Hey guys, since everyone here seems to be an expert on SF I thought this would be a good place to ask. I'm a huge SF fan and am currently working on a new cabinet. I was curious about how far apart the two joysticks were? Also, how far, center to center were the buttons? Thanks so much guys!
Original "Street Fighter II: The World Warrior" machines were usually in Dynamo HS-1 or HS-2 "cut-corner" cabinets. These had 19" monitors. Since all SFII:WW machines were conversion kits, there is no such thing as "dedicated" ones, the closest thing being when an operator or distributor would buy a new empty cabinet from Dynamo and an SFII kit from Capcom and make a new complete SFII machine that way.
So for SFII:WW, the measurements you asked for would depend on where the operator happened to drill the holes. Sometimes this was influenced by existing holes that were already in the panel (new empty cabinets or new replacement control panels didn't have that problem of course), such as in the case of this SFII:WW CP:

Here, the "thrifty" operator (or whomever) obviously reused holes from an Ikari Warriors or Victory Road control panel. 1&2 player start buttons, both joysticks and two of each player's buttons are in the default Ikari locations. Of course, this resulted in a ridiculous layout. It is not too bad for player 1 (though the buttons are in an odd position relative to the joystick), but it might as well be unplayable for player 2, unless player 2 is a 10-year-old lefty.
The CP I got from D_Zoot has always been an SFII CP, and has the correct SFII layout. The joysticks are 13" apart center-to-center and the buttons are 1.5" apart center-to-center. The closest button to the joystick is 2.75" to the right of it, center-to-center.
Now keep in mind that this is for the 23 5/8" Dynamo CP which is found on the 19" monitor cabinets. The first true dedicated SFII machines were Champion Edition's in Dynamo HS-5 cabinets (25" monitor). These had wider control panels (25 3/4"). Here is a picture of one of these wider CP's from a dedicated SFII:CE machine:

On these wider cabinets, which were used for dedicated SFII:CE and SFII:HF machines, the measurements I stated for the narrower CP above are the same except for the distance between the joysticks, which are 13.5" apart, center-to-center.
