Just for the fun, i plug my newly acquired HP-IL module from my HP-41C to my dislike HP-75C; so still for the fun, can i "hadshake" them or send something from one to the other? A friend of mine told me to plug it in my HP-71B but i can't find the IL connectors on my 71B; is it integrated like my 75C or an option card like my 41C.
Same question for the card reader : on my 75C i found the card reader but no traction was made on my cards; what is the command for reading the cards? Where is the card reader on a 71B an option too???
Thanks again
