Many thanks to all who provided the inputs I lacked to evaluate my irresponsible Pic paralleling.
As I look at my first creation I no longer see a thing of beauty and a joy for ever but a sneaky little generator of random pulses, a sheep in pyromaniacs clothing, even a battlefield of electronic warriors never knowing if they are attacking or defending and the rules of battle changing 2,500.000 times a second. I mourn the generations of ill assorted gates harnessed together for decades now, rise times all at odds as they attempt to provide some designers vision of enough drive for the next stage. Perhaps an organisation for the prevention of cruelty to silicon might be in order :-)

p.s You can't put me off Pics so easily. I like 'em.
