I've hot-plugged ADB keyboards and mice after boot (mostly when the wire fell out or I forgot to plug them in) on numerous occasions and had them work fine. I know you aren't supposed to, but sometimes... well I can't be bothered to do anything else. [] ]'>

I use Belkin PS/2 adapters on my Suns and they work pretty well. I wouldn't use one of their KVMs if you paid me thogh, they are pretty aweful in general. I tend to sway for enterprise KVMs, either HP/Compaqs or Avocent (I think my Compaq is actually an Avocent inside the box). I have a little self-powered 4-port KVM I take to meetings and stuff, but it's a bit more fussy about older signals than the big KVM I use regularly.

If you want a good 8-port PS/2 KVM I recommend you look up the Compaq one, BUT make sure you get a later one with the coloured port stickers on the back. The early ones are much more basic and fussy about video signals (SoG for example will crash my older black ports Compaq one I used to use). The OSD on the Compaqs is very cool, on my current one it even has a mouse pointer and draggable window. It is a 'smart' KVM though however, and so it mashes up inputs and outputs, it'd be no good for hacking to use with ADB. I dread to think what it cost new [] ]'>
