The 7i76 would indeed be a killer product for some uses. But its lack of sufficient encoders is also a road block. With 32 spare inputs, it could certainly dedicate 12 of them to accommodate 4 of the MPJA dials (They are single pin per signal ttl level dials) and/or put servo's on a 4 axis machine such as the 6040. I'm already useing 2 of them in newer interface builds, driven by 5i25's and the thought has crossed my mind to ask Peter to make me a 5i25 load that puts more encoders on the 5i25's p2 connector since I have not yet used a p2 connection on anything but the G0704, and there is a need for more encoders if I am to put a tool changer on any of my machines. those 5i25 p2 connections are used on the GO704 only because they were already on that BOB, home and gear tallies mainly. They could easily be moved to the 7i76, freeing up the p2 connector for a totally bidi input/output on any pin, and with 17 pins, 4 dials would work nicely. And I'd still be inside the available i/o of the 7i76. Pins to spare for driving a tool changer. Absolutely a loverly idea. -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
