6500PLUS Network Storage Option Card
Introduction
	The 6500PLUS network storage option (NSO) card expands basic node memory for
	support of large packet sizes.
NSO Card
	The NSO card has a 3.5-inch high-density floppy disk drive with a storage capacity
Description	of 1.4 Mbytes (MS-DOS–formatted disks). The disk drive is used to download new
	and optional software to the node. The card contains 1 Mbyte of DRAM, which can
	be increased in 2-Mbyte increments to 5 Mbytes by inserting SIMMs.

The MEM lights on the front panel indicate the amount of NSO RAM used by the system. A node with a lot of memory in the processor card may not use all the memory in the NSO card. In this case, only some of the lights on the NSO card may come on.
