Anyone know a good resource for an older ISA Half-Size Motherboard? I may need one if i can't get the one on my '00 EZ Trak to come online. Replaced RTC and now I've got nothing. Even if I get this one back up and going, I figured it would be a good idea to have a backup. This board is in a CIB and the part number is SBC-8251. This board must have been a replacement at some point for this machine in its life because I found a manual for a Rocky 518HV Ver. 4.X Pentium Half-Sized Single Board Computer with other documents in the cabinet. Found a few on good'ole Ebay but most are China sellers. Best I can determine, these boards are ISA 586DX series.
