I worked in the RCA "R&D" group (about 30 employees), at the Sherman Drive plant, from Summer of 1970-1973 (while in college), and permanently to Dec 1975. Our R&D group, on the 2nd floor of the engineering building (the CED video disc group was on the 3rd floor) designed a VCR that was not a VHS or Beta type mechanism, although the electronics were similar. There were 2 production runs (Rockville Road plant) strictly for the purpose of testing consumer interest and use of a VCR. About 2000 total units were made and put into the field. RCA closed this group down in 1975, and decided to go with the VHS standard, and get all of these machines from Japan. I then quit and moved to California, where I continued working in video.
The huge manufacturing plant was all one giant room (4+ football fields long), with sections devoted to printed circuit board manufacturig, to injection molding, metal stamping, to product assembly (audio products only). it was amazing to walk througjh this giant space and see all of the work being done there. It was also very clean, and noisy! They had a complete metal shop in engineering, where you could make any kind of chassis parts, even for "G" jobs. There was a huge anechoic chamber for testing loudspeakers. There were about eight 10'x10' RF screen cages for eliminating all radio & tv signals. There were demo rooms in engineering where you could see the futuristic prtotypes of TV consoles that appeared in magazines like Popular Science and Ppoular Mechanics.
Engineers could eat in "The Hoosier Room" for lunch; a nice excecutive restaurant located near engineering and the executives. The main long hallway connecting these areas had carpeted walls. The food was very good and inexpenive. It was a great place to be an engineer. Whatever you needed, you got.
