RE: Keyboard Port Power and M1

You could do it.  But you must protect your motherboard from surges that 
may occur between the M1 and the computer.  If you create an isolating 
circuit between the two, you should be ok.

Serial port pinout:

The parallel port might be a better option, most have this sort of 
protection already.

Check out http://www.geocities.com/SiliconValley/Bay/8302/ for the 
particulars.

What is the volt/amp on a PS/2 port or a serial port?
I'm looking to drive my M1.  Any other batteries that
work well will also be appreciated.
