3 models exist:

- 7-230: darkblue case, toy-ish looks
|
||||
- 7-231: gray case, hardware is the same
|

- 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.
