So going over all the things I can easily do data integrity checks on, I've
run 'gzip -tv' on all the GZip'ed things and found three that are apparently
damaged:

gzip: ./PDP-11/Distributions/dec/Ultrix-3.1/ultrix-3.1-bootape.tar.gz:
              invalid compressed data--crc error
gzip: ./PDP-11/Distributions/research/Ken_Wellsch_v6/v6.tape.gz:
              invalid compressed data--crc error
gzip: ./PDP-11/Distributions/unsw/90/record0.gz:
              invalid compressed data--crc error

I can't comment on the *.Z compressed archives as they do not do any crc.

I will have to peruse my stack of archive CD's made at various stages of
the archive to see if I have the other two (I have a good 'v6.tape.gz' file).

I did not try and run the MD5 list yet.  But this is an example of why I
had been pushing for the use of MD5 for all items in the archive...  B^)
