Ahh, if that's the case, I would agree. I understood the original
suggestion was to implement the tone detection in firmware in the

Well
yeah...anyone who would replace a single 74LS00 with a
microcontroller would certainly earn a "moron" sticker on the
forehead.
Hang on a sec...
Back in the 'decoding FSK cassette data' theard, somebody suggested 'a
couple of tone dectors and a microcontroller' I asusme the 'tone
detectors' are soemthing like an NE567. In whci case the logic to
combine
them into a itstream is only a few logic gates.
And I still feel that the bast way to impleemtn that logic is not a
microcontroller.
