4 - ICT/ICL 1900 in the Market

 

 

4.1 – 1900 deliveries (Road Map)

 

The following chart was presented by Brian Procter and Virgilio Pasquali, after extensive research, at the ICT/ICL 1900 seminar in May 1996 (Science Museum – London).

It maps the delivery period versus performance of each 1900 model in its successive manifestations (see Sect.1.4), the relative position of the successive enhancements and their relationship with their predecessors and with each other.

The 2903/4 and the ME29 Ranges, though not, strictly speaking, part of the 1900 Range, are included for completeness.
