I have the original servo-to-go card, and it works. It does not have
Estop circuitry, so you have to add all that. It has a wierd quirk
that causes position information to sometimes be incorrect, and
EMC had to have a software hack to detect and throw out bad readings.
It doesn't have an interface to the solid state relays that you will want.

I have a board set for servo systems that solves all these problems, and
is less expensive for a 4-axis system, too. See
http://jelinux.pico-systems.com/PPMC.html for more info on it.

I think you want to keep your original servo amps. Do you have the
NC-400 amps? I just helped set up an R2E3 with those, and figured out
how to interface to the fault and enable circuits on the amps.
