Testing custom audio input routines on an Amiga 1200 with a standard parallel-port sampler.

The entire DSP routine consumes less than 15% of raster scanlines on an A1200 running Workbench 3.1.
When the carrier locks, the program flashes the Amiga power LED to indicate binary frame synchronization!

Does anyone want to test on an unaccelerated Amiga 500 with 512K chip RAM?

Please make sure it's compatible with Kickstart 1.3 for those of us who haven't upgraded our A500s to 3.1 yet.
