no, i don't have one, even though it was on my wishlist since i got knowledge of its existence (1992, a father of a friend of mine went in japan and brought back some computer magazines, along those one called 'technopolis' that was showing parodius for x68000); i tried the human OS (the x68k operating system) in an emulator and looks like is just at the level of the old 64 GEOS; in my opinion AROS have also the chance to bring a more modern computing experience (preemptive multitasking and other amiga features) to other 68k systems and making them more usable even for retrocomputing purposes...

what we need for a x68k port though is for sure kanji/kana support (for video, i seen in wikipedia that is the same kind of card used by many arcade games, and some models used SCSI disks)
