About the I/O Connectors
You can connect external devices to the input/output (I/O) connectors. The computer's basic input/output system
(BIOS) detects the presence of external devices when you boot (start) or reboot your computer.

NOTES: Some external devices require you to load software called device drivers into system memory
before the devices will work. These device drivers help your computer recognize the external device and
direct its operation. Instructions for installing this software are usually included in the upgrade kits.
The C/Port Advanced Port Replicator (APR) has the same I/O connectors as your computer. In addition,
the C/Port APR has a second Personal System/2 (PS/2) connector, a second Universal Serial Bus (USB)
connector, and an Ethernet network connector.
The C/Dock Expansion Station has the same I/O connectors as your computer. In addition, the C/Dock
Expansion Station has a second PS/2 connector, a second USB connector, an Ethernet network
connector, and a small computer system interface (SCSI) connector.
Parallel Connector
Use the 25-hole parallel connector to attach a parallel device to the computer. The parallel connector is used
primarily for printers. You can also connect the diskette drive to the parallel connector.
The parallel port sends and receives data in parallel format, where eight data bits (one byte) are sent
