Upgrade paths

RAM

20 MB via NEC's proprietary memory expansion cards · Expansion used NEC-specific memory cards rather than industry-standard SO-DIMMs, so period upgrades depended on sourcing NEC's own modules.

MODERATE

display

Detachable screen housing swappable between monochrome DSTN, color TFT, and touchscreen variants · A distinctive feature of the line: the display module unclipped from the base and could be exchanged or reversed into a slate/tablet orientation.

EASY

other

Optional docking station adding two ISA expansion slots · Standard desktop-replacement docking accessory of the era, sold separately.
