Inspite of the skepticism with which this first text will be greeted, BY THOSE WHO WILL NOT SIT DOWN AND TAKE THE NECESSARY TIME TO COMPUTE THE STATISTICS QUOTED HEREIN, ˙the systems described herein have been hardware tested and work - better that you expect! [HARDWARE DOES NOT LIE, ˙IT WORKS OR IT DOESN'T.] I am not offering THE GOOD OLD FAMIL IAR THINGS. I can write from now until doomsday but if you do not take the ˙time ˙and EFFORT to read what I have written, ˙my time has ˙been totally wasted. Book 1, which you are about to read is the result of writing the same material many times over. ˙I ˙have had no help in this effort and ˙am tired ˙of ˙correcting and rewriting the same material time ˙and ˙time again. So if you find typos just remember I am my own and only proof- reader. Write me and tell me know in which paragraph of which chapter you found it or them, and I will correct them ASAP. There ˙may be material which you find obscure or confusing. ˙Tell ˙me about it. ˙If it's the result of something I wrote badly then it must be ˙re-writen CLEARLY. ˙If it is an individual problem, ˙and you ˙are registered with with me, I will try to straighten out your problem.
