Excerpt from the original announcement letter;

The IBM 8530, Personal System/2 Model 30 is a new general-purpose computer system which provides enhanced function beyond that established by the IBM PC and PC XT*, especially in display graphics, at lower prices to the customer. This system includes as standard, many newly integrated features such as a graphics adapter and parallel port. It also allows for the attachment of many existing PC option cards for further expansion. The Personal System/2 Model 30 is available in two versions, 8530-002 with two 3.5 inch (720KB) diskette drives, and 8530-021 with a 20 megabyte fixed disk and a single diskette drive. All models have 640KB RAM, standard.
