It's been a long time since I looked at this code.  There's a lot of new
stuff now, and it is more reliable on less-than-perfect tapes.  It only
works on program files, not on data files.  It is not endian safe or 64 bit
safe.  I am not a C programmer.  It compiles on windows with Cygwin. 

Type:

./viccas -h 

for the options.

To build the program in linux, type make.  (In cygwin I used 'gcc -o
viccas.exe viccas.c') The program assumes your audio device is /dev/dsp.  (of
course, it will take much longer to decode a file while listening to it.  on
my K6-3/400, a 4k file decodes in about 3.5 seconds without audio playback. 
If you listen to it, it decodes in real time.)

If you make changes/improvements to this program, please send me your 
modifications.  I would especially like to see someone make it 64bit and
endian safe.  

Most of all, have fun.
