The CD32, an odd Amiga-based home console from the UK, has a little-known arcade variant created by the italian company CD Express. An ebay auction recently ended for one, and it’s made to fit into a JAMMA arcade cab. Check this french CD32 site for more info on the console (in english!). The variant plays all normal CD32 games, plus the arcade-specific titles released by CD Express. Thanks to GSW for the link.
