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!

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.

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

If you are posting from AOL, please read RFC 1036 before posting again.
