Is the following manuscript publically available?

Dana Scott, 1969, A theory of computable functions of higher type. Unpublished seminar notes, 7 pages, University of Oxford.

There is a discussion of this paper in section 8.1.2, Types as sets, in Cardone & Hindley, 2006 History of Lambda-calculus and Combinatory Logic; additionally section 10.1, Domain theory, traces back to this manuscript some crucial order-theoretic insights.

    $\begingroup$ Well, this is wonderful and thank you - I assume I should thank Andrej as well for receiving this answer. A further question: are the two 1969 titles really used to denote one unchanging manuscript? John Longley, 2010, Notions of computability at higher types I, describes the paper as 7 pages long, while the 1969 parts of the 1993 paper weigh in at just under 26 pages. $\endgroup$ Commented Jun 11, 2011 at 12:41
