The Nanao MS9-29 was an arcade monitor manufactured by the NANAO Corporation (now known as Eizo Corporation)[1]. The MS9-29 proved to be a popular choice of Sega Europe being fitted to many genre defining machines like Daytona USA and House of the Dead. It was also known for its usage in Sega New Astro City and Taito Egret II cabinets.
The MS9-29 was a successor to the previous MS8-29 in almost every way, with improved safety (due to more components being on the secondary side instead of the primary side) and better colour adjustment with a dedicated Contrast pot. Sadly the MS9-29 in its default configuration suffers from a slightly softer picture than the MS8-29 in 24Khz mode, however a modification has been identified to restore the sharpness of the MS8 to the MS9[2].
Even to this day the MS9-29 proves to be a fan favourite.
