Fascinating stuff. I wish I was older and active in the community at that time. I was but a wee lad and didn't really have the social experience that seemed to come with the Atari computer scene. I just learned and acquired games from various family members who also had Ataris.
Though I did go to computer shows and get disks from the MACE booth (Michigan Atari Computer Enthusiasts), who were sympathetic to my plight about being too little to have money to buy games, and they were amused that such a little kid was an Atari fan, so they would give me free shareware disks from time to time.
I was always fascinated by "cracking groups" from the moment I learned what they were, and would begin to follow who was cracking what, even though I didn't know anybody or anything about it. I would think, oh yeah, this game came from Captain Wizard, he also cracked my Spy Vs. Spy II game, etc. Glenn was always particularly enigmatic because I just couldn't fathom the concept of a guy converting games to a new system, though it seems a lot more reasonable now.
