I’m losing my mind. This old graphics tablet connects to the PS/2 port on an old PC for power. There’s a separate serial cable for the actual data connection. I want to supply it power without needing to connect it to a PS/2 port, so an adapter for USB would be ideal.
I know others have achieved this but I can’t find the details. Can anyone help? The search results are full of Playstations because it misinterprets the “PS/2” part.
Are you sure that’s not an 8 pin serial connector? It doesn’t look like PS/2 from this angle
The other end looks like the PS/2 DIN connector.

Part number for startech PS2 to usb adapter
Probably won’t work due to the higher power of serial compared to usb though.
Maybe the part I heard about is specially made to account for that too. Hmm. Thanks, I’ll look into it further. Edit: according to this video (3 minutes, 15 seconds mark), the adaptors do work.
You could always look into a PCIe serial card for the serial port, and the PS2 to usb adapter. Still unsure if it’ll work but it’s pretty cheap stuff to test out
Try searching for a “6 pin mini-DIN to usb adapter”
Usually you can’t just patch USB to ps/2 pins. Others called out voltage might not be the same even if you aren’t using data.
I’ve done it lots with stupid simple adapters for things like KVM, back when PS2 was still around but everything was shifting to USB. These adapters were provided by major KVM vendors at the time.
Worked fine 99% of the time (occasionally didn’t).
Now providing power… I’ve never looked at the PS2 spec. OP should check the tablet requirements, make sure it doesn’t exceed what their USB can provide. And verify an adapter maps the power pins appropriately.
