The monitor that belongs in a sega cocktail table (frogger, zaxxon) is a Nanao MC-2000-s 20" monitor it has like a metal wire frame and fits the cocktail snugly, froggers came out with 2 size monitors the 13" is the older table, the chassis you are showing doesn't go in that table it was replaced at one time as the nanao are not an easy monitor to fix but have great pictures
