Ooooh, this is nice. I may have to see about getting one of these when/if my Atari 400 gives up the ghost. I still have a few games I like playing on it. :)
I keep hoping for one of the open source clones to become playable, but they never seem to get that far. Someday I'll have to contribute myself I guess.
The C64 tape version of Zaxxon was the "good one", right? I loved that game.
Believe it or not, I never played M.U.L.E. I know everything about the creator and the game, and why it's a landmark, but I never encountered it back in the day!
