Hi guys,

I'm currently taking digital lab.  The course requires that you build
a circuit at home and come into lab and test it with a power supply.
I also realised that the ports on the back of the Ami have pins with
+5V, gnd and -5V which I require. I also need about 5 inputs (say
a,b,c,d and e which can be either on {5V} or off {gnd}). Is it true that
the parallel port has seven pins which could be used for this purpose?
Now the questions.

Is it safe to do the above?
Is it indeed better to use the parallel port? My serial is taken!
Is there software that allows you to set the pins on high or low already
out there?
If not which language would be ideally suited to do this kind of stuff
on?

Any warnings, comments, prog. examples, flames, are welcome to


Thanks folks.
Bin
