Intellivision II

The Intellivision II is a video game console released by Mattel in 1983. The Intellivision II is an advanced version of Mattel's 1979 console, Intellivision. The Intellivision II featured several add-ons that the original model had as well as updated technical specifications.
The Intellivision II was initially designed to be inexpensive to make, however, during the production, it was designed with a flat membrane keyboard surface rather than the original raised bubble keypad. Due to this and games' reliance on the button's feel, some games were less playable on Intellivision II. 
Mattel suffered heavy loss with the Intellivision and the Intellivision II had little as well success. Mattel Electronics posted a $300 million loss. Early in 1984, the division was closed — the first high-profile victim of the crash.
