I'm not for sure what everyone is looking at....but.......
The first three MCR games (Kick/Kickman, Solar Fox, and Tron) use the same transformer assembly. Everything is mounted on a piece of wook at the bottom of the cabinet. There is no metal "suitcase" containment, and the input AC voltages are hardwired.....making removal "unfun".
The fourth MCR game (Satan's Hollow) is when the "suitcase" made it's appearence. There is no hardwiring on the suitcase, making removal and repairs much easier. Beyond this......THEY ARE IDENTICAL, in function and electronically.
So, are they the same?.....connectors---NO, everything else(output, voltage)---Yes. Could one be used in place of the other?....with some connector mods---yes.
