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. 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.
