Tony Pritchett was an early user of the SC4020 both for his own work and that of the Open University. In 1968, when the purchase of a PDP15 was under consideration, the Laboratory had a number of discussions with David Bickford of the Experimental Cartographic Unit (ECU) who had a PDP15 and it was agreed that the Laboratory and ECU would backup each other in terms of PDP15 support. ECU was, at that time, part of the Royal College of Art and, through that connection, Colin Emmett, Alan Kitching and Tony Pritchett became involved in using the SC4020. Both the ECU and the Laboratory also had D-MAC Digitisers.
Tony already had some experience of computer animation having produced probably the first character computer animation telling a story worldwide, certainly in the UK called The Flexipede at the Culham Laboratory using their Benson-Lehner film recorder. And it had a soundtrack.
Most of his work at the Laboratory was done on behalf of the Open University but he also contributed to the efforts of Alan Kitching and Colin Emmett with respect to ANTICS.
Tony Pritchett died on the 28 August 2017.

Some of the manuals Tony had related to his use of the Culham Benson-Lehner 120 microfilm recorder from the London Atlas and the use of the SC4020 at the Atlas Computer Laboratory:
There is also a collection of miscellaneous papers and other work arising from the exploration of archive boxes from Tony's studio.
