When I got to the house, the computer and its boxes were set up on a table in the garage. There were multiple boxes. The computer itself, the "System Software" - version 3.51, a box of Unix System V utilities, and the most fascinating (to me) thing - a DOS-73 coprocessor. There were also 2 boxes of random sticks of RAM, hard drives and various expansion cards but none of them were for this PC.

The woman told me that her husband had attended the University of Rochester (U of R) in the 80's and was studying computer science and meteorology. He wanted to study the weather and then create software to graph patterns and possibly improve predictions.

In 1987, he went to RIT's college store and purchased this AT&T Unix PC and its accessories. The computer (billed as a PC 7300) cost $695.00, the operating system (Unix System V) cost $195.00 and the "Unix Utilities" cost $329.00. Adding in the 7% sales tax, the grand total comes to $1,304.33! (According to an inflation calculator, that's equivalent to $2,858.06 as of June, 2018.) That does not include the DOS-73 coprocessor, I'm not sure how much that cost.
