Specifications
The keyboard connects to the KBD (keyboard) connector on the rear of the
system unit. The keyboard also contains the system speaker.
When the IBM 5080 Graphics System is connected to the IBM 6150 System
Unit, the keyboard attaches to the Peripheral Connection Assembly (PCA)
of the IDM 5085 Graphics Processor. The PCA is installed in the base of
the IDM 5081 Display. The keyboard/tablet attachment cable connects the
PCA on the IBM 5085 to the M (mouse) and KBD (keyboard) connectors
on the IDM 6150 System Unit.
Whenthe IDM 5085 is attached, the IBM 5085 Keyboard is used. The IBM
5085 must be On and operational before the keyboard can be switched for
use by the IDM 6150 (Alt-Sw Keybd).
The Keyboard is a single field-replaceable unit and cannot be serviced in the
field.
