Hello, Everyone This may be a little off topic for this thread, but here is a link to a picture of my Dad working on a device called a "Megabit Link Exerciser." http://www.afolkey2.net/gallery2/main.php/v/Ulrick1/MomAndDad/Dad/Dad-012a.jpg.html If I remember correctly, said device is an early, and very slow, modem.
