[DSP-10] KDSP10 Info

         That all looks in order to me... This flaky problem cropped up 
back when I originally built it, and it had something to do with loading 
timing...I swapped the 74HC575's back then, and the problem went away for 
the most part, unless I did fast large freq changes....It  seems more like 
a timing type problem. I was suggested to check the diagnostics programs 
which I will do, but that proved fruitless last time as it was not a wiring 
or assy problem, but something more elusive...
         I never really did positively ID the culprit, but I may start 
replacing chips and parts on this if I cannot get it to play nice..
