Hi Al---
This old thread has links to an eBay auction we discussed awhile back:
viewtopic.php?t=2597&lighter=dragonchessThe rules and specs for DragonChess appeared in Dragon100, and were also published with some additional info/details on the WotC downloads site; that file isn't there any longer, but you can download it from
http://www.geocities.com/Area51/Rampart/3956/dchess.txt (I also just submitted the file to Canonfire!, so it'll be up there soon as well).
