system. All game ports use the same address (201 hex), and a joystick
will not work properly if more than one device in your system is using
that address. This address cannot be shared. A computer that has two
game port circuits will cause a dilemma when a game requests infor-
mation from the game port because two devices will “talk” at the
same time. With two active devices on the same address, you will
experience a conflict between the two circuits.
If your games are behaving erratically, you may have a conflicting or
malfunctioning game port. Some cards - multi-I/O cards for example -
have game card circuits but no external joystick connector. It is the
interface circuit that causes problems, so you may have a conflict
without actually having another visible joystick connector.
To correct a conflict, remove or disable the conflicting device, or
change its base address. See the manuals for the other cards in your
computer (e.g. game, scanner, tape backup, or multi-I/O cards) for
information on disabling a game port or changing its base address
from 201 Hex.
