Computers and the law
I just came across an 1977 issue of the legal journal Case and Comment, which has an article about using computers in the practice of law. It casually mentions that they are the size of a refrigerator, and can be used for word processing and billing. "A computer capable of doing the operations cited in this article can be obtained for about $25,000. [$99,000 in 2016 dollars] More advanced models may exceed $300,000 to purchase. [upwards of a million in modern money]"
Software would cost $2,000 to $10,000 -- $8,000 to 40,000 in modern terms.
The first legal computer I saw was in the office of Margrit Cromwell, now sadly deceased, here in Tucson, around 1980 or so. It was indeed huge, ran on 8" floppy disks (no hard drives) and cost her $15,000, if I recall correctly.
