This adapter will allow you to use standard PS2 Keyboard and Mice with SGI Indigo computers. This single interface supports both a mouse and keyboard simultaneously. This sale includes the required 6 pin din male cable to connect directly to the single keyboard/mouse input on the rear of the Indigo.
There is a modification required for this to work correctly on R3000 Indigo workstations. The author has provided this mod . If you have an R3K Indigo and would like me to perform this update prior to shipping, please send me a message and I'll happily apply the mod.This adapter works great from the prom command line and within the IRIX desktop. I will include a 3D printed case in whatever color I have loaded on my 3D printer, currently shipping purple.
