4-port KVM switch for sale...

[Arcmanov]

Its a TRENDnet 4-port PS/2 KVM switch, with audio.  You can use 4 PCs simultaneously
with only one keyboard, one monitor, and one mouse.  Hence the name.

   

Just over a year old.  I got a USB/PS/2 version so I don't need this one.
Should come with 4 sets of cables, but you only get three because the video
on one of the cables is faulty.  (You can get a replacement cable on Amazon if you have to)

All the ports work splendidly though.
You also get the power adapter I purchased separately (it doesn't come with one).

Asking price $400.00

Interested parties, you know the drill.
