Based on the Data East arcade game
Program/Graphics/Sound Effects/Music: Joe Jacobs and Dennis Clark

One day, Mattel Electronics was contacted by a couple of guys from New Jersey, Joe Jacobs and Dennis Clark, with startling information: they had hooked up a PlayCable unit to a personal computer and made their own Intellivision development system. They demonstrated that they had figured out how to program Intellivision games quite well, and they wanted to offer their services to Mattel before going to some other company. Ah, blackmail is such an ugly word...
To keep them away from the competition, Mattel contracted with them to program the Intellivision version of the arcade game Bump 'N' Jump. They, under the name Technology Associates, were paid $24,000 for the conversion.
David Warhol (Mind Strike) served as liaison, giving technical assistance as needed. Except for the title screen graphics by Daisy Nguyen, all the work was done in New Jersey, in one of the programmers' basements; they weren't invited to Mattel headquarters.
An M Network Atari 2600 version was also released. An Aquarius version was announced, but not released.
