Amazing what could be done!
In 1986 I was working in famine relief for Save The Children in western Sudan. The massive aid operation was run on a handful of Amstrad 8256s and 8512s. We did all the accounts, word processing and survey data bashing using them, with a crack team of local people alongside the expats. They were wonderful. One little-known huge advantage of them over more sophisticated kit was how tolerant they were of the extremely dodgy and variable mains electricity we had to run them on.
