School spies on kids through student laptops

[--Pete]

Hi,

How could anyone miss such a thing?

Was that "feature" intentionally introduced to that calculator to make people disregard electronic calculation?

It might well have been a problem with that individual machine. In '66 I went through a training course on the Friden Flexowriter (in Saigon -- don't ask:)) and although that was not a calculator, I discovered just how twitchy those old electro-magnetic machines could be. It is amazing that those machines were able to actually perform the calculations for the Manhattan project. I suspect that they required constant maintenance. Clutch pressures, spring tensions, cam angle adjustments, escapement timings. Gives me indigestion just remembering. :whistling:
