Hehe, I suggest you go to the computer city to buy one and change the keyboard port into a USB port adapter, because your keyboard is a USB port, so don't toss about where the round port is connected. If it's connected, it won't come out.
The round socket with keyboard and mouse inserted in the back of the computer case is called PS/2 interface.
As long as it is a USB socket, it can be plugged in, without distinction. USB interface standard is unified.
You can also change the keyboard round head to square head (USB). The steps are as follows: Carefully study the pins of the two interfaces. PS/2 has 6 pins, while USB has 4 pins, both of which provide +5V voltage.
Generally, CD-ROM/DVD-ROM drives now have SPDIFOUT interfaces. If there is a SPDIF interface on the motherboard or sound card, you can connect it with a dedicated SPDIF line (digital audio line 2PIN+ shield).
The keyboard interface of the round plug is called PS/2 interface, which can be plugged into the corresponding interface behind the desktop host. If the host does not have this interface, you need to buy a PS/2 to USB interface adapter. The round mouth of computer keyboard is called PS/2 interface. The flat mouth of computer keyboard is called USB interface.
