Recel System III MPU clones are available

RS3CLN is an exact replica of the original Recel system III MPU which is used in several Recel pinballs from the 70’s. Dimensions, connections, timings are totally indistinguishable. To make it work in a Recel pinball, just disconnect the 3 connectors (PC, MA, MB) from the old MPU and unmount it from the metallic backbone (unscrew the plastic spacers and the power transistors). Then, mount the RS3CLN replacement board in the same way, with the spacers, and reconnect the 3 connectors., PC, MA, MB. That’s it.
