7I96 vs 7i76e was created by ihavenofish
I am building up a machine with a lenovo USFF M90P

The PC will NOT run the mesa 5i25. Something to do with PCI power levels. I can get a PSI Ethernet card for it, so i can run one of the mesa Ethernet cards and still have networking. The PCI card is realtek and the on board Ethernet is intel. I assume its safest to use the intel one for linuxcnc.

The machine will have 4 axes, a tool changing spindle with static tray, and an mpg wheel, limits, and not a whole lot else.
Would i be better off just getting the 7i76e, or will the 7i96 do everything it can do with less IO? The main thing i don't see on the 7i96 is MPG support "yet". Is this on its way soon? (as in, a few months).

I plan on trying to stuff the mesa card INSIDE the lenovo machine to make this machine "cabinetless" so the smaller board is helpful. Cheap is also good :P

Thanks

You can use a software MPG counter on the 7I96 inputs (a hardware MPG counter is already available in the firmware but still needs driver support)

Note that this will eat into the rather limited 11 inputs on the 7I96 unless you use the (un-isolated/unprotected) expansion port pins

OK, so i am probably best using the 7i76. I wonder if i can stuff that in the lenovo case.. seems unlikely. I only really have the space where the slim DVD drive was.
