KVM between A4000T and PowerMac

[ferix]

Well... I think the only option is to "degrade" your G4...
I mean, use one of these http://www.dealextreme.com/details.dx/sku.478 for the mouse & keyboard, and one of these http://www.dealextreme.com/details.dx/sku.8312 for the VGA.
Then, you can use this KVM: http://www.dealextreme.com/details.dx/sku.718
And don't forget to buy the cables: http://www.dealextreme.com/details.dx/sku.10109
 
The USB to PS2 is pretty compatible, as the DVI to VGA.
And the final bill should be as follows:
 
USB to PS2: $2.95
DVI to VGA: $1.90
KVM Switch: $12.33
KVM Cabling (2): $10.8
Total: $27.98
 
Not so bad
 
Note: I wrote "degrade" because DVI in some cases is better than VGA...

I wonder if a PS2 to USB keyboard adapter will work with the Mac?

I'm sure It works. I use a G3 with a PS2 to USB adapter at work.
You only need to load the propper keyboard map, as a normal keyboard.

There are two possibilities, quickly pressing a key twice, or pressing the KVM button.
The key to press depends on the KVM. Usually Crtl or Alt.
