			==Maybe Delayed Release?==
			If the rumors were correct they may have "used up" spare 81-240 A boards in the Kaypro 2 and switched the K4 '84 over to the new universal boards (81-184). Likely either they ran out of old cases or floppies then had just enough 81-240 A boards to cover warranty or replacement needs.

			<blockquote>
			If you're wondering whether your Kaypro II is really 4, just wait. Kaypro Corp is changing things all around again. Only this time the Kaypro 4 and 10 will share the same processor board and the II will have a 4 board. OK? ...

			The Kaypro II will have the original Kaypro 4 board and ROM. In fact, the present Kaypro II and 4 systems have a simple monitor sign-on that says "Kaypro" rather than Kaypro II or Kaypro 4. That way they can use the exact same board and ROM. The only thing you have to do to this version of the Kaypro II to turn it into a 4 is change the drives to double sided 48 tpi units.<br>
			(Micro Cornucopia, Feb 1984)

			Both the Kaypro 2 and 4 received major updates as the New Year came in 1984. The three significant updates for the Kaypro 2:
			* The floppy drives were updated to half height drives, they were still Single Sided Double Density. This required an update to the design of the case for the smaller drives. The new drives were also direct drives and in general were much more reliable than the proceeding full height drives.
			* The mainboard was updated to the universal board that would be shared among the new CPM machines for the rest of Kaypro’s production. This board usually was only populated with the circuitry required for that particular model. It appears that a Kaypro 4 or 10 board sometimes was used, likely when they didn’t have the correct board on hand.
			* The screen graphics from the Kaypro 10 became a part of the Kaypro 2. This is implemented as an additional chip on the main board.

			All of these updates made the Kaypro 2 become more like the earlier Kaypro 10 just without the hard drive.
