Quizplus · Accepted Answer

By incorporating the PDP 11 minicomputer into the Therac-25, AECL was able to rely on software safety features instead of hardware safety features. This allowed for a reduction in costs as well as the ability to shrink the size of the machine. There is no evidence to suggest that this decision had any impact on the stock price of Digital Equipment Corporation or the need for lead shielding.
