I thought I'd launch a new topic for this as it asks some new questions regarding the Cassette port on the 64.
In looking at the Reference Guide on this port, some questions are raised about just how the read/write pins work and the type of data is being sent and received.
Interestingly, the reference guide starts talking about how to open communication with a modem, then jumps into two sections about talking with the tape drive. Are the data lines send/receive serial communication? If so, at what speed? This has got me thinking that a programmable microcontroller like the ones I'm playing with might be able to very easily communicate with these pins for storage purposes. Wouldn't be as fancy as the current MMC/SD solutions, but the experiment sounds fun for the learning process.
Is there more information on this port any SSOC'ers can share?

I'm sure I've read some good articles on the subject, but I can't seem to find anything with much depth online. Must have been in a magazine somewhere. But yes, it behaved much like a 300 baud modem. Of course, faster speeds could be had be writing to the tape in a custom format, and then writing a customer loader. I think you'll definitely be interested in checking out this project: www.zimmers.net/anonftp/pub/cbm/transfer/C2N232/C2N232.html
