This is a wired (USB) keyboard from Sanwa Supply. I purchased it several years ago and used it for a few months, but I haven't used it since then, so I'm putting it up for sale. I purchased it 8 years ago. It works. Please check the details in the images. I am looking forward to your purchase, understanding that this is managed by an amateur. ◇Instant purchase available◇ The following are compatible models from the product page: 【Compatible Models】 Windows PCs (DOS/V) from various manufacturers *However, models that have a USB port and whose PC manufacturer guarantees the operation of the USB port.
