You couldn’t use a computer on standardized testing. The HP48 series had so much built-in functionality that they arguably shouldn’t have been allowed. For myself, a perennially shitty and unmotivated math student in high school, the SAT was really a test of how quickly I could use my HP48—and I practically aced it. The calculator was just that good. As mentioned in another reply, HP does still sell a successor to the HP48 series. But regardless, I don’t think determining the quality of a calculator based on the business decisions of a company known for its persistently and astonishingly terrible corporate choices really makes a whole lot of sense…
