Initially, the organization had 17 recognized chapters in Metro Manila. The PCS-JPG was the only national student organization that catered to computer enthusiasts from different educational institutions around that time.

On July 1990, PCS-JPG changed its name to Junior Philippine Computer Society (JPCS), a committee under the arms of the PCS. On 1990, the first national computer convention for the youth, "Explore IT '90", was launched. The second computer convention was also a success and helped promote JPCS to other schools and sectors of Philippine Society.
