I discovered something interesting.

I have a switch box at home so I can share 1 mouse, keyboard and monitor   
among 4 computers.  The switch-box is a DIN-5 style, so I use a DIN-5 to   
PS/2 connector converter.  This has always worked flawlessly with my PCs,   
but the UDB complains that there is no keyboard connected and defaults to   
the serial port.  I tried numerous combinations and one when I connected   
the PS/2 keyboard (curiously enough, I have a IBM PS/2 keyboard -> DIN-5   
adapter going into the switch box) to the Alpha, up it came!

I realized that the PS/2 connector has 6 pins where the DIN-5 (obviously)   
has 5 pins.

So what feature does that 6th pin provide to the Alpha?  Just curious.
