My dad worked in a substation in the 90's which had the aesthetic of many of these pictures. Wall to wall switches which controlled the power distribution to half of New Zealand. Halfway through the 90's they upgraded to a few boring beige boxes in an office, and there was no need to use the manual switches. I loved going there because his workmates would give me pirated MS-DOS games on floppy disks, but the magic was lost. Later on they restructured all control through a single office in the capital and my dad lost his job.
