The if 486 VX series was positioned to be a more cost effective version of the if 486 VX 520 series with added features such as LAN connectivity and a VGA monitor. There were four models in three configurations: the if 486 VX 510E, the if 486 VX 510S, the if 486 VX 530, and the if 486 VX 550. The if 486 VX series used monitors with an AX-VGA/H architecture, which permitted the use of overseas VGA applications while maintaining backward compatibility with previous applications.
In September 1992, Oki Electric announced two additions — the if 486 VX 530D and the if 486 VX 550D — with more powerful (66 MHz) CPUs.
