I just finished getting the last of the stuff from the expo and while cleaning found a few things, so if any of this might be yours just send a PM.
1. The manuals for Millipede and Galaga88
2. Some boards (which I think might belong to Prok)
3. A long Phillips screwdriver
4. Some keys for games but we will contact you directly for those.
5. A 6 pack of beer (Bud Light)
