PCMCIA cards, or one Type III PCMCIA card.

the system. The VersaBay II expansion slot allows the user to replace the standard diskette
drive with a number of different NEC options including a CD-ROM reader, a second bat-
tery pack, or an additional hard disk drive using the release latches on the bottom of the
unit.

dard QWERTY format. The keyboard provides 12 function keys and 8 cursor control keys,
with an Fn key for ROM-based key functions. The numeric keypad is embedded in the stan-
dard key layout.
NEC VersaGlide
The NEC VersaGlide is a built-in mechanism that functions as the system's mouse. It con-
trols the on-screen pointer (cursor). To use the VersaGlide, glide your finger across the
NEC VersaGlide pad, and the cursor follows. The buttons on either side of the NEC Ver-
saGlide allow the user to select or deselect menu items. Tap and double-tap are supported
on the VersaGlide pad.
The NEC VersaGlide is the system's default pointing device unless a PS/2 mouse is in-
stalled. If an external mouse is installed, then the NEC VersaGlide is deactivated. A serial
mouse is not supported.

tem memory up to a maximum of 40-MB. In addition, 256 KB of read-only memory
