SIO-X is an elegant PSIO switchboard designed by Voultar to make switchboard installs simpler and neater. It comes with the addition of an onboard modchip, Quick Solder Board design, and a number of other improvements over the standard PSIO switchboard.

What is SIO-XS?

SIO-X is one of the few mod kits designed by someone else that I wish I had designed. I kicked myself that I did not see this design opportunity. I think it is a great design, but for my own uses I prefer a separate modchip and switchboard. For this reason I decided to design the SIO-XS. SIO-XS simplifies Voultar’s design further by omitting the modchip and changing the layout a little. SIO-XS was designed from the ground up but is based entirely on Voultar’s work and SIO-X. So all credit to Voultar.

Why is it called SIO-XS?

SIO-XS for eXtra Small. SIO-XS for Sans, in that it is sans-modchip. SIO-XS in that it removes the ‘excess’ so it is just a PSIO switchboard.

SIO-XS is what I would have designed in an alternative universe if Voultar hadn’t designed it first, I would have probably called it something utilitarian like the PSIO QSB Switchboard. Yes, that’s a terrible name.
