This is the box for the product. As shown in the photos, it states that Windows 3.1 and Linux are not supported. Elecom PC Switch KVM-KP2N ■ Please judge the condition from the photos. The inner box has been discarded. The box has been folded, so when packing, I will wrap the KVM-KP2N in bubble wrap and put it in the box. There are also places where masking tape is applied, as shown in photo 7. Shipping will be via Yu-Packet Post. ■ I used it to switch between a PC and a Dreamcast (a VGA-compatible game console). ■ Since I was using it with a model not covered by the operational guarantee, please only purchase if you are okay with that. It worked without problems when I used it, but it has been over 10 years since I last used it. It's an old item, so please consider it as junk. ● The manual is readable. I think I've written everything I can, so please refrain from questions, comments, and inquiries about functionality.
