CHARACTERISTICS

This Personal Com put er line is highly mod ular. The diff erent mo dels of this prod uct line, in fact ,
are the result of the combinat ion of two differ ent board versions (ENTRY and ENHANCED),
different CPUs (i486 SX, i486 SX2, i486DX2 and Intel DX4) and two diff er ent cases (T IN BO X and
SLIM TIN BOX). The mode ls of this produc t line are listed in the following table.
