User KVM for PS2 AND USB?

We have a monitoring station that servers a business purpose for a user that has two computers sitting at a desk.

So there are two towers, two monitors, two keyboards and mouse etc.

Normally I would just stick in a cheap kvm switch that would eliminate two keyboards and mouses. I would leave the two monitors, as they need to be used. I would normally only use the KVM for just the keyboard and mouse toggle.

However I ran into a problem. Comptuer 1 is quite old...there is no USB ports on the machine. It only uses PS2 mouses and keyboards. Computer 2 is newer and only uses USB.

My KVM only works via USB.

I know there are expensive server room ones, I normally only use cheap $20-$30 KVM for user situation like this where there's only two computers. For example I normally use these for a cheap solution for user computers for things like this:


I can't seem to find on that fits my situation.

Can someone link me a cheap KVM that would work for with one being a PS2 and one being a USB?

Put an inexpensive add-in USB card in the old PC ... then you can use a USB keyboard/mouse for it as well.    Then your KVM will work fine.

I thought about that too, but this is a very unique server hardware and modified Unix OS that wouldn't play nicely with any modification with something like that. :(

I've yet to see a Linux version that doesn't support USB ... sure wouldn't hurt to try it (for $8).

Other option is to add PS/2 ports to the USB computer (probably pretty hard to find a PCIe card with PS2) or get a USB to PS/2 converter - for connecting PS/2 keyboard and mouse to USB system.  Then you can use a cheap PS/2 KVM.

Lots of adatpers,

My people would kill me if I tried to combine their systems onto a single keyboard/mouse.  We just give them the space for it on the desk.  For how they use the two systems I think it is more efficient.

I guess the main reason why it's not possible is because of the case and mobo doesn't support these types of additions. It's like a 20k monitor tower that's highly specialized. But It works decent these kvm type devices.
