I/O Map
The I/O port addresses of the processor modules superMOPSpro are functionally identical with a
standard PC/AT.
An additional I/O-port is the GPCS, which has the standard location 0050h. This port is decoded only
with 10 bits, therefore some adresses of the I/O-address space can´t be used because of mirroring.
The mirroring will occur every 400h starting at 450h, 850h etc.
