History of the Linux Kernel Archives (KernelTrap)
Peter Anvin has been involved with Linux since nearly the beginning. When Linus Torvalds purchased his first computer on which he began writing the Linux kernel, the state-of-the art PC with 4 megabytes of RAM and running at 33 megahertz was too expensive for him to buy outright. Therefore, he financed much of the nearly $3,500 price, planning to pay it off over three years. Within a year as the Linux kernel began to evolve and a community of users formed, Peter organized an online collection that raised $3,000 and paid it off."
