PIL-Box and HP-71b

[salvomic]

hi,
my new PIL-Box will come here Monday (tnx Jeff!).
I'll use it to connect both my HP-41CX and HP-71b and to make some experiences...
Any help and hints appreciated (in the mean time I'm reading the links in the Jean-Francois web site and other stuff).
• In 41CX I've the HP 82160A HP-IL interface with its two cables (in, out)
• In 71b I've the HP 82401A HP-IL but with only a cable.
• I've also another cable to cut to set in the PIL-box.

With the two (half) cables in the PIL-box I can connect HP-71b alone (or HP-41CX alone), but I wonder if it is possible to connect both calculators in the same loop with the PIL-box to pilote them together (one or another but in the same loop) from the computer.
If yes, I wonder if I need another cable for HP-71b or I could use it the same with the only cable I have, making the loop -41-PIL-71-

Thanks for info (at the moment I'm a newby with that toy)
