TSNHead
TSNHead was a QBASIC program that kept track of how much time my brothers and I spent on The Sierra Network (TSN) from Sierra Online so that my younger brother would know how much we owed him each month based on a prorated calculation of the monthly service fees. TSN had a rate structure that was similar to modern mobile telephone plans in the United States, where the monthly service fee grants a set amount of hours, and usage over that amount incurs per-hour charges. TSNHead factored the rate plan and the overage charges into its calculations.
The program's name was inspired from a TSN advertisement that resembled a Weekly World News headline with a claim that a baby was born with a TSN head, showing a pixel-block face as the baby's head.
