Thanks for checking on that, Tobias.  As far as I can see that tar
file contains the data from the High School and Beyond study (HSB) in
appendix a, the EG data set in appendix b and the THAI data set in
appendix c.  These are the ones available in an ASCII format.  Other
data sets are only available in a SAS format for a VM/CMS machine
(interesting concept of "portable data format").

One can convert these to R data sets.  The EG data are already
available as egsingle in the mlmRev package and a truncated version of
the HSB data are available as Hsb82 in the same package.  The THAI
data can be converted as shown in the enclosed.
