Well, based on my endeavors with the 8bit underground, I am entering into a mode in which I am going to be in perpetual search for collections of disks for really any 8/16 bit system (atari, c64/128, apple2, TI, etc - just not PC and mac really) that potentially contains downloads from the underground scene back in the day - hacking/phreaking applications including stuff like box programs, bbs software and file areas, downloads from bbs's of (then) copywritten games that potentially have "cracked by" screens, etc.
If you weren't into warez and bbs'ing prior to 1993 or so you probably dont know what I'm talking about, but I figured I would put a feeler out here since I've discovered this forum and the associated blog.. this is a great place...
