Hi all,
I am still struggling with getting this programmer working... It is very
frustrating to be so close, and yet so far! I have stepped through the steps
below and everything seems correct. The only thing I was unable to do was
test the parallel port using the debug cmd. How does this cmd work?

The circuit also appears to be correct. The one strange piece of behaviour
is that the green LED switches on as soon as I plug in the parallel cable.

I am very lost... any suggestions?

Thanks
James Fitzsimons
