Hi,
Years ago we used the serial ports on the Amiga's so that we could transfer games back and forth, if you look at some of the old books you will see that you have to cross I believe the TX and RX lines on the serial cables, but I believe this only worked on two amiga's or one amiga and one PC. I know at one time we had about 4 amiga's all talking to each other but I can't remember how, since it was just about 2 weeks after we all bought amiga's (A1000). For the life of me I can't remember how we did it, you know old age and all that. Sometimes I wonder if I can even figure out where I put the old miggy and I don't think I moved it in 4 years, if I remember right.
