Yes this is an expensive operation if you consider this is just one
single addition operation when calculating Bresenham.  I also have in
the background, packets coming in from the parrallel port from a PC,
which have to arrive within a reasonable time.  I think it make take 100
instruction cycles or more to get a single byte from the parrallel port.
I did however calculate my worst case timing senerio of 100micoseconds
max,  and that didn't take into account parrallel loading.  If I can
calculate my next position in less than that, my linear motion can
achieve 10inchs per second or 600 inches per minute.  This is a key
factor in the whole mess of things.

Regards,

James
