It has been a while since I've studied that, so maybe I'm not remembering correctly. I remember at one time I gave up with it since my preferred target for transfering data between the C64 and the rest of the world is one of my SX64s so, no tape port on it. > >> Sorry but the documentation about C2N232 could be a bit better maybe :) > > > It is not a commercial product. :) sure, I didn't want to imply that. It just seemed to me that was abandoned more or less when ported to the tiny2313 maybe? I didn't find a complete schematic of the new version IIRC.
