Some accessible controllers in the OneSwitch.org.uk pipe. Top two pictures are of my C-SID replacement. As well as accessibility switches, it allows for a team-controller (analogue) joypad to be used and optional (digital) MERU Moozi or Atari D9 standard joystick. It will also optionally come with a Titan One adapter with some custom profiles to make play easier.
The adapted impact will offer a very affordable way to get basic switch access to a PC. Both will work with the free One Switch Pulse / Gaming Redux system.
