ICL is basing its Clan Unix strategy on third party applications implemented at its porting centre out in Slough. It believes that the 100 or so such applications implemented there and at other centres around the world – in France, Germany, Holland, New Zealand, the US and Ireland – will attract customers. Programs now available include such products as Informix, Ingres, Today and U-Backup and ICL says that around half the third party work done at Slough is Unix-based – and Unix seems to be the favoured future its 6,000 or so System 25 users.
