Wow! That takes you back to an era just before the HP-35 (equivalent cost $2300 in 2014) appeared, when even the four-function Bomar 901B cost the 2014 equivalent of $800. Impressive...unless you were very wealthy! :-)

I was a junior in electrical engineering at Georgia Tech in 1972, and that Bomar 901B was all I could afford. Well...in truth...I really could not afford it

With respect to the topic...Casio's V.P.A.M. (Visually Perfect Algebraic Method) is one of the best algebraic entry and display methods I've ever come across...in my 42 years. You can enjoy its use in the fx-115ES Plus sold at every Walmart for less than $18. Its Gauss-Kronrod numerical integration function is better than anything from TI or HP, AFAIK. Here is the fx-115ES Plus Manual.
