Scanning through some of the postcards loaned to me by Tommy Gelinas at Valley Relics, I came across this 1963 postcard of a new building at  the corner of Chandler and Laurel Canyon in North Hollywood.

12012 Chandler was the home of “the first Honeywell 400 computer service center in the US.”

The Honeywell 400 was a system the size of a room, so nobody who worked with one carried it into this building for servicing. It was an early 1960s workhorse for processing payroll and other functions of business and industry. According to Kraza, Honeywell was part of a second generation of computers that came of age when transistors replaced vacuum tubes.  ” Transistorized computers were more powerful, more reliable, less expensive, and cooler to operate than their vacuum-tubed predecessors.”

The black and white photographs above show the Honeywell 400 in operation. However, they are not from 12012 Chandler.
