OHIO Scientific Challenger 4P

When the C4P was launched, Ohio Scientific said that it was a giant step in the world of the home computers. It was twice as fast as an Apple ll or Commodore Pet and more than three times as fast as a Tandy TRS 80. However, despite its technological lead, the C4P and other Ohio Scientific computers always suffered of a lack in efficient software and attractive handbooks. For this reason, very few third companies built cards and peripherals for the Challenger series. So, the C4P didn't withstand to the competition of the Apple II and II+ version which appeared 4 months later. However, Ohio Scientific sold it until 1981 as a business oriented system.
