I think it's also worth noting that the RT cab is actually a mid-sized cab: taller than a normal Net-City sit-down, and shorter than a normal Net-City Upright.
the touch-screen games were also this mid-height. But RT also has a unique color scheme with yellow plastics upper and a black base
Generally the major difference between a NAOMI Universal, a Net-City, and a New Net City is the monitor. (NAOMI Universal having a 31K only curved screen, Net City having a Tri-Sync Curved screen, and New Net City having a Tri-Sync Flat Screen). So if this has a different monitor than any of those it would be even more difficult to classify.
