Microsoft went public in March of 1986 and at the low low price of $21.00, you could have bought stock in it if you were around at that time. If you weren’t, perhaps you should consider building a type of time travel device. There might even be a set of plans available on this very site. Should you succeed in building one, feel free to contact me. There’s an early 90’s haircut I would like to go back and avoid.
