"Have pipe, will adjust.... I think this illustrates the (rather finicky) adjustment of the timing of a mercury delay line. I believe that it was accomplished by varying its length, using a vernier screw. The equipment to the right is almost certainly a piece of special-purpose test kit."

Deuce Programme Sheet

This is a single card program that I wrote at MAFF Guildford which allowed the MK II Deuce to be used as a simple 80 column card reproducer. Using this program, programmers could quickly reproduce cards without leaving the computer room thus preventing someone else sneaking in and taking over the ' vacant ' machine. - John Barrett

"In June 2002, John Campbell contacted me from Australia, and mailed me an image of the instruction card for the DEUCE. He remembered working on the DEUCE in the early sixties, before he emigrated to Australia. I got his agreement to display the card on this site"
