[comp.sys.atari.st] Atari Parallel Port

dachurch@athena.mit.edu (Douglas A. Church) (04/07/88)

Hi there.  A friend and I are trying to build a piece of hardware to talk to
  his Atari 520 ST.  We want to 8 bit inputs, which the Computer can choose
  between, i.e. it sends out a bit and gets in the corresponding input.  We
  think the best port to use is the parallel port, which seems to be full 
  parallel and thus do I/O (wow, both!).  

So, the questions..:
  1> Is there a better way to do this.
  2> If not, then
    a> can the parallel port input and output simultaneously..
    b> if so, how does one read it from the computer (preferably C or somesuch)
   
Anyway, thanks for the help, this seemed like the only place to put this....

As I don't regularly read this, could all responses please go to

        					Thanks in advance ....
