System Interface PCB
The System Interface PCB resides in ISA bus slot 2 of the Host Pentium CPU motherboard. As its name implies, the
System Interface PCB helps the Host Pentium Processor communicate with other system devices. Main features of
the System Interface PCB include:
• An Option PROM that configures the Host Pentium Processor’s BIOS for operation in the Workstation
• An ARCNet Controller and Interlock that enable the Host Pentium Processor to communicate with other intelligent
PCBs in the Workstation and in the image generator
• Data bus buffers that develop rewind, fast forward, play, pause, and record signals for the optional video cassette
recorder (VCR).
• Serial communication chips that enable the Host Pentium Processor to communicate with the modem, monitors
(for setup and automatic contrast/brightness control), Control Panel PCB, and Touch Screen assembly
SCSI Controller PCB
The SCSI Controller PCB located in PCI Bus 0 slot 7 enables the Host Pentium Processor to communicate with
several daisy-chained peripherals, including a removable media hard disk drive, CDROM drive, and magneto-optical
drive. The principal advantage of using SCSI technology is that one interface can control up to seven devices.
When the Workstation is equipped with an optional Cine Disk subsystem, the SCSI controller PCB connects to the PCI
Bus on the Cine Bridge PCB.
Ethernet (DICOM) Interface PCB
The optional 32-bit Ethernet adapter PCB resides in PCI Bus 0 slot 8. The PCB allows the Workstation to transmit
images over a local DICOM network. The card can communicate at up to 132 Mb/s with the Pentium PCI
motherboard, and at 100 Mb/s over the network.
