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

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

Source code and executable will be released on Aminet under mus/misc/stardust_amiga.lha next week.

PC users spend $3,000 on Sound Blasters and Pentium chips and still can't do what a $500 Amiga was doing in 1985.

Download failed on Aminet mirror. Can someone mail me an ADF floppy disk image?
