If you haven't succeeded yet ..............
I seem to remember there is a glaring
fault in that walkthru. There is NO key on the calculator marked " .. but something else which I seem to remember the person who wrote the walkthrough didn't have on his/her computer KB (but which IS on the game's calculator KB). It COULD have been something like "square root" or whatever!
I think the key you press 'instead' of the double quote symbol ( " ) is NOT the "square root" key but the "divide by" symbol/key which exists on calculator keyboards but not on computer keyboards.
AHuber :-I also wondered about that. If plugging in all the 'correct' keys has no effect, it MAY be because the prerequisite has not been completed ????
The "non-equation" does not come out of the blue. It's ages ago, but I seem to remember that there's a computer (or something) in some woman's house/room ??? You somehow obtain a printout or sheet of paper with the rigmarole written on it.
This may be a 'trigger' to getting the calculator to work.
