Thanks for the reply Charlie; That's my next biggest question.
Lyle spoke of " adding to " or " modifying " the board with additional
components. And your term " taken the time to build up " Once I get
that little circuit board full of parts out of its box; I'm gonna
be standing there looking at it and saying " now what ? " I'm pretty
much convinced I'm ordering the board, and any other computer related
parts will probably be on hand or at Radio Shack.

OK; that answered those questions, so ; I've already made progress.

I appreciate your input. 73 for now:::
