Another great teardown.
The first computer system I worked on had four racks for the PDP-11-20 computer and four racks of special build electronics for capturing digitized images generated by a laser system.
As for memory costs, we upgraded to an additional 8K by 16 bits of core memory for about 8,000 USD. That was 1 USD for each 16 bit word.
Later we got an additional 2.2 MB disc drive with one 1.1 MB removable platter. Great upgrade from our original 64 KB hard drive.
How times have changed over the last fifty years.
