The IBM PC Junior was manufactured from 1983 to 1985. It used the 8088 processor, came with a CGA monitor and a single 5-1/4 inch floppy disk drive. The PC Jr. was not a big market success. The hardware interfaces were all non-standard, and it was not able to compete with other portables coming onto the market. It sold for about $1,300 when it was leased in October 1983.
