Since you cannot have access to all 25 pins because a lot of them are
the ground, if you really need more than the 11 pins available on the
parallel port and if your application doesn't need to have an external
drive connected, you can use the external drive connector nearly the
same way you use the parallel one.
You have an example how to access the parallel port directly (the legal
way) using the Aztec compiler on the Fish disk #73: "ParOut".
