The gzipped tarball orig550.tgz
- Dave Platt's unmodified A-code source of Adv550, dated 18 Sep 1984.
- My reconstructions of Platt's original F77 munger and executive
to handle the A-code source.
- A subdirectory of PL6 sources (as preserved in the IF Archive)
- A separate document explaining what's what, and saying a few words
about this package came about.
