I was curious of what all chessboard systems are out there, but didn't know what site would have info similar to Rik's Handheld museum site.
Seeing how hap was doing heavy amounts of continual chessboard emulation for about past twenty months, I was curious myself (I peeked over at Bannister's shoutbox discussion ;-) ) But I was curious myself since I didn't know exactly which site would have a fair amount of info regarding chessboard systems. So here is one site for those that may be curious of what exists and what is yet to be emulated.
