This isn't a filing cabinet but actually where the tape drive and memory modules for the Elliott 803 were housed - the core memory can be seen in the centre of the cabinet.

The Elliott found an unusual source for its reels of tape. The National Museum of Computing's Murrell explains: "Elliott the company was in Boreham Wood in North London and when they needed to find a source of tape they actually went to the film industry because this is actually 35mm film stock but subsequently coated with a magnetic coating and then loaded into the front of the tape drive."
