Challenger 1P

The Challenger 1P is a personal computer produced by Ohio Scientific, and was advertised as being the first microcomputer with all of the primary components integrated onto a single circuit board (including the keyboard). The computer is encased in an all-steel enclosure, with a beige top plate and a chocolate brown base. It features a QWERTY-style keyboard on top underneath the aluminum branding badge, and ports on the rear for composite video output, cassette tape input/output (as RCA connectors), a serial port with an accompanying switch to choose between 110 and 300 baud, a TTY connection, and a BNC connector that may allow for wiring an additional composite video source that can be switched between it and the Challenger's video by an internal/external switch.
