Magnavox Odyssey 2
Operating Systems (Intel 8048)
Odyssey BIOS
The BIOS reads the keyboard and joystick, displays character graphics and can even manage a simple clock.
Surely not an OS, but can mess around a bit with the system which is cool.

Version & Revision Guide
For general information, see the Game Console Revisions Overview.
Versions
There are two versions of this console, arranged chronologically.
“Odyssey 2 (detachable controllers)” (1978-????)
Both controllers are connected to ports at the rear, enabling removal at any time. Furthermore, the video out plug is restricted to only the OEM RF modulator.
“Odyssey 2 (hardwired controllers)” (????-1984)
RECOMMENDED OVERALL
The controllers have been changed to a hardwire, although they can be easily removed from the motherboard, as they are not soldered. Alongside this, the video out plug is now compatible with other RF modulators, such as the Atari 2600’s modulator.
There are no revisions within either version. BEST RELIABILITY and LOWEST PRICE couldn’t be assigned.
