Kindly observe that my comment states that calculators (if that is what you mean by the ambiguous term "electronics") were NOT allowed on any *test* that I knew about at Georgia Tech, more than 35 years ago. Logically then, I can not answer your charcteristically dismissive question about when calculators became acceptable for tests at GT. I graduated before that era.
Are we clear?
Now, to other things. Here's some more price equivalents, then vs. now, with inflation data from US BLS Inflation Calculator:
As a student I could only afford, barely, a Bomar 901 four-function calculator ($130 in 1972, $675 in 2010). I bought the new TI scientific SR-50 ($150 in 1974, $660 in 2010) after I graduated and was working in the US Navy nuclear program.
I still have these units, working. Those were fun times, watching the competition between HP and TI. TI one-up'd the HP-35 in 1974 with the SR-50, the HP-45 in 1975 with the SR-51A, the HP-65 in 1975 with the SR-52, and the HP-55 in 1976 with the SR-56. The technology and capability of the HP-67 ($450 in 1977, $1610 in 2010) was very soundly trumped by the TI-59 ($300 in 1977, $1075 in 2010) in most respects except the extemely important one of reliability. For that reason alone, I ultimately selected the HP-67 and -97 for use in several military (submarine) applications, reserving the TI-59 for "hobby" use.
