I recently dug out my Atari stuff out of storage to see if any of it still worked. I have a 400, and an 800 with a 810 Happy drive and a Percom drive. I had no joysticks. The 800 worked but the space bar did not make contact so I found the connections and soldered two wires to them as a sub. The Percom does not work and the Happy seems to be fussy. Some of my power suppliers also were not working. So I bought power suppliers, an XL, two 1050's and four joysticks. Have been testing most of my games to see if they work and have found a number that have gone bad. One of them is Galahad which is a shame as I really enjoyed the game. I did manage to finish it and got to the shrine. I assumed that was the end and never went any further. Loved the humor that you need to kill the rabbit with the Holy Hand Grenade. The other game that I loved but does not seem to work is "Seven Cities of Gold".
