John Sutherland responding to John Aeberhard: I have just finished belatedly
reading your interesting article about the story of LEO and thought you might be
interested in a further development of the story. I started to work for ICL in Dalkeith in 1972
As I understand it, at some stage between then and 1975 when I left, some of my
colleagues were working on a project to put LEO onto the 2960 (I think) for the Post
Office. Apparently, the Post Office unions insisted on retaining their existing LEO system,
so my colleagues were microprogramming the machine, which was also capable of
running VME systems to run DME/LEO
