Winter: For Winter 1990, we had another cover featuring a computer, this one room-sized with three people standing on the keyboard.
The first character is completely unarmed, the second is threatening the first with a club, and the third is threatening the second with a gun.
Meanwhile, the third character has a tank and an airplane dropping bombs in his immediate vicinity. This represented the growing danger within the hacker world, as one entity seemed to always have a bigger one behind it that was really calling the shots. Of course, this also paralleled with what was going on in the world with the calls for war in the Middle East.
Interestingly, and for reasons unknown, the entire image appears to be taped onto a blue wall.
The mini-cover is also a bit mysterious, with part of a map of Cuba appearing, along with Arabic writing that translated to "In the name of God, the Most Gracious, the Most Merciful," and a 43-digit long, seemingly random, sequence (4197169399375105820974944592307816406286208), which was actually 43 digits of Pi (starting with the 36th, running through the 78th:
To one of the many agencies monitoring us, it might have seemed like a code of some sort.
There were no search engines back then to quickly look this sort of thing up, so unless they actually tried to calculate Pi or had a listing lying around, they most likely would have wasted a lot of time trying to figure this out.
