[GENERAL CYBERPUNK] I'm a regular hacker in a regular hi-tech-low-life world. I'm about to be sent back to a parallel world's 1990s, naked. How can I make lots of money?

Learning the basics about the period goes without saying, but memorizing winning lottery numbers is useless: I have no idea what exactly would be different in that world. I think I should use my knowledge of both tech and social engineering. Some of the problems science struggled with are already solved, and solutions might be easy enough to reproduce by memory, since I will have no actual gadgets or code. The same goes for scams — some things only work once, and haven't been done yet in that age. On the other hand, the tech will be really archaic and unfamiliar, some of the stuff I know just can't be implemented yet. Last thing: I don't want to try and replace Gates, Wozniak, Torvalds or another *legal* billionaire — I prefer to stay hidden. So how do I make a shitload of bucks?

So, you went FROM a time it is doable to become rich trough hacking, to a time when hacking is mostly a hobby that are Limited to a few machines, since there are no global network to take advantage of.

Why not just save a step in the process of whitewashing money, and become a legal millionare?  
If management isn't for you, just start working for one of those. People will surely have work for a hotshot programmer with revolutionary methods.
