Prophet 10 “Memory Liberator” F-RAM Upgrade (replace all 4 RAMs with just one chip and lose the battery!)




The Sequential Circuits Prophet 10 normally uses RAM chips to hold program memory, which are out of production and increasingly difficult to find. In addition, a problem with just one of them can cause serious functional issues with the synth, and the bad chip can be difficult to narrow down because there are several of them!

Our Memory Liberator board is a battery eliminator module that replaces ALL FOUR of the original RAMs with the single modern ferroelectric RAM chip housed on our board.

This retrofit does require soldering of 3 wires to install.
