I did the same when I did mine....had a lapse along the way and screwed up 
the signal to pin mapping. As long as the daughter boards match the cape no 
probs. In my defense I was looking after a Beagle pup we got at 8 weeks 
old. 

There's also the raw pins brought out for the ADC, an I2C bus and for an 
external power switch.

I don't know if you've seen my spread sheet but I've thrown it up 
(hopefully without any major typos). With a bit more thought some pins 
would have been better elsewhere, but I was aiming at a simple conversion 
from a 2 port PP setup. Hence the "output daughter board" resembling a Std 
PP and the Input resembling a PP setup for input.

I figured that the main cape could be used on it's own for experimenting 
with external devices without the daughter board.

But I'd be interested to see your progression, as I have time on my hands 
now as I stopped the Linuxcnc Mint ISO's, the devs prefer seem just to 
support Debian. So you want someone to bounce ideas off my old noggin is 
pretty hard & dense.

Cheers
Rob
