{{Stub}}<br />
==Introduction==<br />
What does it do?<br />
<br />
==Switches and indicators==<br />
* LED1 WG - write gate lit when the disk head writes.<br />
* LED2 RG - read gate, lit when the disk head reads.<br />
* LED3 FORM - write format, lit when the controller formats.<br />
* LED4 PAR - read parity, lit when the controller checks parity.<br />
* LED5 COMP - compare transfer, lit when the controller compares data after a read / write.<br />
* LED6 ECC - ECC operation, lit when the controller performs error-correction calculation.<br />
* switch for cable-type setting (pos. 7E): concerns B-cables only (B-cables are the cables going directly from the computer to the disk unit). The daisy-chain cable may be flat or round. Switch 7E consits of four switches, one for each disk unit (units 0 - 3). The switch must be OFF when the B-cable is round, and ON when the B-cable is flat.<br />
==Connectors==<br />
The A and B connectors are used for I/O, the C connector is used for the [[ND-100 Bus]].<br />

==I/O Devices on the card==<br />
