Like the other Atari XEGS design but without the grey backing.
As stated for the other shirt, the Atari XEGS was released in 1987 to compete with the NES. It was fully compatible with the "Atari 8-bit computer" line of hardware, being able to run all of the games and hardware peripherals it could do. IT was comparable in power to the Atari 800XL, having 64kb of RAM but it also had Video out for more modern TVs.
The advantages of a massive library of great games and did give the 8-bit hardware a second wind but not enough to take down Nintendo.
