Build Quality of Graphing Calcs & Others

[Matt Agajanian]

Hi all.

Since I have a few, I've wondered if graphing calcs are built with the same quality amount of circuitry that 70s calcs (HP Classics, TI: SR-52/56, TI-58/59, etc.) are created with.

On the flip side, it seems to me that the slimline calcs (TI-36X Pro, 30X, Casio fx-115 & 991 series, etc.) are built as disposable items since they're inexpensive (to some extent) to replace.
