Prospero Software

A software company founded in 1982 in London, England by Michael St Clair Oakes and George Anthony "Tony" Hetherington, specialised in making development software for British home computers such as the Sinclair QL but when that market started to dry up the company ported its most popular tools to the IBM PC. The company closed down in 1998 but mr Hetherington continued selling and supporting the products under the same name as a sole trader.

We believe mr Hetherington is the same Tony Hetherington that used to review computer hardware for Personal Computer World in the UK around 1980.
