The hell it was! I remember finding a low-res pinup on a shareware game disk and then examining the contents of every pirated or shareware disk I had. My parents asked me what I was doing, and I told them it was something terribly technical. I didn't find any more that day, but after that I looked at every disk I could get my hands on and did find naughty pictures from time to time. I even found a couple of programs that did nothing but display crude animations of people having sex. Some of the pictures were pretty good given the display limitations; I think they were scanned from magazines and then touched up by hand.

National Geographic and those shareware disks were my only sources of female nudity until I got older and managed to get my hands on R-rated movies. (Sheltered, yes, I know.)
