External VGA Capability
The NEC Versa 2400 Series notebooks provide a 15-pin female D-type external VGA con-
nector that can be connected to an external video graphics adapter (VGA) type monitor.
Another feature of the notebook computer is the ability to auto-sense the display output to
both LCD and the external CRT monitor. The notebook provides external resolution of
1024x768 by 256 colors for the NEC Versa 2400 series with 1MB video memory. The
NEC Versa 2400 Series can also provide simultaneous display at 800x600 at 256 colors
with the standard VGA DSTN LCD.
KEYBOARD SUBSYSTEM
The Keyboard Subsystem of the notebook is implemented on the I/O Board and Keyboard
Assembly using the Motorola G10 LapKat keyboard controller chip.
The NEC Versa 2400 Series keyboard is an 87/88-key, IBM enhanced-type keyboard with
standard characters and function keys plus 12 programmable function keys and the Special
Function (Fn) key. The notebook also provides an external PS/2 port for supporting an ex-
