Thanks Stefan / Colin for the detailed recap. I have the EDDAC model I built from Edwin's design. Wasted far too much time listening to MODs after that was built!

It really doesn't seem that long since I remember it being released. That makes my SAM (and me!) feel very old! The 20th Anniversary of the little blue (in my case) legged friend next year then.
