I've seen the Konix console at a computer fair in London at the time. It was sitting there at the show with a sign saying 'Not working at the moment'. We were all dying to try it out though.
I used to own the
which was available to buy for the C64 game Echolon.
You had to shout 'Fire', as the stick button was used for some other action.
Compatible with all VCS games too.
Great fun.
