[Coco] Coco Cassette interface help

[Dave Philipsen]

You don't even necessarily need a DAC to create these signals.  All that is needed is a simple analog 'wave shaper' circuit which rounds the edges of square waves so that they essentially become sine waves and are then easily recorded on a budget tape recorder.
