If you have a desktop or a tower AMIGA you can insert the card inside
them. In this case, you don't need my powersupply.
Put the card in a metalcase, that is the shield for the other
components inside the computer and against them.
Connect the shield to the analog ground (GND).
The digital ground is the pin 7 of the serial port. Don't connect it to
the analog ground (shield). There can be a difference up to 1,4 V.
You can use the intern computer-power-supply for the card.
+5 V - normal red
+12 V - normal yellow
-12 V - normal blue
ground - normal black (analog ground for us)
You MUST test this with a voltage proof tool.
If you put the wrong voltage to the card it will die - certain !!!!
