You could probably extract this information from the information at
ftp://ftp.merit.edu/nsfnet/statistics.  The pnets and bnets files
should give you a good approximation of the number of nets (actually
the number of nets that actually sent traffic).  These go back to
1988.

Otherwise you could find out if someone from Merit can dredge up stats
from the PRDB which are allegedly on tape somewhere.
