Hi ,
I have an Orac and Colchester I intend fitting MPGs too.
I will fit 2 hand wheels so that it can be operated like a manual machine..but "fly by wire"
For the additional inputs required I have a Pokeys expension board (my Parallel port BOB has not enough spare IP)
I'll wire the quadrature o/p from the encoders to the Pokeys board then configure Mach / pokeys to do the clever stuf.
One thing here - I hope the pokeys firmware is fixed to accept the high pulse rate from a "whizzing" handwheel !
From the informationon the "pokey thread on this Mach forum" its looking good so time to see for myself.
ATB
