USB keyboard on an Octane?

USB keyboard on an Octane?
I want an Octane and a Tezro to share one screen / keyboard / mouse.

Both systems have DVI output.

KVM switches with DVI, supporting a 1920x1200 resolution, want me to use USB peripherals (some KVMs for DVI + PS/2 exist, but they have oddball resolution limits like 1600x1200)

The Tezzie should work fine with USB keyboard and mouse, but it seems I need a device to emulate a PS2 keyboard (scan set #3!) and a PS/2 mouse to place between the KVM and the Octane.

Does such a device even exist or do I have to build something myself using an Arduino etc?

RE: USB keyboard on an Octane?
I used to use old (cheap) netgear KVMs from like 2006, they were VGA & PS/2 based, it was more hardware-ey. So really it had mouse and keyboard emulation to prevent disconnects, but the video really did just switch from system to system so an normal SOG monitor was still required. But it worked. The cheaper the PS/2 KVM the more is seemed to work...

I was thinking of looking into old Raritan stuff for IP-based KVM.

RE: USB keyboard on an Octane?
Yeah, that's what I want to do on the other side of the room, where I have a dozen or so systems of Indigo ~ O2 vintage. At my desk I have the Tezro, an Octane2 V12+DCD (and an Onyx2). I don't want to dumb down the crispy digital goodness to VGA, run it though a switcher and then to an LCD screen.  I have an ATEN CS1784a (USB + DVI KVM) I have successfully used in the past with my prototype Fuel mixed with some PCs. I even have a genuine charcoal SGI USB keyboard and mouse ...

Now that my wiring project is basically finished, this keyboard / mouse / screen problem is the final puzzle to solve. I wouldn't mind to unload some of these big fish tank CRT screens.
