'Wonderland' IS the right title. It was developed by 'Magnetic Scrolls' and published by 'Virgin Mastertronic' in 1990. MobyGames has a few
screenshots of several box artworks. Hope that helps a bit. I haven't looked around on the web for that game. But it definately is abandonware.
EDIT:
Uhm *cough* *cough*... what did you look for at underdogs? :blink:
