			The Kaypro 2000 had two notable changes during its lifetime. Initially in the spring of 1985 it came with 256K of RAM with upgrade options of 512K and 768K. If configured with 768K then the upper 128K could be used as a RamDisk since the operating system was limited to the lower 640K. The start-up RAM check only tests the lower 640K and doesn't report the entire memory of the 768K version. In the summer of 1986 the base configuration was changed to include 768K of RAM.

	"Kaypro even has an optional dual input charger for less than $50 that operates from either 1 15v AC or 12v DC. This adapter replaces the adapter/recharger that came with your Kaypro 2000 and plugs into a standard 1 15v AC wall plug or the cigarette lighter in your car. If you happen to have a car with a 6- volt electrical system you don't need to buy the dual input charger.
