Abstract:

The NOSC-developed UNIBUSUNIVAC compatible InputOutput Controller IOC is designed to provide any host computer supporting the Digital Equipment Corp. UNIBUS configuration with an InputOutput IO channel whose protocol, timing, and electrical interface specifications are compatible with standard NTDS FAST and Univac 1100 series IO channels. In addition, true differential IO operation is provided for use in systems where this is supported or where intercomputer grounding problems exist. The IOC can operate when connected to either a peripheral IO device such as a line printer or a card reader normal mode, or the IO channel of another computer intercomputer mode. The mode is software selectable. By using IOCs in multiple hosts, parallel intercomputer channels may be readily established between them. Unless specifically noted otherwise, the device connected to the IOC will be referred to as the IO subsystem regardless of the mode being used. The computer housing the IOC will be referred to as the host. Keywords Inputoutput signals.
