Hi my friends,

Just to present my ZX Spectrum +2B mods and a good peripheral that I bought time ago in one Spanish forum ... Multisystem FDD Interface for ZX +2A/+2B & CPC 464

First the ZX +2B mods..... Just the Reset & Pause switches

For the Pause switch the first step is to locate the correct points at the PCB

The two switches connected

The interface connected & working. This small and great interface can emulate the RDY signal and works great with 720Kb formatted FDDs
