SCSI Connection
The built-in SE SCSI port is implemented using an NCR710 macrocell
inside the I/O ASIC chip. This 8-bit single-ended implementation is compat-
ible with the current Series 700 products and supports 5 MB/sec data trans-
fer rates.
The SCSI bus is terminated to 3.3 volts through 127 Ohms on the system
board. If the board computer is used in a VMEbus chassis having internal
mass storage devices, those devices must have their terminators removed. If
an external disk drive is used, an active terminator must be used on the last
drive's uncabled connector.
Figure 4-10 shows the SCSI connector.
