	"Like the Kaypro II, which competes directly against Osborne computers, the new Kaypro 4 contains 64,000 bytes, or characters, of internal memory and is powered by an 8-bit microprocessor. But the new model contains twice the memory capacity in its disk drives, which transfer information for permanent storage on floppy disks. The new drives have a maximum capacity of about 800,000 characters. ... The new machine will sell for $1,995, the company said."<br>		"Like the Kaypro II, which competes directly against Osborne computers, the new Kaypro 4 contains 64,000 bytes, or characters, of internal memory and is powered by an 8-bit microprocessor.

			<blockquote>
			Since this review was completed, Non-Linear Systems has revamped its product line for 1983 with two new system configurations (the Kaypro 4 and Kaypro 10)...

			The Kaypro 4 is essentially an upgrade of the earlier model. Like its forebear, the Kaypro II, the Kaypro 4 is a portable, CP/M-based system with 64K bytes of RAM and two double-density floppy disk drives. The three major differences are that (1) it has doublesided disk drives (each offers 380K bytes of storage), (2) it is packaged in a dark gray case, and (3) it costs $1995. A minor, if inexplicable difference, is in the product name. NLS has shifted from using roman numerals (e.g., II) to arable numerals (e.g., 4)— a change not without historic precedent.

	"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."<br>		"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.
