QAM256 (or any other such technique) depends on a consistent, almost predictable, level of noise. I suspect cassette noise is truly random so it would drop back to lower levels, in the end a single binary bit and just get the speed we used to get.</div>

higher throughput from a cassete. I wouldn't be surprised to see 200kbps <br>

slower than floppy disk. Even using something like Speedlock would only take that down to about 10-11 minutes.<br>
