			Note the card from this computer is a later model with a higher speed processor which can be distinguished by the switch on the exterior plate.
			See the #338575 “Expansion Unit” CPU Card for an example of the early 4.77MHz card without a switch.

Kaypro PC #338575 "Expansion Unit"

	===Overview===		===Overview===
	This ~~unit~~ is ~~labeled as "Kaypro Expansion Unit"~~. I am still ~~trying to figure out if this is a standard KPC or what~~ the ~~"Expansion Unit" actually means and if~~ the ~~case front was not with originally with this machine~~.		Of the “Expansion Units” that I have seen in person and online they seem to be consistant in that they are based on the “Kaypro PC” (KPC). The case and CPU Cards are the same as their KPC cousins. Where they vary is that their memory is on a separate card rather than one the KPCs “Multicard”. This also means that the IO features are performed by a different card which usually has the video output functions on it. Also the floppy drive functions are performed by a separate card.

			This means that the IO functions are usually limited due to there being only a parallel port since the video port fills the other half of the card’s external plate.

			To me the name “Expansion Unit” is a poor name for the functionality of these machines. I am still looking for the reason why Kaypro named them the way that they did.

	~~===Technical Info===~~
	"Documentation for the Kaypro PC Expansion Unit is on the way from Kaypro Corp. The bank of five switch settings on the Expansion Unit's Processor Card works the same as on the Kaypro PC. Additionally, the bank of four switches on the Memory Card works the same as SW1 on the PC's Floppy Combo Board. In place of this, simply use the regular Kaypro PC switch settings."<br>
