You know, the funny thing here is that the computer programs all ASSUME that 
you are using a
Yaesu G5500 rotor.

It might be time to do some development.  A FodTrack hooked to a PIC could 
be a very simple solution.
Program the pic to run your pulse actuators, battery back it up so it 
doesn't lose count.
Use the output (either serial or parallel port) to tell the PIC where the 
actuators should point
and have the PIC do the conversion, flop the relays and move the actuators.  
Actually, emulating the Serial port version (the Yaesu controller) would 
allow other programs to track as well...

Its work, but it shouldn't be impossible to do.  I though W0LMD had options 
for pulse actuators in his trackers.  If not, he should be willing to add 
this.
