Notes on porting stardust.c to GCC on Linux 1.2 and optimizing the inner filter loops.

Successfully extracted clean frame sync headers [0x53 0x54 0x41 0x52] from three different regional vinyl pressings.
The original stardust.c v1.0 dropped sync whenever there was a scratch or surface pop on the record.

Grab the source archive from ftp.ashford-poly.edu:/pub/telecom-archives/stardust/stardust-1.3.tar.gz.

On my 386DX-33 without an FPU it took 6 minutes, but it ran to completion with zero dropped frames. Great work!

Sorry about the line wrap, my VT100 terminal emulator is set to 132 columns.

Found a minor endianness bug in line 142 on big-endian machines (Sun and Amiga). Replace ntohl with custom byte swap macro.

Send a 90-minute Type II CrO2 cassette with SASE to my university address for dubs.
