Thank you. Your story is truly impressive, it looks that AmiBroker list is full of talents.
All this computer nostalgia makes me think I am getting old especially when
my 7 year old daughter once said in response to my "when I was a child we only had black-and-white television":
"Daddy, was that when dinosaurs lived?"
Kids have funny sense of time :-)
Best regards,
