SYSTEM OVERVIEW
KEYBOARD
There are two types of Keyboards that can be used with the AT&T
Personal Computer 6300. They are the Model 301 Keyboard
(Figure 2-25) and the Model 302 Keyboard (Figure 2-26). Both
Keyboards have two different positions that can be adjusted to suit
the operator; each Keyboard can be tilted 4 or 8 degrees. The
Keyboards have a permanently attached cable that connects to a
connector at the rear of the System Module. This shielded cable
has 5 wires:
+
12 V dc, 2 Grounds, and 2 bidirectional signal lines.
The cable is approximately 6-feet long and is coiled like that of a
telephone handset. The central (alphanumeric) part of the
Keyboard is standard. There are 10 function keys on the left of the
Model 301 Keyboard. The function keys on the 302 Keyboard are
located in a row on top of the Keyboard. Both Keyboards have
15 numeric keys on the right-hand side that have legend for their
numeric functions, cursor control, numeric calculations, and
display editing. Both Keyboards support the AT&T Mouse 6300.
