 I have an old demo I got last year from Germany, it is a digitized song
 by Queen, about 3.5-4 minutes long.  It is done on two amiga floppy disks!
 not even hard disk, the floppies can keep up with the sound if you spool
 it into the amiga in large enough blocks.  The program that plays the
 song is only about 3K, probably in assembler, Lattice or Manx back then
 wouldn't make object files that small.  So it can be done pretty easily
 just allocate a block of chip mem, say 64 or 128K, and feed from the
 disk, start sound I/O, or maybe two 64K's and double buffer.  I played with
 it a bit last year and it isn't really that hard.

To program is human, to debug is something best left to the gods.
"Spitbol?? You program in a language called Spitbol?"
  The reason computer chips are so small is that computers don't eat much.
