        Ron, 

                Its nice that you can figure out which pins do what
             and make your A500 work with your printer.  That no 
             problem because your printer has its own power supply.
             However, I was designing a piece of hardware which was
             going to use the parallel port but had to switch to
             the joystick port because the A500 parallel port is
             UNPOWERED!  This is a major bummer!  Got a reasonable,
             marketable solution???

                I think this was done to make the PAR port IBM compatable
             so the 2000's wouldn't need to support 2 types of PAR ports,
             but I have not looked into so I don't really KNOW!

                                                Thanks,

                                                        Wade.
