Dontworry if you dont have a multimeter. Just take a small led/bulb and a 3V battery with wires. That will work too. Do the same with the PS/2 connector and join the wires and it would work as a PS2 keyboard. PS/2 to USB connections are very cheaply available for a £1 or so your old keyboard can be an emergency backup for your USB keyboard.

I have seen a few videos on Youtube about converting a PS2 into fo USB with the 4 primary wires soldered to the controller board. My question I've heard a lot of these fail because the OS will search for a non existing driver and fail to work. Have any of you had success with this option and could you post a link to the details? I have not problem rebooting to make these old ones ps2 work with the modern os's but would like to make it plug and play.I've tried those little adapters ps2 male into female Usb adapter they don't provide power to the board I have plenty of the new cheap usb's but I really like using these old ones. Thanks..;. Last edited Apr 25, 2022 Mar 16, 2013 164,217 14,616 184,590 3 Thanks USAFRet, for the quick reply. I've tried those and they don't provide power to the Keyboard? but I appreciate the link. Mar 16, 2013 164,217 14,616 184,590 4 Thanks USAFRet, for the quick reply.

Maybe not this exact one, but similar. 5 I've used several of these with old keyboards, no problem. Maybe not this exact one, but similar. Yes, these work with a USB keyboard in to the USB to PS2 adapter, not what I'm looking to do.? Mar 16, 2013 164,217 14,616 184,590 6 Ah, sorry...I was reading this the other way around.

You need this adapter or, this one gives you BOTH PS/2 sockets for keyboard AND mouse These certailnly should work - the electrical lines on a USB2 port are the SAME as 4 of the pins of a PS/2. So if the old keyboard did work on a standard PS/2 socket, it should work on USB2. UNLESS, of course, the keyboards were used on mobos that had NON-standard PS/2 sockets or electrical power supply lines. Drivers - well, there could be an issue. IF the keyboards was a "standard" one, the generic Windows keyboard driver should suffice. BUT if it had special features that required its own driver, the old driver is VERY unlikely to work in current Windows, and might not even bother to look for the keyboard on a USB2 port. 9 So you have a keyboard with a PS/2 5-pin DIN connector on its cable, and you want to plug it into a standard USB2 Type A socket.

Thanks Paperdoc, I'll check them out online and maybe try one. I'd still like to find out who's done a mod with a usb cable and replaced the ps2 cable and if it worked? But I think this will suffice.

A USB to PS/2 converter is not a straight-forward wiring pin-out adapter between the 2 different connectors. The converter contains a small chip that talks PS/2 either the keyboard or the mouse version to 1 connector and that acts as a USB device which involves being able to correctly respond to various USB commands to the other connector. This USB device must among other things identify itself to the computer as either a "USB HID mouse" of a "USB HID keyboard" as appropriate. There are converters that have 2 PS/2 connectors so you can connect both a mouse and a keyboard to 1 USB port. Internally such converters identify themselves to the computer as USB device with 2 sub-devices the USB standard allows for this. Allegedly there also exist "smart" converters that can work with either a mouse or a keyboard and will auto-detect what is attached. I have never seen one myself so I can't tell you how well that works. Confirm your age You must be at least 18 years of age to enter this section.
