I think I found it in:
Coffin, J.M. (1990): Retroviridae and their replication. In: Fields, BN
and Knipe, DM: Virology.
I just now saw the abstract of an article in the
january issue of J. Virol. reporting relevant data:
Jones, JS; Allan, RW; and Temin, HM (1994): One retroviral RNA is
sufficient for synthesis of viral DNA. J Virol 68(1), 207-216.
Haven't seen the article yet, though.
