"The Kaypro Corporation, a Solana Beach, Calif., computer manufacturer, announced that it had reduced the price of its Kaypro 4 personal portable computer by $200, to $1,795. Kaypro said the price reduction, which does not affect the Kaypro 10 model, is a result of supplier cost reductions in both disk drives and video display screens, coupled with increasing volume orders. The Kaypro 4, which uses double-density disks, features 392K of formatted storage per disk for a total of 784K for the unit's two disk drives."
