Re: 6808 <-> 6800 (off topic)

Oh, now I get the question. I never did find datasheets online for them when I
was looking last year. I did get some through a faxback service but don't
remember the company.

So I do have a faxed version of the datasheet but somebody on this list has to
have something better, right?

But, there do not seem to exist datasheets for either the 6808 OR 6802. Only the
6800 and
6809. :-(
