Memory sticks? All USB ports were disabled. Only one external optical drive per Directorate, kept under lock and key. In 1993 we were told we'd 'lost' 3 or 4 laptops. No we haven't, it's 14. And they're not lost. They've been cannibalised for spares and in any case they were classified as consumable. Common sense prevailed. Same situation at DRA/DERA. Handed out like confetti, even to consultants, and quietly forgotten when they became QinetiQ. I know one chap who has kept his all these years just in case. Remember Windows 3.11 on 33 floppies?
