PS/2 to USB A Adapter Male to Female Keyboard Adapter PS-2 Jack to USB A Plug for Mouse and Keyboard, Replacement PS/2 Keyboards Adapters, 4 PCS

I know ps2 is more or less gone but I run and build older computers and sue a KVM switch that uses emulation soevery once in awhile computers against the wall will braek one of these, this will work, good product

Nothing much to say here, these are simple adaptors that will take your compatible USB keyboard and mouse and allow you to use them on a PS/2 compatible computer. One thing of note that isn’t the fault of this product is that very new USB devices like mechanical keyboards or high DPI mice will most likely not work, you need something with a low power draw and very simple drivers. In my case Lenovo OEM peripherals worked great.

The USB to PS/2 works perfectly with my keyboard, however the one for the mouse, doesn't work. My mouse has a LED light at the bottom that tracks movement. The adapter does not provide any power to the mouse, hence the LED fails to light rendering the mouse inoperable. If you have the old style mouse with the roller ball instead of the LED, then you should be fine.

It helped me fix and older pc, it would not accept any input from USB keyboard used these and was able to get into the motherboard

These do not work. I tried woth 4 usb keyboards and 4 mouse on 6 different computers. Maybe im doing something wrong. I even ran a test signal through the usb and got zero response on the pins and that's woth all 4 adaptors that came in the package. I guess I wasted 6 dollars for nothing

No electronics in side to allow for use on a modern keyboard to connect it to a old PC -- just wires inside. Old usb key board did both usb and PS2 protocols, newer one only do HID. Will work for a old usb keyboard to a old PC.

good quality

Working as intended!
