Single–Ended SCSI–2
The built–in SCSI–2 port is implemented using an NCR710 macrocell inside the I/O ASIC chip. This
8–bit single–ended implementation is synchronous and compatible with the current 700 series products
and supports 5 MB/sec data transfer rates.
The SCSI bus is terminated to 3.3 volts through 127k on the CPU board. If an external disk drive is
used, an active terminator must be used on the drive at the end of the cable.
Fast, Wide Differential SCSI–3
Fast, wide SCSI is an extension to the existing 8–bit, single–ended SCSI. "Fast differential" indicates
that signals on the SCSI bus are differentially driven and terminated , and capable of a 10 MHz clock rate.
"Wide" indicates that there are 16 data bits on the SCSI bus.
The fast, wide SCSI bus is specified at a peak synchronous transfer rate of 20 MB/sec. The architecture of
the fast, wide SCSI port on the J Class workstation has been designed to allow a 20 MB/sec sustained
transfer rate for long data streams.
Power Cord Connector
Plug the workstation's power cord into the power cord connector to provide ac power to the system.
