Coming in at $179.95 at launch, it sold at an acceptable rate throughout it's lifespan, but was unable to crush the monster that was the Game Boy. When it comes to specifications, the Atari Lynx is a relatively capable system, containing two 6502 variant CPUs that run on a 16-but bus, alongside 64K RAM, 4 sound channels, and the obvious 12-bit color text/html 2022-04-13T23:14:19+00:00 Anonymous (anonymous@undisclosed.example.com) https://io55.net/wiki/eop/video_game_consoles-portable/4th_generation/hartung_game_master?rev=1649891659&do=diff Hartung Game Master Released in 1990 primarily across Europe, the Game Master was one of those miserable attempts to beat the Game Boy in market success. Online specification information is poor, but it is known to have a 64×64 monochrome screen with the NEC upd7810 CPU. Since it was so weak, it probably had alright battery life and longevity, but the quality of it's games did it no favors. text/html 2022-01-13T22:46:23+00:00 Anonymous (anonymous@undisclosed.example.com) https://io55.net/wiki/eop/video_game_consoles-portable/4th_generation/nec_turboexpress?rev=1642113983&do=diff NEC TurboExpress Releasing in December 1990 for both JP and the USA, the TurboExpress is quite simply a portable conversion of NEC's somewhat successful TurboGrafx-16 home console.

For this console, see Nintendo Game Boy Color. Releasing in September 1989 for the USA, the Game Boy was a wildly successful system for years. Containing only 64 KiB of RAM, a 160×144 monochrome screen, and 2-bit color, it's primary genius was in it's long battery life and easily digested games. Both of these features allowed the Game Boy to overcome it's weak capability.
