Why ICL Computers ?

I started collecting ICL machines some 30 years ago, as I was then and still am interested in the British Business Machines of our past computing industry. This I felt had not been given the credit and attention that it deserved, also that ICL was in fact the culmination of most past British Computer Companies rolled into one.
It all started with BTM (The British Tabulating Machine Company Ltd).
Below is a poignant reminder of a once great British Computing Industry.
