Hi, this is in followup and clarification to my previous answer. I wrote that it was not possible to connect a green USB to PS2 adapter to a purple keyboard connector and was based on my own experience, but may wel be related specific manufacturers.. Some had proprietary plugs with slightly offset keys.Others had pinsockets blocked to prevent insertion into the "wrong" socket. Others did not have the internal wiring correspond to the required signal input pins which is different for mouse and keyboard. That's why there are 2 types - green and purple Will it work for some green plugs? Yes possible. But also possibly not on simple adapters. The more advanced ones have a chip in them to direct the signals to the right pins, be it mouse or keyboard. Peter E. On Tue, Jun 21, 2016 at 11:03 PM, Jesse A.
