This strange hybrid computer came in two parts: a videogame console and a computer. The game system, called the APF MP-1000, was released in 1978. It had two controlers, each with a joystick and a numeric keypad. It came with a built-in game called "Rocket Patrol".
The computer console, the "Imagination Machine" was sold as an add-on for the MP-1000. You could also buy both at the same time (most people did). The computer has a 53-key standard typewriter keyboard, a built-in stereo cassette deck (1500 baud), a built-in sound-speaker and an internal operating system and BASIC language interpreter. The APF BASIC, delivered on cartridge, was quite poor. You had to use a lot of POKEs and CALLs to play with graphics. For example, to clear the screen, the command was CALL 17046.
The video game system nestled on top of the keyboard module. This computer add-on concept would later be used by several game system manufacturers like Coleco with their Colecovision game system connected to the Adam Computer, or Intellivision and their ECS module (and keyboard component).

I learned BASIC on the IM-1 in the 7th grade. Great memories. I used to program up in the spare bedroom with a b/w TV that my folks could spare. When I'd finished a significant bit of programming, I would lug the big thing downstair to view on the big family TV to check the colors I'd programmed!
