TTL homebrew CPUs

Wakkkyness is not dead.

"The Madscientist Builds a Processor"

is the tale of a *second* electronics project,
    the first was a one chip  TTL counter.
Randy thought that was not hard,
    why not try a computer?

He learned: 
    - add lotsa capacitors between +5v and gnd, all over 
    - ground can jump up and  bite ya
         (a ground plane is a good thing)
    - and a lot of other practical stuff
but crashed on, 
        and finally succeeded  :-)))
