If in doubt check the manuals of the adapters installed in
the PC.
Remember, only DIP switches 2-8 have any effect on the
PC IEEE card. It is straight forward to work out the I/O address
since DIP switch 2 is connected to address line A2 and so on till
address line A8 is connected by DIP switch 8. The 'ON'
marking on the DIP switch is a misnomer since the address line
is selected low in the ON position.
In all the PC IEEE may be set to one of 128 possible i/o
addresses. Only a representative sample are given.
