The first truly portable personal computer was released on this date in 1981. The 25-pound Osborne 1, sold by the Osborne Computer Company, with two floppy drives, a five-inch screen, was a big success, selling 10,000 units a month.
The Pony Express began mail delivery on this date in 1860. The first mail pouch contained 49 letters, five telegrams, and a variety of papers. A rider would switch to a fresh horse every 10 to 15 miles; each rider rode a leg of 75 to 100 miles. Seventy-five horses were needed to make a one-way trip between St. Joseph, Missouri, and Sacramento, California, a distance of 1,800 miles. At an average speed of 10 miles an hour, the Pony Express could cover the distance in 10 days.
The Pony Express, as it came to be known, had only been in operation for about 10 weeks when Congress authorized construction of a telegraph line to stretch between the Missouri River and the California coast. Once the telegraph connection was completed, the Pony Express became obsolete, and it folded in October 1861.
Times have changed, and it's fun to look back.
