When I first heard there was a dance machine available I thought "Ugh, what am I going to do with a dance machine?", then I remembered my early days of games development when I was roped into programming a prototype dance game for the 'Gizmondo' failed handheld, which thankfully never occurred, although I really did get into it at the time and had a good play with Stepmania.
Learning that it's quite a rare one has triggered the preserver in me, so I'll be fixing it up and making notes on its internal operation along the way. Hopefully it will be available publicly to play either in my own arcade or somewhere where it will be appreciated.
