- 7-232: this one is completely different hw --> driver k28m2.cpp - 7-232: this one is on completely different hardware*
*: Considering the different look and feel and the 4 year difference, k28o is not
a MAME clone set of k28. It's more like a predecessor instead of an older revision.
See k28.cpp for the newer version.
