During the visit of Rene Brun to Fermilab (Sep 8-25, 1998) we investigated a number of technical issues about ROOT in order to provide additional input to the RUN-II Steering Committee. The PASREC committee was asked to extend its charge to conduct these investigations, and was augmented by some additional technical experts. Rene was extremely coopertaive in helping with the techincal investigations, and his comments (together with those from other members of the ROOT team) are linked in with the reports. The areas of investigation are listed below, follow the links for the reports.
