Kai....

I hope that your not upset or offended by the way this subject has deteriorated.
I agree whole heartedly with what you have said,and with Erik.

I do not believe Kai has!.. but I would.

Paul... over many posts you have shown an intention to use old antiquated chips rather than purchase modern parts.
Even If the book you are working to uses old ideas ,old circuits ,old parts...that does not mean that you have to.
Why make things hard for yourself.

Why damage your education/experience by arriving nowhere quickly.

If you had bought a kit in the first place (say from Kanda or eqv) you would have been writing programs already ,not sulking over a lack of progress.
