Yes, the widebody cabs have a 19" monitor in them. The only other easily accessible Nintendo pcb that I'm pretty sure you could just swap in would be Popeye. Everything else is either different wiring (i.e. PC-10 or Vs) or has a vertical monitor (i.e. DK, DK3, DKJr, etc). That cab is a Widebody cab (aka original dedicated Mario Bros) which you can tell in those pics by a couple things. The faces on the marquee are not cut off (which they are on the smaller conversions) and the pipe on the right side of the bezel is not cut off (which it is on the smaller conversions). If the pic was a bit lighter you would notice that the speaker is right in the middle of the area below the control panel as opposed to a conversion cab which has it off on the left. As long as the monitor is working I would pick that up for $300 in a heartbeat. I got mine for $200 and have at least another $100 into it fixing it up. Oh, and be sure to go to
www.mikesarcade.com... and pick up the Mario Bros high score save/demo in freeplay kit. It'll run you right around $50 shipped but is well worth it (imo).
