The seller sells many ODM motherboards,including Ringedge and Lindbergh boards.and he called me and send this to me today earlier. Anyone knows what's this?
It's some sort of ATX-like motherboard for sure, but I have yet to see a normal PC board with that many power connectors (or whatever all those molex-ish ones near the memory slots are), or with the two red slots in line with each other. The latter reminds me of connectors for a riser card, or very vaguely VLB on old PCs or Zorro + ISA slots for bridgeboards on big box Amigas, but this is obviously much newer than either. My guess would be that this is the motherboard to some PC-based arcade system, but I couldn't tell for sure, nor what system it might be.
Clearly not a PC motherboard, modern cpu socket and pci-e slots yet there is no ide or sata connectors. clearly a custom board for something else.
The only thing wrong with that motherboard - Socket 775, if I'm not mistaken - is the layout. It's built to be mounted in a custom-styled case alimented from the front/back/whatever, anyway, PSU was intended to be out of the mobo's case, or plug directly into it like an additional side-module (like the Mac G3 for example). Also... are there actually SATA/IDE/SCSI/whatever connectors on that board? Could it be that the red riser slot was used to house a custom ROM/Flash disk? It's likely that the unit shipped with Windows XP Embedded... can you take actual photos of the ports and of the chipset? Conclusions: As xdaniel said, it's definitely custom. It's not Win98 era, but much more XP-era, and it's not gonna fit in a pc case. It looks mint though. That may actually be a custom arcade PCB. Edit: pas7680, we noticed the same thing at the same time
well,I have no more photos,seems the guy who send this to me is at the factory and choosing what to get.So when I told him this may not a game board and he doesn't take this back..
