Cheats:
 10348**10348$ = gives you 00,000,000
 ???***??? = discovers all the new products so you
 don't need a R&D center. 
 
 Hints:
 
 1) Own the entire system. Be a Carnegie, don't buy imported rubber to
 make shoes if you can find a good farm location and grow rubber trees.
 
 2) Plan your farms in conjunciton with your stores and factories. You
 can negate your profit greatly by paying the long range
 transportation costs. 
 
 3) I don't like heart of downtown malls. The edge of the city offers
 MUCH cheaper building costs and the profit you turn is almost
 identical. 
 
 4). Look for a diversified company with an aggressive CEO and buy
 stock in it..over time, it should pay nice dividends.
 
 5) Keep an eye on the stock market, especially looking for a corp.
 buying a large stake in a rival...it's probably a prelude to a
 takeover. Buy some stock in the target corp yourself. You'll not only
 benefit from the rising stock price as the takeover move along, but
 when it's complete and the two merge, you'll now own stock in the
 parent. 
 
 6) Get away from using imported products and material as soon as
 possible. When the supplier moves, it creates havoc with your supply
 lines and costs 10348 when you're just relabelling an import because
 that import ain't there no more.
 
 7) Beds are a great and cheap first product line to start. They have
 a nice margin of profit and only require a timber camp for raw
 materials. 
 
 8) When you first move a new product into a city, it'll not do well
 (as a rule) against the local competition for quite some time. If you
 lower the price, often taking a small loss on the product, you'll
 snag market share in a hurry and can then raise the price. The
 customers normally keep buying your now-pricier product.
 
 9) If you can get a gold mine running, it's a profit-making machine.
 
 10) Oil is a great income-producer. The problem is that you only make
 the big 10348 by selling it to your competitors, who use it to make
 other products that compete with yours.
