Sure would be nice if it did work. > It might work! Does anyone have access to one of these and the tape controller for the 3B1? I would be willing to try if someone can lend a drive. (Or perhaps the pin-out for the drive first, just to check for design stupidity like putting raw +12V on a pin that the controller thinks is a ttl input or output.) I seem to remember one or two pins on the ground side of the connector being used for something in the floppy tape drive we have. The 40MB version may simply use more tracks, or slower tape speed/denser recording, or perhaps rll :-) ? ? If someone does have access to both ends of the question, please try and post results.
