I bought a bunch of these last time they were $15, to resell at the flea.
Anyways, I tried out the PS/2 model, and I couldn't get it to work. I was using an IBM M-13 trackpoint II PS/2 keyboard (which also uses the mouse connector).
I couldn't get the PCs to recognize that there was a keyboard plugged in. Has anyone else had this problem with these units? Or did I just get a defective one?
