|The Texas Instruments SR-10 has semi-scientific functions, comparable to the capabilities of a mechanical slide rule, though initially at about ten times the cost. There followed from Texas Instruments, and many other companies, more models of electronic slide rules, with increasing capability and reducing price until within a couple of years the mechanical slide rule became obsolete. ||
