When Digital Research founder Gary Kildall examined PC DOS and found that it duplicated CP / M's programming interface, he wanted to sue IBM, which at the time claimed that PC DOS was its own product.

When IBM implemented the parallel interface on the IBM PC, they used the DB25F connector at the PC-end of the interface, creating the now familiar parallel cable with a DB25M at one end and a 36 pin micro ribbon connector at the other.
