I am very very old. Been retired over 15 years. Formerly was a "techie" or "geek" or such names. Then I was involved in computer communication protocols. That's how computers talk to each other. I'm amazed at the technical complexity of some of the posted INSTRUCTABLES. I have been know to use a soldering iron sometimes.
