School spies on kids through student laptops

[Klaus]

Hi,
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:

I still have one of these: Otis King :)
