Today I got this from ebay for 1€.
What the hell happened to that mainboard? |
|||
|
||||
Ooh, heat pipes! 
That thing up there must be what mod chips were like, back in the 70s or something...  |

that's this DC ver. 1 mobo. It's liquid cooled. I have never seen a Ver. 1 so I have no idea what all the red wires goto. If it's a mod chip all i gotta say is holy crap, that must have taken friggin' hours. | |||

My guess that could be a mainframe board for an very old arcade machine of some sort? just a guess

Thats a VERY interesting find! If you want to know what that is (since I havent a clue), try asking around @ DCFORUMS and DCHOMEBREW.
LOOKS like either a mod chip, or that the person attempted to modify a Dreamcast mainboard into a Devkit, or an Atomiswave machine. It is hard to tell from the photo though. |

That's the auction. Those chips on the red wires were taped on the top of the disk drive. So a small part of the metal plate that covers the mainboard was removed. It's from an electrics workshop... I don't know who had it before and added those wires and I don't know where the rest of that DC is. The only part I tested is the disk drive... I doesn't work. It just does not move... Maybe the laser is still OK. What should I do? I can hang it on the wall . . . 
EDIT: A new picture I don't know if it's interesting (I don't think so) but on the DC's chip there's written: MPR-21068 SEGA JAPAN 9847 D Strange mod chips: ATMEL ATF16V8B 15JC 9902 and 9935. There are 27 red wires |

||||
| Well, I'd be interested in it. | ||||

Well... Short Info first: It's an old '98 Mainboard. That's why it's got this special cooling system.
It's supposed to be Mutli-Norm, but I didn't test it... I only have got PAL stuff. In fact I didn't test it at all but I guess it should work. So... I'd be interested in a working disk drive... if you have too many of them...
Ah... I just don't know...
What would you say? |
|||
|
||||
| Sure, I'll swap you a GD-ROM drive for it, if you want. Would you include the heat sink cooling unit as well? | ||||

You're talking about those metal plates and pipes? They're are part of that thing, i guess
Of course you'd get the fan, too. |
|||
|
||||
| Ok, sure. I'll swap you. You wanted a GD-ROM, right? Anything else, or is that it? | ||||

I'm fine with it, as long as it's still runnig  |
|||

the heatpipes were in most of the jap versions of the dc instead of the heatsink like thing on the top plate of the metal dc mobo cover. i dunno why those red wires are there though. *scratches head in confusion* | |||
