Ha ha! We actually learned on the old Kleinschmits in school, then "upgraded" to the KSR's in the field!!! Hey, nothing like 75 baud data rates, right?! Did 5 punch paper tape for awhile as an aux device on our Streamliner system. Even though my security clearance is long gone, I sure would like to visit a commcenter and see what they're doing today. Good memories working with great people! Thanks for the chat.
