@Holoptics, You simply need to declare the 88 inputs in your top level file and then the pin locations in a constraint file (.acf is usually the easiest as you can use the bank/pin numbers)
@Jon, a lot of 5V devices will happily accept 3.3V as a 1. If you need to level shift it there are numerous ways to do so. For example, https://www.sparkfun.com/products/12009
@jdeschamps, The dual voltage pins should just work. It's possible you have a bad board. The chip that does the dual-voltage selection has some tiny pins on it and it is possible it wasn't soldered properly. You can contact us at support@alchitry.com to arrange a repair.
