When IBM released its first personal computer, the 5150, 30 years ago, it was deliberately drab–black, gray, and low-key. Thatâ€™s because IBM intended the 5150 to be a serious machine for people doing serious work. So how better to celebrate this important anniversary than by using the 5150 for what it was meant to do? Working on a 5150 seems to be a tall task in today’s vastly accelerated computing world, however. Could a PC thatâ€™s as old as I am manage to email, surf the Web, produce documents, edit photos, and even tweet?
