Hi Again;

You know, what you are looking for is not all that hard to do with an external serial RAM. The new serial Ramtron units I just got in might be the answer. Once you set up the address, all you need to do is present the data to the serial pin and give a clock. The addresses are self incrementing after groups of 8 clocks, and work their way from (whatever) starting point, wrapping at the end back to the beginning, all without any timing "hiccups". So for you, and SX with one of these; a tiny bit of software to get it going, and a big bit counter so you stop before you over-write.

A bit more software to get stuff out again, or replay it serially in real-time, or at some other speed, or even by push-button one bit or one byte at a time.

Sounds like a fun and useful exercise.

Cheers,

Peter (pjv)
