Hey guys! Sante great to see ya post, hopefully you got the NW Dvd I shipped you?
Anyways......I can tell you what I know......exact numbers who knows??? There was NO such thing as a "dedicated original" Super-Punch Out machine. They were all built as Punch-Out and a year later Nintendo released a Super Punch-Out kit for operators that wanted to upgrade their machines. As far as I know, the kit came with the roms to swap on the pcb, new (pull up) joystick, and "Super" side decal.
I have spoke to several operators that were BIG on the scene in the 80's. Most of them have told me when Nintendo released Super that the original Punch-Out was still bringing in buckets full of quarters so there was NO real need to upgrade a machine that was making them good coin to begin with. As a result there were NOT a lot of Super Punch out games that made the conversion. Punch out seems to be a dime a dozen, still fairly easy to find. Super-NOT so much.
Yet.....all it takes to make an original into a SPO, providing you get around the security chip, is the rom swap,color proms, and joystick.
So.....if you ever decide you want just original Punch-Out, I would be willing to trade you a good working regular Punch-Out PCB + some $$$$$ for a working Super PCB. Been looking for a Super board for a while!!
Enjoy it!!
