I have hardcopy ODS-1 and ODS-2 documentation.  But it's not necessary 
for the current work; I've identified the tapes by other means.  I'm 
sure Al will chime in if he doesn't have a copy.

No need for further research; thanks.

This communication may not represent my employer's views,
if any, on the matters discussed.
