レトロPC　PC-9801VX21にサウンドボード（PC-9801-26K）を取付け

In my recent video I took out the PC-9801VX21 and left it as is, so I installed the PC-9801-26K sound board. I don't think there's much demand for this video, but the 26K doesn't just plug into an expansion slot, so if you need one, please use this as a reference!
