The opportunity to build on the 4000 series was helped by two important factors - public sector bodies, such as the Post Office and universities, are directed to buy British; and it had a ready made market within the GEC group, whose members are encouraged, although not compelled, to buy from GEC Computers. GEC Computers traditionally has strong links with the university market, providing front-end computers for the ICL 1900as well as stand-alone machines. More recently its involvement with the EPSS packet-switching system and Prestel have involved a number of Post Office contracts for 4000s. the order book for 4000s stands at 260 systems with 200 installed.
