I'm the slot card admin for the ChipGuide website and publish the Slot Card Guide. I'd be interested in getting scans (front and back) for any slot cards we don't yet have listed in the guides so that we can be more complete. If you have any time to check what you have vs what we have listed you can send scans directly to me or submit them to the ChipGuide.com website and I'll get them listed in both guides. And if you have any duplicates, I'd be extremely interested in looking through any of the extra foreign cards you might have.
