The UP2000 Motherboard uses onboard connectors to provide for:
n Alpha Slot B Modules
n Memory modules
n PCI and ISA modules
n I/O peripherals (keyboard, mouse, serial, parallel, and USB)
n SCSI devices
n IDE and floppy disk devices
n System power
n I/O connections (indicators and buttons)
These connectors and the system’s configuration jumper blocks are shown
in the following figure and table.

A pictorial view of the UP2000 disk I/O ports is shown in Figure 2-5. The
IDE and diskette port sockets are keyed with one or more notches.
The SCSI connectors are high density 68-pin female sockets. For certain
SCSI disk peripherals, a 50-pin to 68-pin adapter is required.
