in 1987, a prestel admin computer was introduced which supported the user registration process: the capture of user details from the paper prestel application form (paf), the transfer of data to the relevant prestel computer, and the printing of the welcome letter for users. this machine, also based upon gec 4082 equipment, was the first to be equipped with 1 mbyte of memory which was required to support the rapport relational database. this product from logica was an early example of deployment of a system written in a 4gl database language which supported all features of the prestel admin application.
