Gary,

The INIT routine in maf-lfo2.bas contains approximately 1.2 seconds of delay 
in a for/next loop to flash the LEDs on and off, and then another 100ms 
before it even looks for the start signal from either the start button or 
input.  Each of your three PSIM-1 modules may be in a different part of the 
loop before getting the start signal.

Try the attached file.  I modified the INIT sequence and removed the pauses 
and blinking LEDs.  This is as close as you'll get to a synced startup 
sequence.  The ATOM-Pro processes approximately 100k lines of code per 
second.  This is in a tight loop of 3 lines of code waiting for the *start*. 
Should be close enough.  :)

Let me know...

Best regards,
Brice
