The Aspiring Lich has posted a fantastic Old School combat tracker. Laminated, it would be ideal for tracking in the old school. It even has a space on the bottom that is a grid. The grid is a great tool here for keeping track of where everything in the combat is, sans the miniatures. Check it out. I'll be using it in an upcoming session, and likely for both games that I will be running at Michicon this year as well.
