Memories...Like the Corners of My Mind

I ran into two computer geeks in a chatroom, and they think I can get back on S.L. if I just spend about $100 on more memory. It seems this old computer I got stuck w/ barely has enough memory to wipe it's own *harddrive. But in the real world fixing my truck took all my cash this month. Sooooo...who knows when I'll be able to buy more memory.
