Nice prototype unit thing on eBay. Seems to have a different BIOS? The auction is a bit unclear on details.
I'll try buy that thing - very expensive tho. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=180709001663 |

Exciting! =)
Would be interesting to see what's different in the BIOS. |

Did you try calling the guy? if he's giving his phone number for info then it's a good thing...
Since the guy sounds like he knows 'the scene' maybe a call from Bock will work in your favor? |

Nice! Those games look the same as the prototype Fantasy Zone and Ghost House that I sold you a few years back. | |

Yes. Those type of cartridges have been spotted a few times over the years, there seem to be more a few circulating. Maybe Sega gave those to early reviewers, or QA etc? and thus produced them in the hundreds. | |

I won the auction for $635, more news soon!
(luckily USD has become third-world money when it comes to change rate so its not so bad or at least that's what I'm making myself believe) |

It is a relatively late prototype unit, hardware seems to be final?
BIOS is functional, check for same header as retail unit, but has no boot up animation (only a static picture with no sound) and a bare instruction screen. |

Well, that's kind of a bummer. That Hang-On manual looks slightly different though. Any chance of getting a scan of it? | |

The five games are early prototype version with gridded manuals. All the dumps are different (tho we already have a dump for Ghost House). | |

Something special is hiding there... :) | |

Forgot there were games with it. So, they'll be dumped and analyzed soon? | |

There is a photo of an early production SMS here. This prototype has a number of minor differences from the production system:
2. The prototype has a small IC next to the CPU which is missing in the production version. 3. Finally, this system appears to have a prototype I/O controller. In place of the usual Sega 315-5216, there is a Fujitsu MB675xxx gate array. |
