Sony PlayStation PSIO Switchboard Mod Kit


Mod Kit Includes:

  • 1 x PSIO Custom Switchboard


  • Allows use of both the internal optical drive and inserted PSIO cartridge
  • Perfect pad placement, conducive to neat wire runs
  • Updated online install guides
SKU: KIT-PS1-PSIOSB Categories: , ,


The PSIO switchboard allows the console to seamlessly run from either the internal optical drive or from an inserted PSIO cartridge.

My own designed switchboards have perfect pad placement for the four main PlayStation revisions; PU-7/8, PU-18, PU-20 and PU-22, making installs much simpler and neater.

Each kit uses high quality Panasonic resistors, AVX capacitors and a Nexperia IC. Each one is hand made using quality solder and flux to ensure reliable operation.

If you need an extra PSIO switchboard for your Cybdyn Systems PSIO, you can’t go wrong with one of these. Although it has been superseded by my PSIO-XS mod kit.
