Hi there, yes it's me again ;-)
Can anyone confirm if the attiny261/461/861's are usable with the Dragon Rider 500 (Ecrostech). The only 20-pin attiny they mention is the attiny2313 and that one probably has a different pin layout. The manual's last update seems to be from 2008 :-/
If I can't use the '861, it's little use to me...
