue” while waiting for the user to finish reading. The joke is that some people would literally spend time looking on their keyboard for a key marked “Any” rather than just literally pressing any key on the keyboard.
I had to do research on this key and discover what it is used for. It turns out that it is used for radio teletype identification. The key transmits a code 22 characters long that identifies to another teletype machine just which machine is sending a message. In other words, this old computer has a key that means only something in the context of a technology that is even older than itself.
The joy for me was that the day I discovered the “Here Is” key was a great reminder of how wonderful it is to learn something new. It’s almost self proclaiming (if only it were a “Here It Is!” key) and now, most likely, you too have learned something new today. For the Silo, Syd Bolton.
