JP8 CPU BOARD - 4 x Memory

Jupiter-8 CPU Board (Replacement / Upgrade)

This is a fully redesigned and enhanced CPU board for the Roland Jupiter-8 CPU Board, developed as a reliable drop-in replacement for aging and failure-prone originals.

The board is built using modern low-power CMOS and LS logic, significantly reducing power consumption and heat compared to the original design.

A major improvement is the integration of non-volatile FRAM memory, eliminating the need for a backup battery entirely. No more leaking batteries, no data loss, and no maintenance concerns — your patches are permanently retained.
