Thanks for that idea, I did get the other code running but the clock wasn't set right so I wasn't seeing any pulses. I might try that idea in the future.

 What I do, is to set up an array of bytes in memory, each holding a
 0-255 value for pulse width.
 I add this to a minimum pulse width, and create timer values.
 
 I start all the servo pulses at once, then turn them off at the
 appropriate time using a single timer interrupt.
 
 So the output looks like
 
 AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
 BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB
 CCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCC
 
 and so on.
 
 Then the framing pulse (15mS or so) is just a do-nothing time.
